Reptile · Pogona vitticeps · typical adult weight 0.38–0.51 kg

11 cited drugs treat Bacterial Infections in bearded dragons: Amoxicillin, Ampicillin, Cefotaxime, Ceftazidime, Ceftiofur, Chloramphenicol, Enrofloxacin, Enrofloxacin Injectable, Oxytetracycline, Trimethoprim-Sulfamethoxazole, Vitamin C (Ascorbic Acid).

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 bearded dragons — a reference list, not new species-specific clinical guidance.
