The thermophilic bacteria of Campylobacter spp. It Constitutes pathogens frequently identified in cases of diarrhea in humans. A locally non-existent evidence of published works of Campylobacter spp. In laying hens. The objective of this investigation was to determine the presence of Campylobacter spp. And resistance profile of strains isolated from laying hens, located in the poultry division of the Faculty of Veterinary Sciences of the National University of Asunción. A total of 150 cloacal swab specimens were collected from laying hens of the Hisex Brown line. The samples were submitted to microbiological analysis and species identification based on morphological and biochemical characteristics. The antimicrobial resistance to Ciprofloxacin and Erythromycin, was performed using antibiotic gradient strips method by agar diffusion. Of the 22 samples were positive to Campylobacter spp, jejuni species, representing a presence of 15%. Results of antimicrobial resistance demonstrated that strains of Campylobacter jejuni showed 95% resistance to Ciprofloxacin. No resistance to Erythromycin was observed. A low prevalence of Campylobacter spp. In laying hens However, the high resistance observed to Ciprofloxacin should serve as a basis for the correct antimicrobial activity in the poultry production chain.
