How can bacteria become resistant to a bacteriaphage?

Survival can develop based on how the phage invades the cell.





Some bacteriophage adhere to type four pili (TFP), which are projections that extend and retract from bacteria surfaces. Phage can bind to those and are drawn into the cell. A mutation in a cell that results in a changed structure, or lack of function, in TFP would render them resistant to that particular phage.





Other phage, such as lambda, have evolved to bind to various receptors the bacterial cell produces. Lambda binds to the maltose receptor, for example. Therefor, if there is a mutation in a bacterial cell that results in a nonfuctional receptor, or represses expression, or causes a mutation in the structure of the receptor phage that recognize that receptor wouldn't be able to invade the cell either.





Thats a couple of answers, there are more possibilities but that should help you along.

How can bacteria become resistant to a bacteriaphage?
it is somewhat related to the survival extinct like if in given culture or any place there is many type of same kind of bacteria I mean produced by different sources then those bacteria will only survive who had the genetic code to survive during attack of any bacteriophage and thus after sometime those kind will only survive thus producing a resistant


I will give u one more example of this kind like u know cockroaches now they are getting resistant to different sprays we use its the same phenomenon in the group of those cockroaches there are many kinds and the best survives and produces resistant to it.
