<i>Kudoa thyrsitis</i> (Gilchrist) (Myxosporea: Multivalvulida) in coho salmon, <i>Oncorhynchus kisutch</i> (Walbaum)

Abstract

An unusual case of infection of coho salmon, Oncorhynchus kisutch (Walbaum), in British Columbia, Canada, with a myxosporean Kudoa thyrsitis (Gilchrist) is described. This first report of Kudoa parasitizing a member of the genus Oncorhynchus is interesting also because of the unusual site of Kudoa in the fish, the cardiac muscle.
