Eugregarines and cryptosporidia: peculiar parasites with epicellular development

Popis výsledku v původním jazyce

Gregarines and cryptosporidia are often considered to be peculiar apicomplexans, as they exhibit unique features in their attachment strategy, and some phylogenetic analyses have pointed out their affinity. This study focuses on the ultrastructural analysis of their early development and host-parasite interactions, and searches for explicit characteristics common to both apicomplexans. The formation of attachment site was studied in two eugregarines, Gregarina polymorpha and G. steini from laboratory reared insects, and obtained data were directly compared with comparable features observed during attachment process of Cryptosporidium muris in the stomach of experimentally infected rodents. In both apicomplexans, the apical complexes disappear early during cell invasion and parasites are attached to the host cell by their apical processes, i.e. epimerite in eugregarines and the feeder organelle in cryptosporidia.
