This study aimed to identify molecular markers associated with antimicrobial resistance and genotype isolates of Campylobacter spp. from broiler and swine flocks due to its importance to one-health. C. jejuni (n=27) and C. coli (n = 35) strains were screened for the antimicrobial genetic markers C257T in gyrA, A2074C and A2075G in 23S rRNA, CmeABC, ermB, tetO and blaOXA61 by PCR. Fifteen strains had SVR-flaA and porA genes sequenced to evaluate their genetic diversity. Among C. jejuni strains 62.96% had C257T mutation and only one strain had A2075G mutation. CmeA, cmeB, cmeC, tetO and blaOXA61 were detected respectively in 92.59%, 100%, 100%, 85.19%, 85.19% of the strains. All C. coli had C257T mutation; 48.75% had A2075G and cmeA, cmeB, cmeC, tetO, blaOXA61 were detected in 8.57%, 94.29%, 91.43%, 91.43%, 80%, respectively. Twelve porA and SVR-flaA alleles were detected, with a Simpson index of diversity value of 0.962.
