ABSTRACT Normal passerines (n=216) were evaluated for oocysts of Isospora in feces at the Triage Center for Wild Animals (CETAS, IBAMA, Belo Horizonte; August 21 to September 21, 2012). The positive samples with oocysts represented 13.0% of Cardinalidae (n=23), 11.2% of Emberizidae (n=107), 50% of Icteridae (n=10) and 60.3% of Thraupidae (n=68). The probability of fecal oocysts attributable to the host in Thraupidae is higher than in Cardinalidae, Emberizidae, Fringillidae and Turdidae, but similar to Icteridae. No oocysts were found in Fringillidae and Turdidae. Within Thraupidae, Isospora was for the first time described in Paroaria dominicana and Schistochlamys ruficapillus and within Icteridae, in Gnorimopsar chopi. Saltator similis presented a higher risk, 66.9% greater than Lanio pileatus and Sporophila caerulescens and with a 27.9% greater probability than Sporophila nigricolis. The new coccidian species described were Isospora dominicana [ellipsoid oocysts, 25 (30-20) x 25 (28-20) µm] in Paroaria dominicana; Isospora beagai [ovoid oocysts, 28 (32-17) x 25 (29-16) µm] and Isospora ferri [ellipsoid oocysts, 20 (22-16) x 18 (22-15) µm] in Saltator similis; Isospora ruficapillus [spheric to subspherical oocysts, 25 (26-23) x 24 (25-21) µm] in Schistochlamys ruficapillus; and Isospora chopi [spherical to sub-spherical oocysts, 24.5 x 22 (30-20 x 25-20) µm] and Isospora gnorimopsar [sub-spherical to ovoid oocysts, 27 x 23 (32-22 x 28-20) µm] in Gnorimopsar chopi. The morphometry and features were compared with previously described Isospora in passerines. New coccidian species and new passerine hosts are described for Isospora and recommends for constant monitoring during rehabilitation, especially for the hosts of Thraupidae and Icteridae.
