dorisa dorisa dorisa is a genus of parasitic alveolates in the phylum apicomplexa. dorisa scientific classification domain: eukaryota (unranked): sar (unranked): alveolata phylum: apicomplexa class: conoidasida subclass: coccidiasina order: eucoccidiorida suborder: eimeriorina family: eimeriidae genus: dorisa species dorisa aethiopsaris dorisa arizonensis dorisa bengalensis dorisa chakravartyi dorisa graculae dorisa hareni dorisa harpia dorisa hoarei dorisa indica dorisa mandali dorisa passeries dorisa rayi dorisa vagabundae 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 the species in this genus infect the gastrointestinal wall of vertebrates. description genus diagnosis is dependent on the oocyst: there is a definite cell wall in this genus whereas in dorisiella the oocyst wall is membrane like. host records d. harpia - lesser hairy winged bat (harpiocephalus harpia lasyurus)
