Gross and microscopic pathology associated with large cavernous lesions in muscle of Chinook salmon from Lake Ontario



Gross and microscopic pathology associated with large cavernous lesions in muscle of Chinook salmon from Lake Ontario



Journal of Wildlife Diseases 43(1): 111-115



Since 1999, eight adult Chinook salmon (Onchorhynchus tshawytscha) from Lake Ontario with large, focal, cavernous, fluid-filled muscle lesions have been examined in our respective laboratories. Gross and microscopic examination, cytology, and bacteriology were performed. Microscopically the lesions were consistent with chronic abscesses. Cytologic evaluation revealed diplomonad flagellate Spironucleus within these lesions. We provide a description of the gross and microscopic pathology associated with the cavernous lesions.
