Abstract: | One hundred and eighty-nine Salmonella isolates from swine were tested for susceptibility to nine antimicrobial agents, presence of dfrAll and class 1 integrons containing dfrA12-orfF-aadA2 cassette. All isolates were multidrug resistant and exhibited highest resistance prevalence to trimethoprim (93%). Most isolates (89%) were mill-positive and 107 isolates (57%) carried dfrAll, all of which were resistant to trimethoprim. Forty-eight dfrA12-harboring strains (45%) were intl1-positive together with dfrA12-aadA2 gene cassette. Fifteen isolates contained dfrA12 but not intl1 and dfrA12-aadA2 cassette. The results indicated a wide distribution of dfrA12 and its role in dissemination of trimethoprim resistance among Salmonella isolates from fattening pigs. |
