“…In addition, another consequence is the introduction of new parasites, as occurred with Isospora vanriperorum Levine, 1982, first described from the northern cardinal Cardinalis cardinalis L., 1758, but which due to its introduction into South America for breeding in captivity, was subsequently reported from S. similis (LOPES et al, 2007;BERTO et al, 2011b). The ease of transmission of Isospora among birds from the same family, the large number of cardinalid species in New World and the illegal bird trade may serve to ensure a wide distribution of these parasites in South, Central and North America .…”

Diurnal periodicity is a phenomenon that has been observed in coccidian of Isospora parasites of passerines, which have been eliminated great number of oocysts at dusk. The objective of this study was to evaluate the occurrence of periodicity of oocysts presence in the green-winged-saltator Saltator similis, and its use in the diagnosis of coccidiosis in wild birds in captivity. A total of 220 fecal samples were collected from birds, apprehended from illegal trading and kept in quarantine in CETAS∕IBAMA, in the morning and late afternoon, from May to November 2010. It was observed that 1.82% of the samples collected in the morning were positive, while 31.36% of samples were positive in the late afternoon. In addition, the number of oocysts shed was greater in the afternoon. Therefore, it was concluded that the sampling in the late afternoon provided greater reliability for the diagnosis of coccidiosis in green-winged-saltators. Moreover, in this study a new isosporoid coccidian parasite from the green-winged-saltator S. similis was observed and is herein described. Isospora similisi n. sp. oocysts are spheroidal to sub-spheroidal, 27.5 × 25.9 µm, with a smooth and bi-layered wall, ∼1.2 mm. Micropyle and oocyst residuum are absent, but splinter-like or comma-like granules are present. Sporocysts are ellipsoidal or slightly ovoidal, 17.4 × 12.2 mm. A stieda body and substieda body are present. The sporocyst residuum is composed of granules of different sizes. Sporozoites are vermiform with a single refractile body and a nucleus. This is the fourth description of an isosporoid coccidium infecting S. similis and the sixth description from Cardinalidae.

“…However, it was subsequently renamed I. vanriperorum by Levine (1982b), since the name I. cardinalis had previously been ascribed to the coccidium parasite of an extinct passerine, Lophospingus pusillus, described in East Germany by Gottschalk (1972). Lopes et al (2007) recovered oöcysts, which they considered identical to those of I. vanriperorum, from the green-winged saltator Saltator similis in Brazil (Table 5). According to Carvalho (2009), it is possible that cross-transmission to a second genus in the family took place following the introduction of northern cardinals into South America for captive breeding purposes.…”

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.

“…Isospora dominicana, I. beagai, I. ferri and I. ruficapillus, which were found in the Thraupidae feces, were compared to and differed from I. vanriperorum (Levine et al, 1980;Lopes et al, 2007), I. paroariae (Upton et al, 1985), I. pityli and I. formarum (McQuistion and Capparella, 1992), I. saltatori (Berto et al 2008b), I. trincaferri, (Berto et al, 2008b), I. thraupis (Lainson, 1994;Berto, 2010), I. andesensis (Templar et al, 2004;Berto, 2010), I. irisidornisi (Metzelaars et al, 2005;Berto, 2010), I. tiesangui (Berto et al, 2008a;Berto, 2010), I. marambaiensis (Berto et al 2008a;2010), I. sepetibensis (Berto et al, 2008a;2010), I. cadimi (Berto et al, 2009a;2010), I. navarroi 2010), I. ramphoceli (Berto et al, 2010), I. sanhaci (Berto et al, 2009c;2010), I. silvasouzai (Berto et al, 2009c;2010), I. sayacae (Berto et al, 2009c;2010) and I. similisi (Coelho et al, 2013).…”

“…Considering the sporocyst residuum, a compact residuum similar to I. vanriperorum and I. sepetibensis was observed. In order to compare the species described here to the previously described I. vanriperorum, data in Table II along with descriptive images previously published, were employed (Lopes et al, 2007;Berto et al, 2011a;2011b). Dissimilarities were found when compared to I. vanriperorum, such as a bilayered wall and a large and conspicuous substieda body.…”

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. Coccidiosis in the order Passeriformes is caused mostly by the genus
