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 ).
