Ellipsoidal-shaped spores with two polar capsules were detected in leather carp (Cyprinus carpio nudus) muscle. 18S rDNA gene analysis of the spore showed a 99.58% match to Myxobolus artus, a myxozoan parasite. As a result of phylogenetic analysis using the Bayesian inference model and maximum likelihood model among other Myxobolus species, the isolate in the present study belonged to the M. artus cluster. This is the first case report of M. artus infection detected in domestic aquaculture organisms in Korea.
