Dorisa
Dorisa is a genus of parasitic alveolates in the phylum Apicomplexa.

The genus was separated from the genus Dorisiella by Levine in 1908. Dorisiella was created for a parasite infecting a marine polychaete by Ray in 1930. Levine separated off a number of species that while morphologically similar occurred in vertebrates rather that polychaetes.

Life cycle
