Hepatic microsporidia were investigated from 5 species of fish, namely Taurulus bubalis (Euphr.), Crenilabrus melops, (L.), Gaidropsarus mediterraneus (L.), Ciliata mustela (L.). and Scophthalmus maximus (L.) and intramuscular microsporidia from 2 species, namely Taurulus bubalis and Cottus gobio L. Detailed ultrastructural studies carried out on hepatic microsporidia from T. bubalis showed it to be a new species belonging to the genus Microgemma (Ralphs) and it is named here as Microgemma dunkerli sp. n. Although hepatic microsporidia from the other species of fish are included in Microgemma, insufficient data was available to determine whether these were synonomous with M. dunkerli or a separate species. Intramuscular microsporidia were identified as Pleistohora sp. and Pleistophora vermiformis (Leger) from T. bubalis and C. gobio respectively. Unsuccessful attempts were made to experimentally transmit spores by per os and intraperitoneal injection using a variety of experimental hosts. Viability studies ...
