SILVA, D.T. et al. Occurrence of Campylobacter in poultry, meat chicken and human feces, and cdt GENES research. Arq. Bras. Med. Vet. Zootec. [online]. 2014, vol.66, n.1, pp.297-304. ISSN 0102-0935.

A hundred chicken fecal samples, a hundred samples of retail poultry products and a hundred samples of human feces were collected and tested for the presence of Campylobacter. The species identification and the analysis for the presence of cdt genes, responsible for encoding the cytolethal distending toxin, were performed by PCR. Campylobacter was found in 61% of the chicken fecal samples, in 20% of the poultry products and in 3% of the human feces. Most isolates were identified as C. jejuni. In 93.5% of these isolates, the cdt genes have been detected. Despite the occurrence of Campylobacter in feces of humans has been low, the prevalence in broilers and poultry products was high, which, combined with the presence of cdt genes in most isolates, represents a potential risk to consumers. These results suggest there is a need for preventive measures in the production system and good manufacturing practices in the industry so as to minimize contamination of products and reduce the risk to consumers.

Keywords : chicken feces; Campylobacter; cdt genes; human feces; poultry products.
