Figures 1–2; Sporulated oocysts of Isospora machadoae sp. nov. recovered from Turdus albicolis from Brazil: (1) line drawing; (2) photomicrographs. Note the micropyle and micropyle cap (m/mc), nucleus (n), polar granule (pg), refractile body (rb), rough oocyst wall (row), Stieda (sb) and sub-Stieda bodies (ssb) and the sporocyst residuum (sr). Scale bar = 10 μm.

Isospora is a genus of internal parasites in the subclass Coccidia.[1][2]

It is responsible for the condition isosporiasis, which causes acute, non-bloody diarrhoea in immunocompromised individuals.

Taxonomy

[edit | edit source]

At least 248 species were originally described in this genus. For instance, the house sparrow has 12 species of Isospora.[1][2] However, most species are little studied, and some authors doubt whether all should be recognized as distinct species.[3] In 2005, all former Isospora species that infect mammalian hosts were reclassified as members of the genus Cystoisospora, a member of the Sarcocystidae family.[4]
