“…From previous descriptions, I. sicalisi presents oocysts with similar dimensions to the oocysts described by McQuistion and Wilson (1988), McQuistion (1990), Ball and Daszak (1997), and Pereira et al (2011 Pereira, Berto, Flausino, Lovato et Lopes, 2011 has SB half-moon-shaped and SR compact. These last characteristics were not found in I. sicalisi (Table I).…”

Two new coccidian species (Protozoa, Apicomplexa, Eimeriidae) are reported from the saffron finch Sicalis flaveola Linnaeus, 1766, a very common species in South America. Isospora cetasiensis sp. nov. oocysts are subspherical to ellipsoidal, 23.1 × 21.6 µm, with smooth, bilayered wall, ~1.0 μm. Micropyle, oocyst residuum and polar granule are absent. Sporocysts are ovoidal, 15.1 × 10.9 μm. Stieda body is knob-like and substieda body is rounded. Sporocyst residuum is composed of many scattered granules and spherules of different sizes. Sporozoites are vermiform with one refractile body and a nucleus. Isospora sicalisi sp. nov. oocysts are subspherical to ellipsoidal, 27.5 × 25.2 μm, with a smooth, bilayered wall, ~1.1 μm. Micropyle, oocyst residuum and polar granule are absent. Sporocysts are ellipsoidal, 17.2 × 11.7 μm. Stieda body is knob-like and substieda body is trapezoidal. Sporocyst residuum is composed of scattered granules and spherules of different sizes. Sporozoites are vermiform with one refractile body and a nucleus.

“…In the fecal samples, 55.5% of the samples were negative, and in 44.5% oocysts of Isospora bocamontensis (Pereira et al 2011) were found, and the infection intensity found is given in Table 1. No other parasite was found in the samples examined.…”

“…The occurrence of Isospora in passerines of the family Emberezidae has been reported worldwide (Pereira et al 2011). Coccidiosis is reported both in captive birds and in free-living birds (Santos et al 2008, Lindström et al 2009, and the prevalence of infection in free--living passerines can reach 100% of the birds (Schwalbach 1960).…”

“…When found coccidia, the portion set apart was placed in a thin layer of a solution of 2.5% of potassium dichromate (K 2 Cr 2 O 7 ) and incubated for 10 days or until 70% of the oocysts became sporulated. The sporulated oocysts were recovered using the Willis-Mollay technique described above, and the oocysts were examined under an optical microscope and compared the morphological and morphometric characteristics with data from literature for identification (Carvalho-Filho et al 2005, Pereira et al 2011.…”

Isospora bocamontensis (Protozoa: Apicomplexa) in captive yellow cardinal Gubernatrix cristata (Passeriformes: Emberezidae)

The yellow cardinal (Gubernatrix cristata) is a passerine found in southern Brazil, especially along the border with Uruguay and Argentina. It is an endangered species and its population is decreasing. Among the parasites that affect passerines, the genus Isospora is the most easily found in both captive and free-living birds. This parasite commonly causes injury to the intestinal tissue and could occasionally affect other organs. In this work we examined the occurrence of coccidiosis in captive yellow cardinals and its association with factors such as sex, use of parasiticides, type of enclosure, contact with feces, type of food and cleaning frequency. We collected fecal samples of 45 yellow cardinals, healthy and kept in captivity, in late afternoon at the end of the reproductive period. The examination showed parasitic infection by Isospora bocamontensis in 44.5% of the birds. This infection is not influenced by the sex of birds, but is significantly affected by the type of enclosure, contact with the feces, use of parasiticides, type of food and cleaning frequency. The results indicate that to keep yellow cardinals captive, these factors must be observed. 4 Departamento de Estatística, UFSM, Av. Roraima 1000, Santa Maria, RS.

Comumente causam injúrias no tecido intestinal, podendo ocasionalmente afetar outros órgãos. Neste trabalho examinamos a ocorrência de coccidiose em cardeais mantidos em cativeiro e verificamos sua associação com fatores como sexo, uso de produtos parasiticidas, tipo de recinto, contato com fezes, tipo de alimentação e frequência de limpeza. Foram coletadas amostras de fezes, ao entardecer, de 45 cardeais-amarelos, hígidos, mantidos em cativeiro, no final do período reprodutivo. O exame coproparasitológico revelou infecção parasitária por Isospora bocamontensis, em 44,5% das aves. Esta infecção não é influenciada pelo sexo das aves, mas é significativamente afetada pelo tipo de recinto, contato com as fezes, uso de parasiticidas, tipo de alimentação e frequência de limpeza. Indicando que para a manutenção em cativeiro estes fatores devem ser observados.

In the New World, the avian order Passeriformes comprises 47 families and 2,453 species, yet to date only 21 (45%) of the families and 58 (2%) of the species have been examined for coccidia, and from these only two species of Eimeria Schneider, 1875 and 81 species of Isospora Schneider, 1881 have been described. This review contributes to our understanding of the morphology and systematics of coccidian parasites of passeriforms, providing a scientific basis for the identification of sporulated oöcysts recovered from the faeces of passerine birds from North, Central and South America. To this end, the coccidia were organised and grouped according to the family of the host, following the widely recognised concept of family-specificity and the updated systematics of the class Aves. Details of 83 eimeriid species are presented along with an illustration and tabulated data.
