“…This bird has often been investigated for ecto and endoparasites, since the species is adapted either to wild or urban environmental conditions, commonly sharing food with sparrows and pigeons in the cities, in residential areas and mainly in the vicinities of pet shops, where captive exotic birds and small rodents are maintained for sale; thus, with the possibility of acting as reservoirs and carriers of pathogenic agents mainly to Galliformes hosts from backyard flocks or other avian hosts of economic importance, specimens of C. talpacoti are referred in surveys of acari ( Arzua and BarrosBattesti, 1999;Price et al, 1999) protozoa (Adriano et al, 2000;Adriano and Cordeiro, 2001 ) viruses (Ferreira et al;1994;Pereira et al, 2001) and helminths, that are the main target of this investigation.…”

This is the first report of the digenetic trematode Paratanaisia bragai infestation in a ruddy ground dove Columbina talpacoti, captured in a suburban area of Rio de Janeiro, Brazil. Although with a low prevalence (10%), the intensity of infection was high, considering that 116 worms were recovered from one of the kidneys. Gross lesions were not observed and histopathological analysis showed very dilated renal collecting ducts with destruction and flattening of the lining epithelial cells, without inflammatory reaction. The pathological findings were compared to those previously reported for P. bragai in other hosts, since the proposal of the species in 1934.

“…Both species were positive for Eimeria. One specimen of C. talpacoti that was caught shed oocysts with morphology identical to that described for Eimeria curvata Adriano, Thyssen, Cordeiro, 2000. This species was originally described from specimens of C. talpacoti and Columbina squammata (Lesson, 1831) that were caught in the municipality of Junqueirópolis, in the west of the state of São Paulo, Brazil (ADRIANO et al, 2000).…”

Coccidia are protozoan parasites that are frequently observed in fecal samples from wild birds, and they are extremely important for biodiversity, host specificity and conservation. The aim of the present study was to identify and quantify the coccidian species from wild birds caught in a fragmented area of Atlantic Forest in the municipality of Guapimirim in the state of Rio de Janeiro, which is located around the Serra dos Órgãos National Park. A total of 101 birds were caught and identified. The highest prevalence and density were observed in the family Columbidae (Columbiformes). Among the families of Passeriformes, the highest prevalences and densities were of birds in the families Thraupidae and Turdidae. The majority of the positive samples and those with higher densities were collected in the afternoons. Eleven coccidian species of Isospora and Eimeria were identified. Seven of these species that were morphologically identified are undescribed in the scientific literature and are believed to be new species. The present study highlights the wide distribution and dispersion of coccidia of wild birds in southeastern Brazil, and records the municipality of Guapimirim, in the state of Rio de Janeiro, as a new locality for parasitism, along with the new hosts recorded.Keywords: Oocysts, morphology, taxonomy, prevalence, density, Parque Nacional da Serra dos Órgãos. ResumoOs coccídios são protozoários parasitas frequentemente observados em amostras fecais de aves silvestres, os quais têm extrema importância para a biodiversidade, especificidade hospedeira e conservação. O presente estudo teve como objetivo identificar e quantificar as espécies de coccídios de aves silvestres capturadas em uma área fragmentada de Mata Atlântica no município de Guapimirim, Estado do Rio de Janeiro, que está localizada no entorno do Parque Nacional da Serra dos Órgãos. Foram capturadas e identificadas 101 aves. A maior prevalência e densidades foram observadas na família Columbidae (Columbiformes). Nas famílias de Passeriformes, as maiores prevalências e densidades foram de aves das famílias Thraupidae e Turdidae. A maioria das amostras positivas e com maiores densidades foram coletadas no período da tarde. Foram identificadas onze espécies de Eimeria e Isospora. Sete dessas espécies morfologicamente identificadas não estão descritas na literatura científica e devem ser novas espécies. O presente trabalho expõe a ampla distribuição e dispersão de coccídios de aves silvestres no sudeste do Brasil e registra o município de Guapimirim, no estado do Rio de Janeiro, como uma nova localidade de parasitismo, além dos novos hospedeiros registrados.

The aim of the present study was to detect Eimeria spp. in eared doves (Zenaida auriculata) from Brazil. Two hundred and fourteen birds were trap-capture in different regions of Londrina city, Paraná state, Southern Brazil. Fecal samples were collected, and DNA extraction was performed. A nested PCR based on the subunit I of the cytochrome c oxidase gene of the Eimeria mitochondrial genome was used to detect the DNA presence of this coccidian in eared dove feces. From 214 birds, 171 (79.9%) were positive for Eimeria spp. There was significantly difference of positivity between the site of capture. When analyzing the genders, the numbers of positive males were 84/103 (81.5%) and females 87/111 (78.4%). To the best of the authors’ knowledge, this is the first study with molecular prevalence of Eimeria sp. in Z. auriculata. Further studies should be done to identify the species of Eimeria that infect eared doves Z. auriculata.
