“…The aims of the current review are firstly to assemble the salient information into a single text, which will hopefully serve to facilitate the study of the parasites in question, and secondly to provide an updated scientific basis for the identification of sporulated oöcysts recovered from the faeces of passerine birds in North, Central and South America. Eimeria Schneider, 1875 Species of Eimeria parasitising Passeriformes in the Americas were first described only recently, when Berto et al (2008cBerto et al ( , 2009d described two species from two species of the Tyrannidae in southeastern Brazil. Morphometric data for the sporulated oöcysts of these coccidia are presented in Table 1.…”

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.

ResumenEl gorrión altiplanero o de Worthen (Spizella wortheni) es endémico del altiplano mexicano y debido a su limitada distribución y tamaño poblacional es considerada una especie en peligro de extinción a nivel nacional e internacional. De manera general, las especies en peligro han estado expuestas, al menos históricamente, a una fuerte reducción en su tamaño poblacional y su diversidad genética, factores que en su conjunto aumentan el riesgo y susceptibilidad a infecciones. Por lo tanto, con el propósito de determinar dicha propensión en esta especie, analizamos la prevalencia de parásitos intestinales a partir de muestras fecales en 11 individuos, así como hemoparásitos, hematocrito y cuantificación diferencial de leucocitos a partir una muestra sanguínea. Los resultados mostraron que el 91% de los individuos presentaron por lo menos un taxón de parásitos intestinales, siendo el género Cryptosporidium (64%) el de mayor prevalencia, seguido por Eimeria (55%) y Ascaridia (9%). Sin embargo, los valores medios de oocistos/huevo por gramo de heces fecales indicaron una baja infección parasitaria. Además, no se observaron parásitos sanguíneos y el conteo de células blancas fue similar a lo previamente reportado para otras especies de la familia Emberizidae y Passerellidae.Palabras clave: Gorrión altiplanero, Spizella wortheni, peligro de extinción, parásitos fecales, hemoparásitos, conteo diferencial de leucocitos. AbstractThe Worthen's sparrow is an endemic bird of the Mexican Plateau that due to its limited distribution and population size is considered to be endangered, both nationally and globally. In general, species at risk have been, at least historically, under population size and genetic diversity reductions, which are factors that can act together to increase infections risk and susceptibility. Therefore, with the purpose to determine such propensity in this species, we analyzed the intestinal parasitic infection through fecal samples from 11 individuals, and hemoparasites, hematocrit and differential leukocyte quantification from one sample. Results indicated that 91% of the samples had one parasite taxon, with genus Cryptosporidium showing the highest prevalence (64%), followed by Eimeria (55%), and Ascaridia (9%). However, mean values of oocysts/eggs per gram indicated a low parasitic infection. We found no blood parasites, and the white blood cell counts were among reference values for other sparrow species.

In the current study, two new coccidian species (Protozoa: Apicomplexa: Eimeriidae) obtained from short-crested flycatcher Myiarchus ferox (Gmelin) are reported from Brazil. Isospora feroxis n. sp. has oöcysts which are spheroidal to sub-spheroidal, 18.7 x 18.0 microm, with a smooth and bi-layered wall, c. 1.2 microm. The micropyle and oöcyst residuum are absent, but two polar granules are present. Its sporocysts are broadly ellipsoidal and 11.7 x 8.5 microm. Stieda and substieda bodies are present. A sporocyst residuum is present and the sporozoites have a refractile body and nucleus. Oöcysts of Eimeria sicki n. sp. are spheroidal to sub-spheroidal, 30.3 x 28.5 microm, with a smooth and bi-layered wall, c. 1.3 microm. The micropyle, oöcyst residuum and polar granule are absent. Its sporocysts are ellipsoidal, 18.4 x 10.0 microm. Stieda and substieda bodies are present. A sporocyst residuum is present and sporozoites have a refractile body and nucleus.
