Genetic mutations may occur in a bacteria which makes it resistant to an antibiotic. When the antibiotic is used, it leads to natural selection of the bacteria ... Bacteria, Antibiotics, and Other... · Bacteria · Antibiotics

2 июн. 2022 г. · Bacteria evolve rapidly as they reproduce quickly and acquire random mutations – some of which confer resistance.

7 нояб. 2023 г. · Resistance arises when bacteria are exposed to levels of antibiotics that don't immediately kill them. They develop defences that prevent the same antibiotic ...

Through mutation and selection, bacteria can develop defense mechanisms against antibiotics. For example, some bacteria have developed biochemical “pumps” that ...

28 авг. 2017 г. · There are two main ways that bacterial cells can acquire antibiotic resistance. One is through mutations that occur in the DNA of the cell during replication.

Antibiotic resistance has to be gained by a bacterium through the mutation of a gene. This can occur due to, for example, the overuse of antibiotics.

Because of the widespread use (and misuse) of antibiotics, and the rapid evolution of bacteria, resistant strains have emerged such as MRSA (Methicillin- ...
