ABSTRACT. Campylobacteriosis (Campylobacter infection) is the most commonly reported foodborne zoonosis in most developed and developing countries. The main source of infection for humans is the handling and / or consumption of undercooked chicken meat. The objective of this study was to typify and evaluate the antimicrobial sensitivity of the Campylobacter strains from samples of chickens (cloacal swab) of intensive production. Four hundred and eighty (480) samples from two farms located in the Department of President Hayes of Paraguay were analyzed. Six lots were sampled from each farm on different days (6 serial samplings). Of the total samples analyzed, 54positive samples were obtained (11,25%), confirmed by microbiological culture and by DNA detection using the polymerase chain reaction (PCR) technique. Campylobacter jejuni (96%) was the most frequently isolated species compared to C. coli (4%). One hundred percent (100%) of the isolated strains were sensitive to erythromycin and tetracycline, on the contrary, 22% of strains resistant to ciprofloxacin were observed.

Keywords : birds; antibiotics; bacteria; Campylobacter; PCR.
