Some 25 spores of Myxidium sp. were found out in an “Ich” Ichthyophthirius multifilis parasitic to the skin of a young cultured Euro pen eel Anguilla anguilla. The host eel was observed to be infested with not only a number of “Ich”s but also Myxidiian spores in the skin.
Two other “Ich”s were found out which carried in their body digested Myxidiian spores. A few Myxidiian spores were found in the surface layer of the dermis just beneath one of the “Ich”s.
These Myxidiian spores found in the “Ich”, seem to be taken by the ciliate while they were coming out from the surface of the dermis in the skin of the host.
(The present author observed that matured spores of the present Myxidium come out from the skin of living eels. The detail will be reported elsewhere.)
