How did MRSA evolve?
MRSA is a resistat bacteria that has evolved over time b/c of the misuse of antibiotics. People are eaither not taking antibiotics right, or not finishing the antibiotics they are perscribed. If they don’t finish the perscribed dose the bacteria the medicine is supposed to be killing will develop a resistance to it. So that the next time you are given this medicine it won’t be able to fight off the bacteria.
