6
Q
Explain how microbes can be resistant to antimicrobials?
A
- Organisms will develop random mutations in their DNA. And this is the same with bacteria. For example being resistant to antibiotics.
- When bacteria reproduce there will be random mutations but there will only be one bacterium with this gene.
- When we use antibiotics this will kill all the non-resistant bacteria and only leave the resistant one.
- This then allows the resistant bacterium to reproduce and there will be bacteria that will be resistant. This will become more common in a population of bacteria over a long period of time.
