What do antibiotics do exactly and why do people grow resistant to them?
In: Biology
Antibiotics kill bacteria. Bacteria mutate and adapt to their environments (see evolutionary theory) so exposure that does not kill peripheral bacteria can result in mutations that make that bacteria more resistant to the antibiotic.
Hence people should be washing their hands with soap (surfactant to slough and rinse away bacteria) and minimizing the use of hand sanitizer, I think, but someone correct me if this inference is incorrect.
