RESUMEN

Coccidiosis is a disease that limits the production and marketing of gallinaceous birds in North America, especially quails, pheasants and chukar partridges. Virtually no research has been conducted in South America on the causative agents of diseases among these birds, including coccidia. The aim of this work was to make first observations on Eimeria spp. in the chukar partridge Alectoris chukar and the grey quail Coturnix coturnix, which are reared for meat in Brazil. Fecal and tissue samples were collected from commercial farms and were examined for oocysts, gross and microscopic lesions or endogenous stages. From this examination, it was found that partridges raised in Brazil did not have any visible infection. However, grey quails presented mild infection and two Eimeria species that had previously been described in other birds were identified.

A coccidiose é uma enfermidade limitante para a produção e comercialização de aves de corte na América do Norte, principalmente codornas, faisões e a perdiz de chukar. Praticamente nenhuma pesquisa foi realizada na América do Sul sobre os agentes causadores de doenças nessas aves, incluindo coccídios. O objetivo deste trabalho foi realizar as primeiras observações sobre Eimeria spp. em perdiz de chukar Alectoris chukar e codornas cinzentas Coturnix coturnix criadas para abate no Brasil. Amostras de fezes e de tecidos foram coletadas em granjas comerciais e examinadas para oocistos, lesões macroscópicas e microscópicas ou estágios endógenos. Após o exame, verificou-se que a criação de perdizes, no Brasil, não tinha infecção visível. No entanto, as codornas cinzentas apresentaram uma infecção leve e foram identificadas duas espécies de Eimeria descritas anteriormente em outras aves.(AU)
