Morphological and molecular characterization of Haemoproteus coatneyi and Haemoproteus erythrogravidus (Haemosporida: Haemoproteidae) in Passeriformes in Brazils Atlantic Forest

Abstract Haemoproteus spp. are protozoan parasites found in birds around the world. These parasites are identified through the morphology of gametocytes, phylogenetic analysis based on the mitochondrial cytb gene, and the parasite's geographic distribution. The absence of erythrocytic merogony, high intr...

First report of Davaneidae and Strongylida parasitizing Ramphocelus carbo (Aves: Passeriformes: Thraupidae) in the southwest of the Brazilian Amazon region

Abstract In Brazil, species of the genus Ramphocelus with the presence of various endoparasites have already been reported. Coccidia have been the parasites most frequently found. All species of this genus have similar habitats and ecological niches, which makes parasite transmission easy. The aim of thi...

Parasites of the Shiny Cowbird, Molothrus bonariensis, and the Austral Blackbird, Curaeus curaeus, (Passeriformes: Icteridae) in Chile

Abstract Comparative studies of parasites in sympatric bird species have been generally scarce. Parasitic infection/transmission can be spread in a number of ways that suggests possible direct and indirect, horizontal transmission between avian hosts. In order to determine whether two sympatric icterids ...

Parasitism of the nasal mite Sternostoma tracheacolum Lawrence, 1948 (Mesostigmata: Rhinonyssidae) in captive birds in Brazil

Abstract Nasal mites (Mesostigmata: Rhinonyssidae) are obligatory endoparasites of birds, and the resulting parasitism can be harmful to the host's respiratory system. The nasal mite Sternostoma tracheacolum Lawrence has caused significant respiratory issues, including serious injuries that possibly caus...

Blankaartia sinnamaryi (Trombidiformes: Trombiculidae) parasitizing birds in southeastern Brazil, with notes on Rickettsia detection

Abstract The larvae of the family Trombiculidae are ectoparasites of vertebrates, including birds. The bite of some species can cause deep lesions and severe skin reactions in the host, these can lead to dermatitis, popularly known as trombiculiasis. A morphological study of chiggers collected on birds ...

Isospora albicollis (Apicomplexa: Eimeriidae) in thrushes Turdus spp. (Passeriformes: Turdidae), in southeastern Brazil

Abstract The aim of the present study was to report and describe Isospora albicollis Lainson and Shaw, 1989 parasitizing a white-necked thrush Turdus albicollis Vieillot, 1818 and a pale-breasted thrush Turdus leucomelas Vieillot, 1818 in two different localities: the Itatiaia National Park and Cacaria, ...

Ectoparasites of the black-chinned siskin Spinus barbatus (Passeriformes: Fringillidae) in Chile

Abstract Despite being a bird with a broad and extensive distribution in Chile, the black-chinned siskin, Spinus barbatus Molina, 1782 is not well studied in relation to its parasites. This paper aims to describe the ectoparasite fauna of S. barbatus in central and southern Chile. A total of 125 individu...

Helminths of Molothrus bonariensis (Gmelin, 1789) (Passeriformes: Icteridae) from southernmost Brazil

Abstract Information about helminths of Molothrus bonariensis (Gmelin, 1789) (Passeriformes: Icteridae) are scarce; in this sense the objective of this paper was to contribute to its knowledge. Five hosts of southern Brazil were examined and the helminths Prosthogonimus ovatus, Tanaisia valida (Digenea),...

Parasitism by Paratanaisia bragai (Digenea, Eucotylidae) in commom waxbill (Estrilda astrild)

O trematodeo digenético Paratanaisia bragai é descrito como parasito dos túbulos coletores renais e ureteres de aves. Esse helminto é usualmente pouco patogênico para a maioria dos hospedeiros; porém, em altas cargas parasitárias e em animais mais suscetíveis, pode causar sérios danos que result...
