Sprozoans (Apicomplexa, Sporozoa) and their hyperparasites
One of our main interests is to uncover the biodiversity of sporozoans (Apicomplexa, Sporozoa). We want to demonstrate attachment and/or invasion strategies of these parasites, to correlate their cell motility with their cell cortex organization and to understand host-parasite interactions deeply. In general, our studies deal with sporozoans from marine invertebrates. We also pay great attention to microsporidia of the family Metchnikovellidae, hyperparasites of many gregarines from marine invertebrates. Metchnikovellides are often considered as a ‘key group’ for understanding the evolution and phylogeny of microsporidia as a whole.
