Název v původním jazyce

Ultrastructure of oocysts and sporozoites of urosporid gregarine from marine polychaete

Popis výsledku v původním jazyce

Apicomplexans represent a very successful group of unicellular parasites that consists entirely of parasitic species infecting a wide range of vertebrates and invertebrates. Gregarines represent a basal group of the phylum Apicomplexa. The life cycle of eugregarines is in general characterised by a lack of merogony (asexual reproduction for autoinfection), but a presence of syzygy (pregamic paired association of gamonts) and gametocyst stage. Within gametocyst, gametogony (sexual reproduction), fusion of gametes and sporogony (formation of invasive stages) take place. The crucial step for parasite dissemination and effective infection of new hosts is formation of sporozoites within a protective envelope during the sporogony. The knowledge of the morphology of these stages can provide a possible evolutionary pathways particularly within gregarines and apicomplexans in general. In the body cavity of polychaete Travisia forbesii brown bodies comprising white spheres were found.
