A zoonosis and bacterial disease, campylobacteriosis is responsible for frequent cases of human gastroenteritis worldwide. Campylobacter spp. presents the virulence factor called cytolethal distensive toxine (CDT), responsible for diarrhea and codified by the cdt gene. The aims of this study were: 1) to isolate and identify Campylobacter spp. strains from 102 carcass swabs and 102 rectal swabs of sheep (Ovis aries) and seven samples of wastewater, before and after the disinfection treatment, collected from the abattoir of the state of São Paulo; and 2) to detect the presence of cdt gene complex by Multiplex-PCR in strains of Campylobacter spp. Seven strains of Campylobacter coli were isolated and identified by phenotypic and genotypic methods: 4/102 (3.92%) from rectal swabs, 1/102 (0.98%) from carcass swabs and 2/7 (28.5%) from wastewater. From the rectal swab samples 2/7 (28.6%) strains were detected with the cdt gene. This is the first report on the isolation of Campylobacter coli from sheep abattoir, and of strains carrying the cdt gene complex in this animal species in Brazil.
