title: Molecular genetic investigations on Balantidium ctenopharyngodoni Chen, 1955, a parasite of the grass carp (Ctenopharyngodon idella).
abstract: Balantidium ctenopharyngodoni is a common ciliate in Hungary, infecting the hindgut of grass carp (Ctenopharyngodon idella), a cyprinid fish of Chinese origin. Although data have already been presented on its occasional pathogenic effect on the endothelium of the host, generally it is a harmless inhabitant of the gut. Phylogenetic analysis of the 18S rDNA and ITS fragments of this protozoan proved that it is in the closest phylogenetic relationship with endocommensalist and symbiont ciliates of mammals feeding on large volumes of green forage, in a similar way as Balantidium spp. known from algae-eating marine fishes.
