Abstract

GOMES, Fabiane R. et al. Campylobacter jejuni occurrence in chicken fecal samples from small properties in Pelotas, southern of Brazil. Braz. J. Microbiol. [online]. 2006, vol.37, n.3, pp.375-378. ISSN 1517-8382.  http://dx.doi.org/10.1590/S1517-83822006000300032.

The aim of this study was to evaluate the occurrence of thermophilic Campylobacter species in broiler flocks from 26 small properties located near the campus of Federal University of Pelotas, RS, Brazil. A total of 404 chicken fecal samples were analyzed and after isolation, identification and biotyping was performed according to Lior´s scheme. Twenty one strains (5.2%) of Campylobacter jejuni biotype II were isolated from animals from seven properties (26.9%), with a variation from 3% to 34.6% among the positive properties. We also analyzed twelve C. jejuni isolates by polymerase chain reaction (PCR), using specific primers that generate a fragment of 402 pb. Our study allowed us to observe that chickens raised in non-industrial establishments without sanitary attention can harbour C. jejuni in their intestinal tract, and by doing so, they could be a serious health risk to humans.

Keywords : Campylobacter jejuni; thermotolerant species; diarrhea; chicken.
