The Myxozoa are a group of parasitic organisms of fish, and rarely in amphibians and reptiles in aquatic environments. Over 1500 species have been described and many have a two-host lifecycle, involving a vertebrate and an annelid worm or a bryozoan.  Infection occurs through valved spores. Our work on amphibian myxozoans is conducted with the collaboration of Dr. Christopher Whipps and Miloslav Jirků.  We are currently describing and re-describing new species of amphibian myxozoans and constructing molecular phylogenies of these parasites. We are currently beginning life cycle studies on these parasites.
