First molecular detection of Eimeria spp. in eared doves (Zenaida auriculata) from Brazil

Abstract

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.
