Vibrio anguillarum is recognized worldwide as a saltwater pathogen in fish.  Most epizootics caused by marine bacteria have been attributed to this organism.   This note describes recent mortalities resulting from vibriosis of Pacific salmon in the marine waters of Puget Sound, Washington, and heterogeneity observed in vibrios isolated from diseased fish. 


The National Marine Fisheries Service (NMFS) is engaged in the experimental culture of Pacific salmon in salt water at the NMFS Aquaculture Experiment Station near Manchester, Washington.  Epizootics caused by marine vibrios have occurred regularly in cultured salmon during the spring and summer months; the organisms were also isolated from diseased fish on a minor scale in every month during fall and winter.  Vibrios originally isolated from diseased fish at Manchester were typical of Vibrio anguillarum ; strain 775 was representative.
