Isospora

 [i-sos´po-rah]
a genus of sporozoan parasites (order Coccidia), found in birds, amphibians, reptiles, and various mammals, including humans; I. bel´li is the etiologic agent of coccidiosis in humans. The former species I. ho´minis has been reclassified as two species, Sarcocystis bovihominis and S. suihominis.

Isospora

(ī-sos'pō-ră),
A genus of coccidia (family Eimeriidae, class Sporozoea), with species parasitic chiefly in mammals; the ripe oocysts contain two sporocysts, each of which contains four sporozoites. This genus is now known to be closely related to Toxoplasma and Sarcocystis, with a similar sexual phase in the life cycle and a similar apical complex.

Isospora

/Isos·po·ra/ (i-sos´por-ah) a genus of sporozoan parasites (order Coccidia), found in birds, amphibians, reptiles, and various mammals, including humans; I. bel´li and I. hom´inis cause coccidiosis in humans.

Isospora

[ī·sos′pə·rə]
Etymology: Gk, isos, equal + sporos, seed
a genus of coccidian protozoa found in birds, amphibians, reptiles, and mammals, including humans, that infects the epithelial cells of the small intestine. It is the least common cause of coccidiosis. It includes the species I. belli and I. hominis. See also isosporiasis.

I·sos·po·ra

(ī-sos'pŏr-ă)
A genus of coccidia chiefly parasitizing mammals.

Isospora

a genus of apicomplexan parasites in the family Eimeriidae found mainly in dogs and cats. These protozoa develop intracellularly in the cells of the intestinal epithelium and some of them are associated with attacks of diarrhea. Includes I. almaataensis (pigs), I. bahiensis (dogs), I. bigemina (Cystoisospora burrowsi), I. burrowsi (C. burrowsi), I. buteonis (raptor birds), I. canis (C. canis), I. felis (C. felis), I. heydoni (C. heydoni), I. neorivolta (dog), I. ohioensis (C. ohioensis), I. ratti (rats), I. rivolta (C. rivolta), I. suis (pigs), I. wallacei (Besnoitia wallacei).

Results: Intestinal parasitic pathogens were detected in 35 per cent patients, and the major pathogens included Cryptosporidium parvum (12%) the most common followed by Isospora belli (8%), Entamoeba histolytica/Enatmoeba dispar (7%), Microsporidia (1%) and Cyclospora (0.
