Atypical spermiogenesis in a parasitic flatworm, Didymozoon (trematoda: digenea: didymozoidae)

Journal of Ultrastructure Research, 1984
Spermiogenesis in trematodes usually involves the formation in the spermatid of a characteristic structure, a protuberance called the zone of differentiation. This structure was not found in Didymozoon. Instead, spermiogenesis in Didymozoon consists of an elongation of the whole spermatid.

Ultrastructure of Didymocystis semiglobularis (Didymozoidae, Digenea) cysts in the gills of Pacific bluefin tuna (Thunnus orientalis)

Parasitology Research, 2008
Tuna are active pelagic fish with an extraordinary migratory activity, well known for their unique physiology reflected in high metabolic rates. However, knowledge of microbial and environmental diseases is still limited. We have analyzed the ultrastructure of the digenean trematode Didymocystis semiglobularis isolated from the gill arch of Pacific ...
