ABSTRACT: This paper describes the first case of bacterial kidney disease (BKD) to be identified in coho salmon Oncorhynchus kisutch in Russia. The fish in question was caught in Lake Bolshoi Vilyui on the Kamchatka Peninsula. The diseased fish had foci of granulomatous inflammation in the kidneys. The diagnosis was confirmed by isolating the bacterium Renibacterium salmoninarum from kidney tissue in pure culture, and by determining the partial 16S RNA gene sequence of the isolate. This is the first detection of this pathogen in the genus Oncorhynchus in Russia, and detection of BKD in coho salmon indicates that the pathogen is present in the natural fish populations of Kamchatka. Therefore, it will be necessary to conduct screening studies of mature salmon selected for artificial reproduction, for the presence of BKD signs and asymptomatic infection with R. salmoninarum, which will allow us to estimate the prevalence of the pathogen.
