Am I better yet? You're over your strep throat and feeling well again, so is it time to ditch the antibiotics? Well, you could, but evolutionary biology suggests that stopping a course of antibiotics early encourages the evolution of antibiotic resistant bacteria, by allowing those bacteria not quite killed off by the incomplete dose of antibiotics to preferentially survive and reproduce. Those mildly resistant bacteria could come back to haunt you or infect someone else, and if they do, your original antibiotic may not work against the new strain. |
