Clinical large intestinal coccidiosis in camels (camelus dromedarius) in the united arab emirates: description of lesions, endogenous stages, and redescription of isospora orlovi, tsygankov, 1950 oocysts. Journal of Parasitology 88:548-552. Interpretive Summary: Parasites of the genus Isospora are single-celled parasites of livestock and humans. Some species of Isospora cause diarrhea in pigs, companion animals and humans. Little is known of Isospora infections in ruminants. Scientists at the Beltsville Agricultural Research Center and the Central Veterinary laboratory in Dubai, United Arab Emirates report for the first time fatal coccidiosis in young camels associated with an Isospora. These results will be of interests to veterinarians, parasitologists and pathologists. Technical Abstract: Between January and March 2001, 8, 4-8 wk-old camels (Camelus dromedarius) from 2 farms from Dubai area of the United Arab Emirates were submitted for necropsy examination. The camels had diarrhea of 2 to 5 days duration. Grossly, a severe diphtheroid to hemorrahigic colitis was seen in all animals. Gamonts, unsporulated oocysts, sporulating oocysts, and fully sporulated oocysts were present in intestinal epithelium and the lamina propria. Fully sporulated oocysts contained 2 sporocysts and 4 sporozoites in each sporocyst. Oocysts from fecal samples resembled oocysts of Isospora orlovi. This is the first report of an isosporan parasite associated with hemorrhagic enteritis in the large intestine of any animal. |
