Investigation of Salmonella spp. in exotic and native Psittaciformes kept in captivity in the central region of Rio Grande do Sul

ABSTRACT Infectious diseases are known to cause decline in wildlife population and some of them may represent a threat to public health. This study aimed to investigate the occurrence of Salmonella spp. in exotic and native Psittaciformes kept in captivity in the central region of Rio Grande do Sul, Brazil, and to comparing the results obtained through the conventional bacteriological method and the polymerase chain reaction (PCR), using fecal matter collected from the environment, avoiding the containment stress. From August to September 2016, samples of fresh feces were collected from 90 cages in two breeding grounds, representing 180 birds. According to both analysis techniques the samples were negative for Salmonella spp., however, bacteria from the Enterobacteriaceae family: Escherichia coli, Cedecea sp. and Citrobacter freundii were detected. Continuous monitoring of breeding grounds is important since the pathogen investigated can be found in carrier birds and manifest itself in stressful situations presenting risks such as zoonosis and reduced bird health.
