Microsporidia of Branchiopods from the Northern Regions of Ukraine
RESUMO
Four species of Microsporidia parasitizing Branchiopod hosts are described based on the light and ultrastructural data. Microsporidium sp. from the body cavity of Lepidurus apus, produced ovoid spores 3.5±0.4ґ2.2±0.3 mm in size. Mononuclear (asymmetrical spores of Larssonia hiberna sp. n., measured 3.8±0.1x2.0±0.2 mm, were found in fat tissues and hemocoel of Daphnia magna. Filamentous episporal surfacing inverted polaroplast and 8-9 coiled isofilar polar filament are characteristic features of this species. Berwaldia singularis Larsson and Microsporidium stagnalis sp. n. from D. pulex are presented. Ellipsoidal spores of M. stagnalis, 4.8±0.4ґ2.4±0.3 mm in sizes, formed a two-layered exospore, tripartite lamellar and tubular polaroplast, and the isofilar polar filament coiled in a two-layer spiral of 14 rings.
