How can I tell what antibiotic to use based on a bacterias sensitivity/resistance? This sounds like a silly question but, if a bacteria is more sensitive to an antibiotic then that would be the right antibiotic to treat it, correct?
The vet would take a sample of the bacteria, then make up a culture from it...then they would try many diffierent antibiotics to see which one the bacteria is sensitive to. You yourself wouldn't know. There are broad spectrum antibiotics which most vets start off with to see if they work (baytril, etc).
