Evidence for Evolution-Resistant Bacteria

Cards (6)

How can bacteria be treated
Antibiotics like penicillin kill bacteria, bacteria evolves extremely rapidly
It can also be used in farming to stop animals developing bacterial diseases
What's an example of an antibiotic resistant bacteria
MRSA
What is the first stage of how antibiotic resistance bacteria occur
In a bacteria population, genetic variation caused by a mutation could make bacterium resistant to antibiotics.Using an antibiotic means all the bacteria is killed apart from the bacteria is resistant to antibiotics
What is the second stage of how antibiotic resistance bacteria occur
These resistant bacteria survive and then reproduce without any competition from other bacteria. This resistant population then rises and the resistant strain now spreads because people aren't immune to it and there's no effective treatment
What are the three ways we can reduces resistant bacteria
Doctors shouldn't prescribe antibiotics innapropriately like for a virus
Patients should be certain to follow their course of antibiotics, meaning all bacteria is killed for certain
Restrict use of antibiotics in farming
Why can't we develop new antibiotics to fight this resistant bacteria
It creates a long time to develop meaning we can't keep up with the bacteria and it is expensive
