3.33 Antibiotic resistance

Notes


Antibiotic resistance = increase in population of new allele

*see 3.31 evolution for details on MSSA/MRSA

MSSA --- random mutation (evolution) = MRSA---- process of natural selection ---> MRSA

As antibiotics used over time 
-> MSSA: less common

-> MRSA: more common (resists antibiotic = population expands as normal) / antibiotic no longer 'works'
