First report on the Salmonella enterica and Campylobacter spp. isolation from wild birds Garibaldi (Chrysomus ruficapillus) and Canário-da-terra (Sicalis flaveola)

Abstract

Some species of wild birds have been identified as reservoirs of Campylobacter e Salmonella, they may exert as disseminators of these microorganisms. However, in Brazil, there is no study on the role of wild birds in the transmission of these two pathogens. This study aimed at searching the occurrence of Campylobacter and Salmonella in wild birds that feed in the rice paddies. By using mist nets 23 garibaldis (Chrysomus ruficapillus), one rolinha-picuí (Columbina picui) and one canário-da-terra (Sicalis flaveola) were captured. The birds stool samples were collected using swabs, and they were processed for searching Campylobacter spp. and Salmonella enterica. Eight (32 %) fecal samples collected from C. ruficapillus were Campylobacter-positive and six (24 %) were positive to Salmonella enterica; five (20 %) samples collected from C. ruficapillus and one (4%) from S. flaveola were positive to Salmonella enterica. The two birds C. ruficapillus and S. flaveola showed to be reservoirs of Campylobacter and Salmonella, and they can be potential transmitters of these pathogens. This study is the first report on the isolation of Campylobacter and Salmonella from wild birds C. ruficapillus and S. flaveola.
