Isospora canaria
Box,
1975
(Protozoa, Apicomplexa, Eimeriidae) is reported and described from canaries
Serinus canaria
(Linnaeus) in southeast Brazil. Its oöcysts are subspheroidal to ellipsoidal, 24.4 × 22.2 μm, with smooth, bilayered wall, ~1.2 μm. The micropyle and the oöcyst residuum are absent, but a polar granule is present. The sporocysts are lemon-shaped, 17.6 × 10.6 μm. The Stieda body is nipple-like, and substieda body is prominent and homogeneous. The sporocyst residuum is composed of scattered granules. The sporozoite has anterior and posterior refractile bodies and a nucleus. The report of this coccidium recovered from exotic canaries in South America is relevant to native passerines, mainly to
Carduelis yarrellii
, which are listed as vulnerable species by IUCN (International Union for Conservation of Nature and Natural Resources).
