Bacterial Infections in Ferrets

Pocket Pet · Mustela putorius furo · typical adult weight 0.60–2.00 kg

16 cited drugs treat Bacterial Infections in ferrets: Amoxicillin, Ampicillin, Cefadroxil, Cefovecin, Cephalexin, Ciprofloxacin, Cloxacillin, Erythromycin, Gentamicin, Lincomycin, Neomycin, Oxytetracycline, Penicillin G, Sulfadimethoxine, Tetracycline, Tylosin.

General coverage of susceptible bacterial pathogens. Drug selection turns on the suspected organism's gram-stain, the patient's species (oral β-lactams unsafe in rabbits/guinea pigs), and the infection site (penetration to bone, CSF, or biliary tree).

The overview above describes Bacterial Infections across species; the citations below are the ExoticRx dose rules scoped to ferrets — a reference list, not new species-specific clinical guidance.
