Leptospirosis in a dog with uveitis and presumed cholecystitis.

A 7 yr old castrated male Australian shepherd dog was examined for acute change in iris color, lethargy, and anorexia. Uveitis, acute renal failure, and presumed cholecystitis were diagnosed. Based on clinical findings, leptosporosis was suspected, and the dog was treated with antibiotics and supportive care. The dog made a complete recovery, and leptospirosis was confirmed on convalescent titers. Due to the zoonotic potential, leptospirosis should be considered in cases of uveitis, as well as possible cholecystitis.
