Abstract
Three young Arabian sand gazelles (Gazella subgutturosa marica) were each infected with 20,000 sporulated oocysts of Eimeria rheemi collected from a naturally infected rheem gazelle. Both prepatent and patent periods were 7 days and the infected animals consistently passed large numbers of oocysts in their feces during patency. Infection with E. rheemi at this dose was associated with clinical coccidiosis in the form of 2 days of diarrhea before patency, continuing to day 15 postinoculation. The diarrhea stopped without treatment.
