An epizootic in chinook salmon (Oncorhynchus tshawytscha) caused by a sorbitol-positive serovar 2 strain of Yersinia ruckeri.
Enteric redmouth disease is described in chinook salmon (Oncorhynchus tshawytscha) at a state hatchery in Sand Ridge, Illinois. Biochemical, isoenzyme, and serological data indicated that the epizootic was caused by a sorbitol-fermenting Serovar 2 strain of Yersinia ruckeri. In laboratory experiments the isolate was pathogenic for both brook trout (Salvelinus fontinalis) and Atlantic salmon (Salmo salar).
