Levineia Dubey, 1977 Cystoisospora is a genus of parasitic alveolates belonging to the phylum Apicomplexa.

[2] This genus currently includes species that have oocysts containing two sporocysts with four sporozoites in each without Stieda bodies.

These parasites normally infect the enterocytes of the small intestine and are spread by the orofaecal route.

[5] Clinical signs include watery diarrhea, vomiting, fever and weight loss.

Utensils, runs, cages and other implements should be steam-cleaned or washed in boiling water.
