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.

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).
