What about bacterial resistance from antibiotic use?

Bacteria mutate: Bacterial resistance occurs when certain antibiotics become ineffective. This can occur in a patient who is being treated with antibiotics or is on antibiotic prophylaxis. Bacteria can mutate, or change so that they have become resistant. Also subjects can deevop an infection from resistant organisms, in which case the "usual" antibiotics will be ineffective requiring more potent antibiotics.

Antibiotics: Bacteria have a remarkable ability to mutate to become resistant to various antibiotics. Bacterial resistance is very real and poses a serious health threat now and probably more so in the future. Antibiotic use needs to be limited and choice of antibiotic specific to the bacteria being treated.
