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

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.
