Is a snapshot of the complex problem of antibiotic resistance today and the potentially catastrophic consequences of inaction
How do bacteria “become” drug resistant?
When an antibiotic is used, the goal is to wipe out a large percentage of the population, leaving only a few bacteria behind that the body can naturally handle. Up until recently, it was normal practice to prescribe antibiotics as a precaution, even when bacteria were not the agent at hand.
As it turns out, natural mutations in some bacteria make them resistant to certain antibiotics. Since these are the only bacteria to survive the antibiotic use, they also are the only bacteria to split and “reproduce,” meaning that, through basic genetics, each “offspring” bacteria likely also carries that mutation. You see where this is going — eventually, entire bacteria groups are nearly or entirely resistant to the most commonly used antibiotics, and even to more rarely used kinds.
Interestingly, the very existence of “drug-resistant bacteria” is evidence for evolution, and even indirect natural selection!
