Prevalence, Tetracycline Resistance and Tet(O) Gene Identification in Pathogenic Campylobacter Strains Isolated from Chickens in Retail Markets of Lima, Peru.

ABSTRACT: Background: In this study, we aimed to estimate the prevalence, tetracycline resistance and presence of Tet(O) in Campylobacter strains isolated from chicken in markets of Lima, Peru. Methods: A total of 250 chicken samples were obtained from traditional markets (skin, n = 120) and supermarkets (meat, n = 130). Samples were subjected to microbiological assays for identification of Campylobacter spp. according to ISO 10272-2017, and the isolates were then submitted to species identification by PCR. Phenotypic resistance to tetracyclines was assessed by the Kirby−Bauer test, and the presence of the Tet(O) gene was determined by PCR. Results: A significantly higher prevalence (p < 0.0001) of Campylobacter coli in skin samples from traditional markets (97.5%) than in meat samples from supermar
