Infectious necrotic hepatitis caused by an unclassified anaerobic bacillus in the water snake.
Necrotic hepatitis resembling black disease of ruminants is described in a group of five water snakes (Natrix sipedon pictiventirs). Lesions varied from multifocal granulomas to massive coagulation necrosis. A bacterium recovered from the livers could not be classified, but closely resembled Eubacterium tarantellus. The bacterium was isolated from all snake livers and from snake mites (Ophionyssus natricis) which were probably implicated in the transmission of the disease and it is possible that trematodes were concerned in producing the initial damage to the liver.
