Název v původním jazyce

Gametocyst and oocysts morphology of Urospora travisiae, an extraordinary eugregarine from marine polychaete

Popis výsledku v původním jazyce

Apicomplexans represent successful group of unicellular parasites of vertebrates and invertebrates. They possess complicated life cycle, with sporogony, merogony and gametogony. The LC of eugregarines is characterized by a lack of merogony, but a presence of syzygy and gametocyst. Inside the gametocyst gametogony, fusion of gametes and sporogony take place. Way of gametocyst excystation and oocyst morphology are considered as key features in gregarine taxonomy, few detailed studies on terrestrial and marine gregarine species dealing with their architecture exist. We present new data on morphology of gametocysts and oocysts found in marine polychaete Travisia forbesii. In body cavity brown bodies comprising gametocysts of Urospora travisiae were found.Gametocysts, whitish, round in shape surrounded with flattened coelomocytes. Envelope is thick and consists of numerous layers and hyaline cover. Under envelope, oocysts can be observed using light or electron microscopy.
