Pretty much all of them.
A typical density would be anywhere from a thousand to a million organisms per square centimetre, depending on how moist the foot has been and for how long. Typical residents include diptheroids, micrococci, and many others. Staphylococcus aureus is the most commonly found one.
It is quite simply not true that any antibacterial agent can reduce this count to zero. There are many bacteria that are quite hardy and can resist even alcohol solutions which will kill your own cells. What's more, pores, cracks, and so on are often very difficult for any solution to penetrate. Even if you could completely sterilize the surface of your foot, contact with any non-sterile object (like air) would re-contaminate it in seconds. Link 2 explains that at length.
Any product that claims to completely eliminate bacteria, therefore, is probably exaggerating at best and overtly lying and manipulating the data at worst.

I would count that as a blessing as a germ in the heart would probably cause you a great deal of pain and illness. You can see bacteria,only as a slimy mess of pus though. Check with Satan, might be his doing.

What does bacteria actually do? HOW is it bad?
Bacteria are both harmful and useful to the environment, and animals, including humans. The role of bacteria in disease and infection is important. Some bacteria act as pathogens and cause tetanus, typhoid fever, pneumonia, syphilis, cholera, food-born illness, leprosy, and tuberculosis(TB). Sepsis, a systemic infectious syndrome characterized by shock and massive vasodilation, or localized infection, can be caused by bacteria such as Streptococcus, Staphylococcus, or many gram-negative bacteria. Some bacterial infections can spread throughout the host's body and become systemic. In plants, bacteria cause leaf spot, fireblight, and wilts. The mode of infection includes contact, air, food, water, and insect-borne microorganisms. The hosts infected with the pathogens may be treated with antibiotics, which can be classified as bacteriocidal and bacteriostatic, which at concentrations that can be reached in bodily fluids either kill bacteria or hamper their growth, respectively. Antiseptic measures may be taken to prevent infection by bacteria, for example, by swabbing skin with alcohol prior to piercing the skin with the needle of a syringe. Sterilization of surgical and dental instruments is done to make them sterile or pathogen-free to prevent contamination and infection by bacteria. Sanitizers and disinfectants are used to kill bacteria or other pathogens to prevent contamination and risk of infection.
In soil, microorganisms which reside in the rhizosphere (a zone that includes the root surface and the soil that adheres to the root after gentle shaking) help in the transformation of molecular dinitrogen gas as their source of nitrogen, converting it to nitrogenous compounds in a process known as nitrogen fixation. This serves to provide an easily absorbable form of nitrogen for many plants, which cannot fix nitrogen themselves. Many other bacteria are found as symbionts in humans and other organisms. For example, the presence of the gut flora in the large intestine can help prevent the growth of potentially harmful microbes.
The ability of bacteria to degrade a variety of organic compounds is remarkable. Highly specialized groups of microorganisms play important roles in the mineralization of specific classes of organic compounds. For example, the decomposition of cellulose, which is one of the most abundant constituents of plant tissues, is mainly brought about by aerobic bacteria that belong to the genus Cytophaga. This ability has also been utilized by humans in industry, waste processing, and bioremediation. Bacteria capable of digesting the hydrocarbons in petroleum are often used to clean up oil spills. Some beaches in Prince William Sound were fertilized in an attempt to facilitate the growth of such bacteria after the infamous 1989 Exxon Valdez oil spill. These efforts were effective on beaches that were not too thickly covered in oil.
Bacteria, often in combination with yeasts and molds, are used in the preparation of fermented foods such as cheese, pickles, soy sauce, sauerkraut, vinegar, wine, and yogurt. Using biotechnology techniques, bacteria can be bioengineered for the production of therapeutic drugs, such as insulin, or for the bioremediation of toxic wastes.

Harmful bacterias can be dangerous at many diferent levels;
Since humans discovered antibiotics (penicilyn) it started a little chemical war; Bacterias learn fast and there as some bacterias quite resistent to medicin around and there are a possibility to unkillable bacteria what would be very dangerous to Human Race, something like HIV virus... worst because usually these strong bacterias are quite aggressive and also are able to "teach" other type os bacterias how to defeat antibiotics...
Last 10 year they had discovered only 2 new types of antibiotics.
This seems that we are loosing the war and it explain why you never should stop any kind of antibiotic treatment... or else old dicease can became more resistent...

How might bacteria in the body cause symptoms of fever?
Please try to answer this question or provide some websites that have answers to it.
Thanks!
How might bacteria in the body cause symptoms of fever?
The bacteria themselves do not cause the fever. The elevated body temperature is a response to the presence of bacteria, it is caused by the secretion of signalling molecules known as cytokines and pyrokines by the immune system.
As other answers mentioned, this is a defensive mechanism and can aid the immune cells (macrophages/monocytes and PMNs) in eradticating the infection. However, it is wrong to say that all bacteria are hindered by an increased temperature, many can grow just fine at slightly elevated temperatures. However, it aids the immune cells by speeding up their activities, regardless of the impact on bacteria.
Reply:It secretes some kind of toxin.
Reply:FEVER is a defense mechanism against infection..your body will simple react that there is a bacteria trying to attact your system...example a wound on your feet..if you will not cure it right away you will feel lethargic...soon you will feel some chills...from then on your body will try to counteract with the bacteria to prevent more complication...

How do bacteria adapt to new environments?
By reproducing in huge numbers.
Oversimplification:
Say you've got 1% variation in your genes, so 1 out of every 100 bacteria that derive from you (a bacterium, in this case) is just a teensy-weensy bit different than the others.
If you make millions of offspring, MOST are going to be like you, but some of them are going to be different... (sort of like the brothers and sisters from the same parents aren't all the same.)
Every now and then, one of those differences is going to make the bacteria breed easier.
So say you normally live in salt water, but there is a protein you can make that helps you live without salt... maybe you make enough of this protein that you can survive, oh, fresh water from rain running into your salt water.
Now, say one of your offspring makes a LOT of this protein...
...Now, the offspring of THAT offspring is going to live through the water stopping being salty, right?
If the water then went totally fresh, and the new bacteria were all derived from your one weird offspring, your family of bacteria will be said to have adapted...because now you ALL make that protein. (or you died.)

How are bacteria pathogenic, how does it affect humans?
There are many ways that bacteria can be pathogenic.
First, pathogenicity will depend upon whether the bacterium is Gram-positive or Gram-negative. If Gram-positive, the bacterium can produce endotoxins. These endotoxins are released when the bacterium dies or is destroyed by the body's immune system. Endotoxins will raise fever, possibly cause the body to go into shock or death. Very bad.
In Gram-negative cells, endotoxins can also be produced. Also, in the cell wall of Gram-negatives, there is a component called lipopolysaccharide (LPS). The lipid portion of LPS is called lipid A. Lipid A is very pathogenic and acts like an endotoxin.
Also, some bacteria are able to produce a capsule that surrounds the cell wall. The capsule is made of polysaccharides and/or polypeptides. The capsule is extremely pathogenic, causing the same signs and symptoms listed above.
There are other factors that can cause pathogenesis, but these are the main ones.

Reply:Bacteria (singular: bacterium) are a major group of living organisms. The term "bacteria" has variously applied to all prokaryotes or to a major group of them, otherwise called the eubacteria, depending on ideas about their relationships. Here, bacteria is used specifically to refer to the eubacteria. Another major group of bacteria (used in the broadest, non-taxonomic sense) are the Archaea. The study of bacteria is known as bacteriology, a subfield of microbiology.
Bacteria are the most abundant of all organisms. They are ubiquitous in soil, water, and as symbionts of other organisms. Many pathogens are bacteria. Most are minute, usually only 0.5-5.0 ºm in their longest dimension, although giant bacteria like Thiomargarita namibiensis and Epulopiscium fishelsoni may grow past 0.5 mm in size. They generally have cell walls, like plant and fungal cells, but bacterial cell walls are normally made out of peptidoglycan instead of cellulose (as in plants) or chitin (as in fungi), and are not homologous with eukaryotic cell walls. Many move around using flagella, which are different in structure from the flagella of other groups.
The first bacteria were observed by Anton van Leeuwenhoek in 1674 using a single-lens microscope of his own design. The name bacterium was introduced much later, by Ehrenberg in 1828, derived from the Greek word meaning "small stick". Because of the difficulty in describing individual bacteria and the importance of their discovery to fields such as medicine, biochemistry, and geochemistry, the history of bacteriology is generally described as the history of microbiology.
As prokaryotes (organisms without the cell nucleus)all bacteria have a relatively simple cell structure lacking a cell nucleus and organelles such as mitochondria and chloroplasts. Most bacteria are relatively small and possess distinctive cell and colony morphologies (shapes) as described below. The most important bacterial structural characteristic is the cell wall. Bacteria can be divided into two groups (Gram positive and Gram negative) based on differences in cell wall structure as revealed by Gram staining. Gram positive bacteria possess a cell wall containing a thick peptidoglycan (called Murein in older sources) layer and teichoic acids while Gram negative bacteria have an outer, lipopolysaccharide-containing membrane and a thin peptidoglycan layer located in the periplasm (the region between the outer and cytoplasmic membranes).
Many bacteria contain other extracellular structures such as flagella and fimbriae which are used for motility (movement), attachment, and conjugation respectively. Some bacteria also contain capsules or slime layers that also facilitate bacterial attachment to surfaces and biofilm formation. Bacteria contain relatively few intracellular structures compared to eukaryotes but do contain a tightly supercoiled chromosome, ribosomes, and several other species-specific structures such as intracellular membranes, nutrient storage structures, gas vesicles, and magnetosomes. Some bacteria are capable of forming endospores which allows them to survive extreme environmental and chemical stresses. This property is restricted to specific Gram positive organisms such as Bacillus and Clostridium.
In contrast to higher organisms, bacteria exhibit an extremely wide variety of metabolic types. In fact, it is widely accepted that eukaryotic metabolism is largely a derivative of bacterial metabolism with mitochondria having descended from a lineage within the -Proteobacteria and chloroplasts from the Cyanobacteria by ancient endosymbiotic events. Bacterial metabolism can be divided broadly on the basis of the kind of energy used for growth, electron donors and electron acceptors and by the source of carbon used. Most bacteria are heterotrophic; using organic carbon compounds as both carbon and energy sources.
In aerobic organisms, oxygen is used as the terminal electron acceptor. In anaerobic organisms other inorganic compounds, such as nitrate, sulfate or carbon dioxide as terminal electron acceptors leading to the environmentally important processes of denitrification, sulfate reduction and acetogenesis, respectively. Non-respiratory anaerobes use fermentation to generate energy and reducing power, secreting metabolic by-products (such as ethanol in brewing) as waste.
Facultative anaerobes can switch between fermentation and different terminal electron acceptors depending on the environmental conditions in which they find themselves. As an alternative to heterotrophy many bacteria are autotrophic, fixing carbon dioxide into cell mass. Energy metabolism of bacteria is either based on phototrophy or chemotrophy, i. e. the use of either light or exergonic chemical reactions for fueling life processes. Lithotrophic bacteria use inorganic electron donors for respiration (chemolithotrophs) or biosynthesis and carbon dioxide fixation (photolithotrophs), opposed by organotrophs which need organic compounds as electron donors for biosynthetic reactions (and mostly as well as carbon sources).
Common inorganic electron donors are hydrogen, carbon monoxide, ammonia (leading to nitrification), ferrous iron, other reduced metal ions or even elemental iron and several reduced sulfur compounds. Additionally, methane metabolism, although formally counted as organotrophic, is actually more related to lithotrophic metabolic pathways. In both aerobic phototrophy and chemolithotrophy oxygen is used as a terminal electron acceptor, while under anaerobic conditions inorganic compounds (see above) are used instead. Most photolithotrophic and chemolithotrophic organisms are autotrophic, meaning that they obtain cellular carbon by fixation of carbon dioxide, whereas photoorganotrophic and chemoorganotrophic organisms are heterotrophic. In addition to carbon, some organisms also fix nitrogen gas (nitrogen fixation).
This environmentally important trait can be found in bacteria of nearly all the metabolic types listed above but is not universal. The distribution of metabolic traits within a group of organisms has traditionally been used to define their taxonomy, although these traits often do not correspond with genetic techniques.
All bacteria reproduce through asexual reproduction (binary fission) which results in cell division. Two identical clone daughter cells are produced. Some bacteria, while still reproducing asexually, form more complex reproductive structures that facilitate the dispersal of the newly-formed daughter cells. Examples include fruiting body formation by Myxococcus and arial hyphae formation by Streptomyces.
In the laboratory, bacteria are usually grown using two methods, solid and liquid. Solid growth media such as agar plates are used to isolate pure cultures of a bacterial strain. When quantitation of growth or large volumes of cells are required liquid growth media are generally used. Growth in liquid media, with stirring, most often occurs as an even cell suspension making the cultures easier to divide and transfer compared to solid media, although the isolation of individual cells from liquid media is extremely difficult. In both liquid and solid media there exist a finite amount of nutrients, which allows for the study of the bacterial cell cycle.
These limitations can be avoided by the use of a chemostat, which maintains a bacterial culture under steady-state conditions by the continuous addition of nutrients and the removal of waste products and cells. Large chemostats are often used for industrial-scale microbial processes.Most techniques commonly used to grow bacteria are designed to optimise the amount of cells produced, the amount of time needed to produce them, and the cost to produce them. In a bacterium's natural environment nutrients are limited, meaning that bacteria cannot continue to reproduce indefinitely. This constant limitation of nutrients has led the evolution of many different growth strategies in different types of organisms.
Some possess the ability to grow extremely rapidly when nutrients become available, such as the formation of algal (and cyanobacterial) blooms that often occur in lakes during the summer. Other organisms have devised more specialized strategies to make them more successful in a harsh environment, such as the production of antibiotics by Streptomyces; often at the expense of a slower growth rate. In a natural environment, many organisms live in communities (e.g. biofilms) which may allow for increased supply of nutrients and protection of environmental stresses. Often these relationships are essential for growth of a particular organism or group of organisms (syntrophy).
These evolutionary tactics to overcome nutrient limitation must be accounted for in an industrial/laboratory bacterial growth experiment. For instance bacteria that tend to agglutinate may need more vigorous stirring to break apart any large bacterial masses. The main growth attribute that must be understood for controlled growth is that bacteria have defined growth phases.A controlled bacterial growth will follow three distinct phases. Nearly all cultures start from taking a relatively old stock of bacteria and diluting them in to fresh media; these cells need to adapt to the nutrient rich environment.
The first phase of growth is the lag phase, a period of slow growth most often attributed to the need for cells to adapt to fast growth. The lag phase has high biosynthesis rates; enzymes needed to metabolise a variety of substrates are produced. The second phase of growth is the logarithmic phase (log phase), also known as the exponential phase. The log phase is marked by rapid exponential growth. The rate at which cells grow during this phase is known as the growth rate (k). The time it takes the cells to double during the log phase is known as the generation time (g).
During the log phase, nutrients are metabolised at maximum speed until they are all gone. The final phase of growth is the stationary phase. This phase of growth is caused by depleted nutrients. The cells begin to shut down their metabolic activity, as well as break-down their own non-essential proteins. The stationary phase is a transition from rapid growth to dormancy. The cells turn off all non-essential functions, such as bacterial conjugation.
Motile bacteria can move about, using flagella, bacterial gliding, or changes of buoyancy. A unique group of bacteria, the spirochaetes, have structures similar to flagella, called axial filaments, between two membranes in the periplasmic space. They have a distinctive helical body that twists about as it moves.
Bacterial flagella are arranged in many different ways. Bacteria can have a single polar flagellum at one end of a cell, clusters of many flagella at one end or flagella scattered all over the cell, as with peritrichous. Many bacteria (such as E.coli) have two distinct modes of movement: forward movement (swimming) and tumbling. The tumbling allows them to reorient and introduces an important element of randomness in their forward movement.
Motile bacteria are attracted or repelled by certain stimuli, behaviors called taxes - for instance, chemotaxis, phototaxis, mechanotaxis, and magnetotaxis. In one peculiar group, the myxobacteria, individual bacteria attract to form swarms and may differentiate to form fruiting bodies. The myxobacteria move only when on solid surfaces, unlike E. coli which is motile in liquid or solid media.

Reply:It's not necessarily that they are formed. They grow. Bacteria is found everywhere- on everything from your skin to your food. Most bacteria is part of our normal flora. On the body, bacteria can act as a protective agent- keeping out potentially harmful bacteria. Think about it this way. I see that you're a 30 Seconds to Mars fan. Think about going to a show.

Now onto how bacteria grow. (Note that this is a very VERY short version of what I've learned in my microbiology class.And it probably doesn't even begin to cover all of it. :))
There are many MANY different types of bacteria. Just like other living things (bc yes all bacteria are living organisms), each type requires something different in order to grow; temperature, light, food source, water... you get the picture. Provided an ideal environment, bacteria will multiply.

Reply:Bacteria do not form out of nothing, or out of dirt, on a daily basis. That concept is called spontaneous generation, and informed society has not believed in that for centuries. Abiogenesis is the concept that the formation of organic matter from inorganic matter happened once, and took a huge number of years to do so.
Bacteria are alive. They multiple to increase their numbers, like humans, or cats, or lobsters. They also require the proper amount of nutrients, and to stay away from things that are toxic to them. But unlike animals, they do not mate, but reproduce asexually. They divide (see link below).
Bacteria are omnipresent, every surface you can see has them. Most are harmless, or even beneficial to us. Sometimes, one of these bacteria get into a place that they aren't suppose to be, and they begin to grow, and cause an infection. It's not the stepping on a rusty nail that causes tetanus, is the bacteria Clostridium tetani that is likely living on that nail.
There you go good sir.
How are bacteria formed? ahh i know its a useless question but im hellbent to find out how?
JUst by the air and people, and dead skin cells and all that awsome stuff..

Reply:Bacteria (singular: bacterium) are a major group of living organisms. The term "bacteria" has variously applied to all prokaryotes or to a major group of them, otherwise called the eubacteria, depending on ideas about their relationships. Here, bacteria is used specifically to refer to the eubacteria. Another major group of bacteria (used in the broadest, non-taxonomic sense) are the Archaea. The study of bacteria is known as bacteriology, a subfield of microbiology.
Bacteria are the most abundant of all organisms. They are ubiquitous in soil, water, and as symbionts of other organisms. Many pathogens are bacteria. Most are minute, usually only 0.5-5.0 ºm in their longest dimension, although giant bacteria like Thiomargarita namibiensis and Epulopiscium fishelsoni may grow past 0.5 mm in size. They generally have cell walls, like plant and fungal cells, but bacterial cell walls are normally made out of peptidoglycan instead of cellulose (as in plants) or chitin (as in fungi), and are not homologous with eukaryotic cell walls. Many move around using flagella, which are different in structure from the flagella of other groups.
The first bacteria were observed by Anton van Leeuwenhoek in 1674 using a single-lens microscope of his own design. The name bacterium was introduced much later, by Ehrenberg in 1828, derived from the Greek word meaning "small stick". Because of the difficulty in describing individual bacteria and the importance of their discovery to fields such as medicine, biochemistry, and geochemistry, the history of bacteriology is generally described as the history of microbiology.
As prokaryotes (organisms without the cell nucleus)all bacteria have a relatively simple cell structure lacking a cell nucleus and organelles such as mitochondria and chloroplasts. Most bacteria are relatively small and possess distinctive cell and colony morphologies (shapes) as described below. The most important bacterial structural characteristic is the cell wall. Bacteria can be divided into two groups (Gram positive and Gram negative) based on differences in cell wall structure as revealed by Gram staining. Gram positive bacteria possess a cell wall containing a thick peptidoglycan (called Murein in older sources) layer and teichoic acids while Gram negative bacteria have an outer, lipopolysaccharide-containing membrane and a thin peptidoglycan layer located in the periplasm (the region between the outer and cytoplasmic membranes).
Many bacteria contain other extracellular structures such as flagella and fimbriae which are used for motility (movement), attachment, and conjugation respectively. Some bacteria also contain capsules or slime layers that also facilitate bacterial attachment to surfaces and biofilm formation. Bacteria contain relatively few intracellular structures compared to eukaryotes but do contain a tightly supercoiled chromosome, ribosomes, and several other species-specific structures such as intracellular membranes, nutrient storage structures, gas vesicles, and magnetosomes. Some bacteria are capable of forming endospores which allows them to survive extreme environmental and chemical stresses. This property is restricted to specific Gram positive organisms such as Bacillus and Clostridium.
In contrast to higher organisms, bacteria exhibit an extremely wide variety of metabolic types. In fact, it is widely accepted that eukaryotic metabolism is largely a derivative of bacterial metabolism with mitochondria having descended from a lineage within the -Proteobacteria and chloroplasts from the Cyanobacteria by ancient endosymbiotic events. Bacterial metabolism can be divided broadly on the basis of the kind of energy used for growth, electron donors and electron acceptors and by the source of carbon used. Most bacteria are heterotrophic; using organic carbon compounds as both carbon and energy sources.
In aerobic organisms, oxygen is used as the terminal electron acceptor. In anaerobic organisms other inorganic compounds, such as nitrate, sulfate or carbon dioxide as terminal electron acceptors leading to the environmentally important processes of denitrification, sulfate reduction and acetogenesis, respectively. Non-respiratory anaerobes use fermentation to generate energy and reducing power, secreting metabolic by-products (such as ethanol in brewing) as waste.
Facultative anaerobes can switch between fermentation and different terminal electron acceptors depending on the environmental conditions in which they find themselves. As an alternative to heterotrophy many bacteria are autotrophic, fixing carbon dioxide into cell mass. Energy metabolism of bacteria is either based on phototrophy or chemotrophy, i. e. the use of either light or exergonic chemical reactions for fueling life processes. Lithotrophic bacteria use inorganic electron donors for respiration (chemolithotrophs) or biosynthesis and carbon dioxide fixation (photolithotrophs), opposed by organotrophs which need organic compounds as electron donors for biosynthetic reactions (and mostly as well as carbon sources).
Common inorganic electron donors are hydrogen, carbon monoxide, ammonia (leading to nitrification), ferrous iron, other reduced metal ions or even elemental iron and several reduced sulfur compounds. Additionally, methane metabolism, although formally counted as organotrophic, is actually more related to lithotrophic metabolic pathways. In both aerobic phototrophy and chemolithotrophy oxygen is used as a terminal electron acceptor, while under anaerobic conditions inorganic compounds (see above) are used instead. Most photolithotrophic and chemolithotrophic organisms are autotrophic, meaning that they obtain cellular carbon by fixation of carbon dioxide, whereas photoorganotrophic and chemoorganotrophic organisms are heterotrophic. In addition to carbon, some organisms also fix nitrogen gas (nitrogen fixation).
This environmentally important trait can be found in bacteria of nearly all the metabolic types listed above but is not universal. The distribution of metabolic traits within a group of organisms has traditionally been used to define their taxonomy, although these traits often do not correspond with genetic techniques.
All bacteria reproduce through asexual reproduction (binary fission) which results in cell division. Two identical clone daughter cells are produced. Some bacteria, while still reproducing asexually, form more complex reproductive structures that facilitate the dispersal of the newly-formed daughter cells. Examples include fruiting body formation by Myxococcus and arial hyphae formation by Streptomyces.

What are Bacteria Cultures?
Bacteria cultures are cultures of bacteria. Sorry, I shall try to make it more specific.
In a bacteria culture, you would have your growth culture which is normally the agar agar medium required for the bacteria to grow on it; it contains all sorts of nutrients required for either general growth of bacteria or only specific growth for a certain kind that you want. Then you grow your bacteria in on the culture medium itself. Normally you would do it near a Bunsen flame to keep the place flame sterilized.
As far as my microbiology lesson goes, there are 2 types of bacteria culture. The normal one and the pure culture. Within the normal culture, you have the pour plate and the spread plate. These are ways to determine whether the bacteria can survive at low oxygen content. In the pure culture, you have the streak plate and the pour plate again. Again, this is a way to test for the survivability with the absence of oxygen.
Normally the reason for having bacteria culture is to test the water supply in the area but there could be other uses such as research and so on. Hope I helped you.

when the dough i moved to another area with a different culture bacteria , the bread tastes different

How much bacteria/germs would you estimate is on your hands, keyboard, and mouse right now?
when I took microbiology in lab we would take a cotton swab and find different articles to swab.. We would then culture the germs on these articles, desks, money, doorknob handles, seats. We found staph on money. What we found is there is no escaping germs and then we used different products such as chlorine to disinfect them.. Unless you allow the chlorine to work for a good period of time the germs just continue to grow. You can't avoid germs just hope you or whoever you have around you uses good hygiene practices.

Do the bacteria in the digestive tract die when you take antibiotics?
Yes, antibiotics generally attack all bacteria in the body. This is why you will notice your skin clear up as you take antibiotics for an internal infection. Good bacteria and bad bacteria all are attacked. Various antibiotics can attack different strains more than others.
Do the bacteria in the digestive tract die when you take antibiotics?
Depending on the antibiotice, that can occur. Their is a new theory that the appendix actually acts as a shelter for bacteria, so that when this happens (it can also occur with infection of some hostile bacteria) the intestine can be repopulated.
You can minmize the symptoms when this occurs by eating yogurt with live cultures.
Reply:Of course. That isn't to say the gut is sterilized, by any means, but a lot of bugs die, and it's enough that in one patient of six to one in fifteen, diarrhea follows a course of simple outpatient antibiotic therapy precisely because of the change in intestinal flora.
Reply:the antibiotics, contain substances that inhibit either the growth of bacteria, lyse them or in any other form stop them from reproducing further generations. THEY CANNOT DIFFERENTIATE BETWEEN GOOD AND BAD BACTERIA AND DO KILL BACTERIA IN THE DIGESTIVE TRACT TOO. For eg, E.Coli present in the digestive tract produces vitamin B12 as per body requirement, a person on high antibiotic dose often experiences deficiency symptoms of Vit B12 because the bacteria producing the vitamin in the tract have been killed by the high antibiotic dosage.

There is bacteria in every opening of your body.
Reply:In spite of nasal cavity's impressive antimicrobial defenses, microorganisms do enter the upper respiratory system. Because it is warm, moist, and nutrient-rich it offers a favorable environment for their growth. Indeed, the upper respiratory system is densely colonized by commensal microorganisms, including streptococci, lactobacilli, and some Gram-negatives such as Moraxella catarrhalis. But that's as far as they normally get. In healthy people, the lower respiratory system (as well as the sinuses and middle ear) is sterile.

How might bacteria in the body cause symptoms of fever?
Bacteria does not cause fever directly. The body's first autoimmune system response is to raise the temperature to a level which most bacteria can't survive in and to increase blood flow to the infected area. So the fever is there to help fight off the infection.
How might bacteria in the body cause symptoms of fever?
pyrogens secretes by toxic bacteria or released from degenerative tissues of the body cause fever during disease conditions

How does bacteria cause leporsy?
leprosy is a specific bacteria that atacks the connective tissue and mutates and destroys it. Itcan be prevented by drugs, and healed with antibiotics. However, damaged tissue cannot be regrown.
How does bacteria cause leporsy?
Leprosy is caused by the organism Mycobacterium leprae. It is not very contagious (difficult to transmit) and has a long incubation period (time before symptoms appear), which makes it difficult to determine where or when the disease was contracted. Children are more susceptible than adults to contracting the disease.
Leprosy has two common forms, tuberculoid and lepromatous, and these have been further subdivided. Both forms produce sores on the skin, but the lepromatous form is most severe, producing large, disfiguring nodules (lumps and bumps).
All forms of the disease eventually cause peripheral neurological damage (nerve damage in the arms and legs) which causes sensory loss in the skin and muscle weakness. People with long-term leprosy may lose the use of their hands or feet due to repeated injury resulting from lack of sensation.
Medications used to eliminate the microorganism and to reduce symptoms include:
* Dapsone
* Rifampin
* Clofazimine
* Ethionamide
* Aspirin, prednisone, or thalidomide are used for the control of inflammation (e.g., "erythema nodosum leprosum") that may occur with therapy
Reply:Leprosy is not actually caused by a bacteria. The "leprosy bacteria" carries a "mini virus" that actually does the damage.

How many bacteria are found on the human hand?
Millions! But don't worry - very few of them are 'bad' bacteria - bacteria that will give you infections. On my personal rant - all these tv programmes that say there's more bacteria on your chopping board than your toilet seat and go round checking the number of bacteria in different parts of peoples homes to check they're cleaning properly etc. etc. are really invalid - bacteria can multiply extreemely quickly - just one could make you sick (though if you get many at once they will be more difficult for your immune system to deal with therefore are more likely to make you sick), so the number is irrelivant - it's the type and diversity of bacteria that matter.

Reply:In taxonomy, the classification of viruses is rather difficult due to the lack of a fossil record and the dispute over whether they are living or non-living. They do not fit easily into any of the domains of biological classification and therefore classification begins at the family rank. However, the domain name of Acytota (without cells) has been suggested. This would place viruses on a par with the other domains of Eubacteria, Archaea, and Eukarya. Not all families are currently classified into orders, nor all genera classified into families.

How are bacteria and fungi used to make foods that we eat?
Yogurt and cheese - Lactobacillus is the bacteria that is used for these.
Bread, wine/beer - Fungi in the form of yeast are used for these.
Yeast feeds off the sugars that are around and generate carbon dioxide which creates the bubbles that helps bread rise. It ferments the sugars to help make wine and beer.
Bacteria is helped used to process certain foods to alter the way they are - like from milk to yogurt or cheese. The presence of this bacteria helps prevent other bacteria from forming, thus helping to preserve milk by making cheese for example.

How do bacteria conjugate?
Some sources say that during conjugation the doner bacterium uses "sex pili" to grasp onto the recipient bacterium, and then a "conjugation tube" is formed through which the strand of DNA is transferred from the doner to the recipient (http://www.biostudio.com/d_%20Bacterial%... However other sources say that the doner attaches to the recipient by its sex pilus, and the DNA is transferred through the sex pilus(http://www.hhmi.org/biointeractive/anima... Thus the latter understanding of bacterial conjugation says that the sex pilus IS the conjugation tube. Which of these is correct?
How do bacteria conjugate?
The good thing to remember is that the F factor allows conjucation. The F factor can be found on a plasmid or the chromosome of a bacterium.
The F factor codes for the pili that allows conjugation.
The F pilus enables an F carrying bacterium to contact an F negative bacterium and to initiate conjugation.
The F pilus does not provide the means of transport for DNA thought. It is used for recognition.
There are a series of Tra genes that actually seem to allow the transfer of DNA.
If that gives you an answer I would take it as good. This is still an area of active research. There is much more in the source I used about specific genes but they do seem to get a little iffy about stating exact actions.

How conjugation provides greater diversity among bacteria ??????????????????please helpp !!! really badly!!?
Conjugation occurs when bacterial cells come in contact and exchange portions of their DNA molecules. Thus, one bacterium can change when there is a change (or exchange) in DNA.
This switching of genes is comparable to what occurs during Prophase I of meiosis. During Prophase I, chromosomes appear and the chromosomes that are the same size and shape and responsible for the same traits (one had its origin in the mother and one of the pair came from the father and are called homologous chromosomes) pair up and a similar event occurs. In this case it is called crossing over and groups of genes from one chromosome will switch to the other member of the pair.
Bacterial conjugation, like crossing over, mixes up the genes and the gene pool and leads to diversity within the species.
Reply:Normally bacteria "reproduce"by binary fission..which literally means to "break into 2". A mother cell will divide into two IDENTICAL daughter cells....these will also divide to produce 2 IDENTICAL daughter cells. So while this method is rapid and produces lots of bacteria, the result is that they will be all ( almost) identical in their genetics.....this means they will respond in the same way in how virulent ( how "nasty"the disease they produce ) may be, how they respond to antibiotics, in that they may be all resistant or all suseptable to one/many antibiotics, etc."This type of reproduction is considered to be assexual reprodution where there is only 1 parent and offspring are identical to the parent.
In certain cases, bacterial will reproduce by conjugation, which is the equivalent of sexual reproduction..where there are 2 parents and the DNA of both are combined. The result is genetically different offspring. This means that the new combinations of genes in the new bacteria oofspring may make them resistant to antibiotics ( or less resistant..its just the luck of the draw)....it could make them more virulent than either parent ( or less)...it allows there to be more vairation i( genetically speaking) and this is considered to be better as most plants and animals reproduce very successfully this way. It gives rise to "new"traits etc much more quickly than assexual reproduction ( binary fisson in this case) and these CAN benefit the bacteria greatly if they are the right combination of genes.
How conjugation provides greater diversity among bacteria ??????????????????please helpp !!! really badly!!?
Conjugation occurs when bacterial cells come in contact and exchange portions of their DNA molecules. Thus, one bacterium can change when there is a change (or exchange) in DNA.

How do bacteria spoil food?
There are different spoilage bacteria and each reproduces at specific
temperatures. Some can grow at the low temperatures
in the refrigerator or freezer. Others grow well at room temperature and in
the "Danger Zone." Bacteria will grow anywhere they
have access to nutrients and water. Under the correct conditions, spoilage
bacteria reproduce rapidly and the populations can grow
very large. In some cases, they can double their numbers in as little as 30
minutes. The large number of microorganisms and their
waste products cause the objectionable changes in odor, taste, and texture
How do bacteria spoil food?
By multiplying to the point of consuming or decomposing the host food.

How is bacteria caused? And how is mildew caused?
Bacteria is transfered from an existing colony, usually via contact. mildew is a fungus that is spread via spores, somewhat like "seeds" that are airborne. Both require a suitable medium to grow in.

Does anyone know the type of bacteria found in bread and the biochemical test for that bacteria?
mold is not a bacteria, it is a fungus. Lactobacilli can be found in some types of bread eg sourdough bread.
Gram stains, colony morphology, catalase test, glucose fermentation tests, lactose fermentation tests, starch hydrolysis, nitrate broth tests etc can help identify this organism (these are basic tests for identifying many different types of bacteria).

What comon bacteria can be found in common tap water?
There are laws governing the treatment of tap water. They require that the level of bacteria be very low. For the most part, the water is bacteria free. They are especially careful about fecal contamination. In some cities when there is a lot of rain the sewer system will dump into the local river/lake which is also the water supply. This means that the treatment plant has to be extra vigilant in making sure no pathogenic bacteria survive the treatment process. In well water (private wells do not go through a treatment facility) you often find P. vulgaris, which can make the water smell very badly.

Can candida bacteria survive in a warm strong coffee?
Candida is a fungus, not a bacteria.
If the coffee is hot, no, probably not. Just being warm, however, candida would thrive in that environment. I don't think that the coffee part has anything to do with it.

How does Bacteria grows into cosmetics? or in mascara?
Most bacteria in cosmetics, comes from a host. That's why you really don't want to let other people use your make-up. Another way is if it has expired it's shelf life or has been exposed to other elements, (Falling in water, laying in a hot car, etc.) that will promote bacteria growth. Alot of make-up usually consists of bat droppings(guano). So check the expiration dates, and only you should use your make-up.

Why store bacteria culture in agar slant?
There are several reasons a slant is best for culture storage (and none of them are real scientific!):
1) Surface area - by making the tube at a slant, you increase the surface area as opposed to just a flat surface;
2) Size - a test tube is much easier to store than a beaker - you can fit nearly 20 test tubes in the same area as one beaker;
3) Moisture - plates, when stored, tend to dehydrate very quickly. A capped tube will retain moisture much longer;
4) Ease - while it is a pain to make slants, once the microorganism is transfered, you put it in a frige (2-8 Celcius) and leave it for up to 6 months. If you used a plate you would have to transfer every week; a beaker would mean transfering every month (and they spill so easy!)
One thing to remember about slants and storing microorganisms -- the more often you transfer them, the less like the 'original' they become. If you are working with a specific microorganism because of a unique characteristic try the following:
1) Grow a very heavy inoculum of the orginal on a plate with approriate medium.
2) Make several (5-10) slants from that plate.
3) If you plan to work with your microorganism, transfer a fresh culture from one of the slants to a couple plates.
4) Use those plates for about a week and then get a new inoculum from the original slants.
In general, do not transfer more than 3 times from the original culture!

How are bacteria, viruses and cells similar and different?
A viruses is a small structure that has a protein coat with a pieces of genetic material. It invades the cell of its host and uses the hosts DNA to replicate its own genetic material. Once the cell has replicated the viruses DNA the cell ruptures and the viral DNA is sent throughout the hosts body. A virus is not technically classified as a living thing. It is not able to replicate and reproduce with out a host.
A bacteria is classified as a living thing. It is a prokaryotic organism with the ability to reproduce using its own genetic material DNA/ RNA.

Reply:The basic plant cell has a similar construction to the animal cell, but does not have centrioles, lysosomes, cilia, or flagella. It does have additional structures, including a rigid cell wall, central vacuole, plasmodesmata, and chloroplasts.
Animal cells are typical of the eukaryotic cell type, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles.
BACTERIA CELLS
There are two types of cells: prokaryotic cells and eukaryotic cells.
The simplest cells are prokaryotic cells like bacteria. Eukaryotic cells are more complex cells and are found in plants, animals and fungi. (visit this site for more information and animation http://www.bbc.co.uk/education/asguru/bi...
(picture of bacteria http://micro.magnet.fsu.edu/cells/procar...
Capsule - Some species of bacteria have a third protective covering, a capsule made up of polysaccharides (complex carbohydrates). Capsules play a number of roles, but the most important are to keep the bacterium from drying out and to protect it from phagocytosis (engulfing) by larger microorganisms. The capsule is a major virulence factor in the major disease-causing bacteria, such as Escherichia coli and Streptococcus pneumoniae. Nonencapsulated mutants of these organisms are avirulent, i.e. they don't cause disease.
Cell Envelope - The cell envelope is made up of two to three layers: the interior cytoplasmic membrane, the cell wall, and -- in some species of bacteria -- an outer capsule.
Cell Wall - Each bacterium is enclosed by a rigid cell wall composed of peptidoglycan, a protein-sugar (polysaccharide) molecule. The wall gives the cell its shape and surrounds the cytoplasmic membrane, protecting it from the environment. It also helps to anchor appendages like the pili and flagella, which originate in the cytoplasm membrane and protrude through the wall to the outside. The strength of the wall is responsible for keeping the cell from bursting when there are large differences in osmotic pressure between the cytoplasm and the environment.
Cell wall composition varies widely amongst bacteria and is one of the most important factors in bacterial species analysis and differentiation. For example, a relatively thick, meshlike structure that makes it possible to distinguish two basic types of bacteria. A technique devised by Danish physician Hans Christian Gram in 1884, uses a staining and washing technique to differentiate between the two forms. When exposed to a gram stain, gram-positive bacteria retain the purple color of the stain because the structure of their cell walls traps the dye. In gram-negative bacteria, the cell wall is thin and releases the dye readily when washed with an alcohol or acetone solution.
Cytoplasm - The cytoplasm, or protoplasm, of bacterial cells is where the functions for cell growth, metabolism, and replication are carried out. It is a gel-like matrix composed of water, enzymes, nutrients, wastes, and gases and contains cell structures such as ribosomes, a chromosome, and plasmids. The cell envelope encases the cytoplasm and all its components. Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus. The chromosome, a single, continuous strand of DNA, is localized, but not contained, in a region of the cell called the nucleoid. All the other cellular components are scattered throughout the cytoplasm.
Cytoplasmic Membrane - A layer of phospholipids and proteins, called the cytoplasmic membrane, encloses the interior of the bacterium, regulating the flow of materials in and out of the cell. This is a structural trait bacteria share with all other living cells; a barrier that allows them to selectively interact with their environment. Membranes are highly organized and asymmetric having two sides, each side with a different surface and different functions. Membranes are also dynamic, constantly adapting to different conditions.
One of those components, plasmids, are small, extrachromosomal genetic structures carried by many strains of bacteria. Like the chromosome, plasmids are made of a circular piece of DNA. Unlike the chromosome, they are not involved in reproduction. Only the chromosome has the genetic instructions for initiating and carrying out cell division, or binary fission, the primary means of reproduction in bacteria. Plasmids replicate independently of the chromosome and, while not essential for survival, appear to give bacteria a selective advantage.
Plasmids are passed on to other bacteria through two means. For most plasmid types, copies in the cytoplasm are passed on to daughter cells during binary fission. Other types of plasmids, however, form a tubelike structure at the surface called a pilus that passes copies of the plasmid to other bacteria during conjugation, a process by which bacteria exchange genetic information. Plasmids have been shown to be instrumental in the transmission of special properties, such as antibiotic drug resistance, resistance to heavy metals, and virulence factors necessary for infection of animal or plant hosts. The ability to insert specific genes into plasmids have made them extremely useful tools in the fields of molecular biology and genetics, specifically in the area of genetic engineering.
Flagella - Flagella (singular, flagellum) are hairlike structures that provide a means of locomotion for those bacteria that have them. They can be found at either or both ends of a bacterium or all over its surface. The flagella beat in a propeller-like motion to help the bacterium move toward nutrients; away from toxic chemicals; or, in the case of the photosynthetic cyanobacteria; toward the light.
Nucleoid - The nucleoid is a region of cytoplasm where the chromosomal DNA is located. It is not a membrane bound nucleus, but simply an area of the cytoplasm where the strands of DNA are found. Most bacteria have a single, circular chromosome that is responsible for replication, although a few species do have two or more. Smaller circular auxiliary DNA strands, called plasmids, are also found in the cytoplasm.
Pili - Many species of bacteria have pili (singular, pilus), small hairlike projections emerging from the outside cell surface. These outgrowths assist the bacteria in attaching to other cells and surfaces, such as teeth, intestines, and rocks. Without pili, many disease-causing bacteria lose their ability to infect because they're unable to attach to host tissue. Specialized pili are used for conjugation, during which two bacteria exchange fragments of plasmid DNA.
Ribosomes - Ribosomes are microscopic "factories" found in all cells, including bacteria. They translate the genetic code from the molecular language of nucleic acid to that of amino acids—the building blocks of proteins. Proteins are the molecules that perform all the functions of cells and living organisms. Bacterial ribosomes are similar to those of eukaryotes, but are smaller and have a slightly different composition and molecular structure. Bacterial ribosomes are never bound to other organelles as they sometimes are (bound to the endoplasmic reticulum) in eukaryotes, but are free-standing structures distributed throughout the cytoplasm. There are sufficient differences between bacterial ribosomes and eukaryotic ribosomes that some antibiotics will inhibit the functioning of bacterial ribosomes, but not a eukaryote's, thus killing bacteria but not the eukaryotic organisms they are infecting.

The capsule is a major virulence factor in the major disease-causing bacteria, such as Escherichia coli and Streptococcus pneumoniae. Nonencapsulated mutants of these organisms are avirulent, i.e. they don't cause disease.
Cell Envelope - The cell envelope is made up of two to three layers: the interior cytoplasmic membrane, the cell wall, and -- in some species of bacteria -- an outer capsule.
Cell Wall - Each bacterium is enclosed by a rigid cell wall composed of peptidoglycan, a protein-sugar (polysaccharide) molecule. The wall gives the cell its shape and surrounds the cytoplasmic membrane, protecting it from the environment. It also helps to anchor appendages like the pili and flagella, which originate in the cytoplasm membrane and protrude through the wall to the outside. The strength of the wall is responsible for keeping the cell from bursting when there are large differences in osmotic pressure between the cytoplasm and the environment.
Cell wall composition varies widely amongst bacteria and is one of the most important factors in bacterial species analysis and differentiation. For example, a relatively thick, meshlike structure that makes it possible to distinguish two basic types of bacteria. A technique devised by Danish physician Hans Christian Gram in 1884, uses a staining and washing technique to differentiate between the two forms. When exposed to a gram stain, gram-positive bacteria retain the purple color of the stain because the structure of their cell walls traps the dye. In gram-negative bacteria, the cell wall is thin and releases the dye readily when washed with an alcohol or acetone solution.
Cytoplasm - The cytoplasm, or protoplasm, of bacterial cells is where the functions for cell growth, metabolism, and replication are carried out. It is a gel-like matrix composed of water, enzymes, nutrients, wastes, and gases and contains cell structures such as ribosomes, a chromosome, and plasmids. The cell envelope encases the cytoplasm and all its components. Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus. The chromosome, a single, continuous strand of DNA, is localized, but not contained, in a region of the cell called the nucleoid. All the other cellular components are scattered throughout the cytoplasm.
Cytoplasmic Membrane - A layer of phospholipids and proteins, called the cytoplasmic membrane, encloses the interior of the bacterium, regulating the flow of materials in and out of the cell. This is a structural trait bacteria share with all other living cells; a barrier that allows them to selectively interact with their environment. Membranes are highly organized and asymmetric having two sides, each side with a different surface and different functions. Membranes are also dynamic, constantly adapting to different conditions.
One of those components, plasmids, are small, extrachromosomal genetic structures carried by many strains of bacteria. Like the chromosome, plasmids are made of a circular piece of DNA. Unlike the chromosome, they are not involved in reproduction. Only the chromosome has the genetic instructions for initiating and carrying out cell division, or binary fission, the primary means of reproduction in bacteria. Plasmids replicate independently of the chromosome and, while not essential for survival, appear to give bacteria a selective advantage.
Plasmids are passed on to other bacteria through two means. For most plasmid types, copies in the cytoplasm are passed on to daughter cells during binary fission. Other types of plasmids, however, form a tubelike structure at the surface called a pilus that passes copies of the plasmid to other bacteria during conjugation, a process by which bacteria exchange genetic information. Plasmids have been shown to be instrumental in the transmission of special properties, such as antibiotic drug resistance, resistance to heavy metals, and virulence factors necessary for infection of animal or plant hosts. The ability to insert specific genes into plasmids have made them extremely useful tools in the fields of molecular biology and genetics, specifically in the area of genetic engineering.
Flagella - Flagella (singular, flagellum) are hairlike structures that provide a means of locomotion for those bacteria that have them. They can be found at either or both ends of a bacterium or all over its surface. The flagella beat in a propeller-like motion to help the bacterium move toward nutrients; away from toxic chemicals; or, in the case of the photosynthetic cyanobacteria; toward the light.
Nucleoid - The nucleoid is a region of cytoplasm where the chromosomal DNA is located. It is not a membrane bound nucleus, but simply an area of the cytoplasm where the strands of DNA are found. Most bacteria have a single, circular chromosome that is responsible for replication, although a few species do have two or more. Smaller circular auxiliary DNA strands, called plasmids, are also found in the cytoplasm.
Pili - Many species of bacteria have pili (singular, pilus), small hairlike projections emerging from the outside cell surface. These outgrowths assist the bacteria in attaching to other cells and surfaces, such as teeth, intestines, and rocks. Without pili, many disease-causing bacteria lose their ability to infect because they're unable to attach to host tissue. Specialized pili are used for conjugation, during which two bacteria exchange fragments of plasmid DNA.
Ribosomes - Ribosomes are microscopic "factories" found in all cells, including bacteria. They translate the genetic code from the molecular language of nucleic acid to that of amino acids—the building blocks of proteins. Proteins are the molecules that perform all the functions of cells and living organisms. Bacterial ribosomes are similar to those of eukaryotes, but are smaller and have a slightly different composition and molecular structure. Bacterial ribosomes are never bound to other organelles as they sometimes are (bound to the endoplasmic reticulum) in eukaryotes, but are free-standing structures distributed throughout the cytoplasm. There are sufficient differences between bacterial ribosomes and eukaryotic ribosomes that some antibiotics will inhibit the functioning of bacterial ribosomes, but not a eukaryote's, thus killing bacteria but not the eukaryotic organisms they are infecting.

Does all bacteria look the same?
any websites or books would help! thanks
Does all bacteria look the same?
There are 1000's and 1000's of different kinds of bacteria, and most all of them look different. Check out the link below.
Reply:lotsa different shaped ones - rods, balls, spirals
look in the morphology section here:
http://en.wikipedia.org/wiki/Bacteria
Reply:No that is why we have the study of microbiology. A search of microbiology got me to the below link.
Reply:Oh my, no!
Some are rods, some are spheres, some are footballs, some are curliques.
Reply:No. For example Baccili, Anthrax is one of these, are rod shaped. However, parameciums are shaped like slippers.
Reply:no, they're looks differe from each other... search yahoo!.
Reply:No, they come in several shapes and sizes. The following website may help:

If a bacteria multiplies itself in to two every second.in an hour there are 5M, at what time it reaches 2.5M?
using your rate = 0:59:59
at 1hr they equal 5million so 1sec beforehand they would have numbered 2.5million
At 1:00:01 there would be 10million and so on

59 min 59 sec
Reply:What time did it start?
Reply:59 minutes 59 seconds
Reply:30 minutes
Reply:hour minus one second.
Reply:Yep, I agree with wombat.
Reply:One hour minus one second. In that final second of the hour, the number doubles from 2.5 M to 5 M.
Reply:1 second before that hour
and everyone who doesn't say a second before has officially got an IQ below 80 which is equal to George Bush!!
And certain vegetables can out think him!
Reply:59 minutes and 59 seconds
Reply:1 sec = 1
2 secs = 2
3 secs = 4
4 secs = 8
11 secs = 10
21 secs = 1,048,256
22 secs = 2.096,512
Just over 22 seconds, not minutes at all.
In an hour there with would be billions of billions of billions.
Reply:Use your brain....if there are 5million in 1 hour then 2.5 million would take half an hour!!!!!!!!!!!!!!!!!
How will you ever learn if you do not put some effort to it!
Reply:if you know that much you should know the answer??
Reply:59 min 59 seconds = 2.5M
after 1 sec i.e. 1 hour = 5M
Reply:Actually it occurs between the 22nd and 23rd second providing none die, and 5 million is attained between the 23rd and 24th second.
22 seconds into multiplying the total would be 2,097,152
23 seconds into multiplying the total would be 4,194,304
24 seconds into multiplying the total would be 8,388,608
Reply:they dont multiply every second they can divide every 20 minutes, but thats pretty much the minimum. you answer is roughly 40 minutes i could work it out properly but i dont want to,
according to your figure of 1 sec it would only take 22 seconds to make wel over 2.5 million and 23 seconds to reach 5 million. using the 20 minute figure that i suggested it would take 6 hours 40 minutes to get to 1 million 7 hours to get to 2 million 7 hours 20 minutes to get to 4 million. so im not sure that helps you that much, but i hope it does,

The fastest muliplying bacterium is E.coli which can self-replicate under ideal conditions in 20 minutes using a two-way rolling-circle genome replication technique.
Every two seconds?! I think not!
Reply:It takes one second from the time the 2.5 mil mark is reached.
Reply:time it reaches 2.5m= 60/5
