摘要
Resting spores of Ichthyophonus hoferi (50-230 mu m in diameter) were found in the kidney, heart, liver, skeletalal muscles, exocrine pancreas, and connective and fatty tissues of young coho salmon Oncorhynchus kisutch from the Vilyuisky fish hatchery. In 10% of the fish, there were granulomas and giant cells in these organs. This is the first report of Ichthyophonus infection in Kamchatka.
