Sensitivity to antibiotics
Guinea pigs as a group are unusually sensitive to certain antibiotics, whether they are given orally or by injection. Potentially harmful antibiotics include ampicillin, penicillin, bacitracin, erythromycin, lincomycin, gentamicin, clindamycin, streptomycin, vancomycin and sometimes tetracycline. Interestingly, even certain antibiotics used topically may produce lethal effects.
