Nematopsis

Nematopsis (Nee-mah-top-cis) is a genus gregarine Apicomplexan of the family Porosporidae.[1][2] It is an aquatic parasite of crustaceans with a molluscan intermediate host. Nematopsis has been distinguished from the similar genus Porospora by its resistant and encapsulated oocyst.[3] Little molecular biology has been performed on the members of the Nemaptosis and species are described based on molluscan and crustacean hosts as well as oocyst structure. A total of 38 species have been described and are found all over the world (United States, India, Brazil, Spain, Thailand and other coastal regions)[4][5][2][6][7]
