Some information on the morphology of Cryptocaryon irritans from South-East Queensland, Australia

The morphology of two isolates of the parasitic ciliate Cryptocaryon irritans obtained from wild fish from S-E Queensland, Australia, was examined by observation of live parasites, silver impregnation (protargol, silver carbonate, silver nitrate), scanning (SEM) and transmission (TEM) electron microscopy. Trophonts of both isolates were characterised by an apical cytostome and a post-oral groove readily visible in silver carbonate impregnations...
