How bacteria resist antimicrobial?

THROUGH THREE WAYS:


EITHER THROUGH


1) a gene mutation in the DNA it self through it will be a major mutation which is called "the major shift".


2)OR through A MUTATION IN WHAT IS CALLED THE "PLASMID". The plasmid shape is circular and carry the resistance factors.This plasmid cause a minor mutation but resistance in major occurs toward the drugs such tetracyclines (or anti-biotics in general). but this occurs upon years. This is known an "the minor drift".


I wish that i hit the point.


3) the conjugation(The sexual bacterial systems).

How bacteria resist antimicrobial?
what ever you throw at them they incorporate in to there make up ,thats why one day flu will kill every one on the planet ,they have been here alot longer than us, and will be here alot longer than us.
Reply:Antibiotic resistance results from gene interaction. Bacteria acquire these gene resistance in a few ways. First, is by way of spontaneous gene mutation - Drug resistant TB arises this way. Second, through microbial sex called conjugation. This is where one bacteria will pass a drug resistant gene to another bacteria by way of a sex pilus. Third, is by their plasmid. This is the most dangerous route as it can become an MRSA (multi-resistant).
Reply:1. Gain additional information, such as resistance cassette (mec for MRSA), plasmid (erythomycine, kanamycin or Cm, etc..), transposon or IS element.


2. mutation, such as linozoid, and others


3. repeat exposural results in activation of multiple drug effux pump, such as Mar
