[Cholecystitis and cholelithiasis induced by lincomycin. Microscopic and ultrastructural studies].

Gallbladder of 30 golden hamsters was evaluated after a seven days course of lincomycin (60 mg/kg/day). Fifteen animals injected with an equivalent volume of saline and 15 animals non injected at all, were used as controls. Weight, sex, age, and food were similar in all groups. Eight hamsters (23%) treated with lincomycin formed pigmented gallstones.
