Abstract: It studied the drug resistance of Yersinia enterocolitica isolated from fish. The tetA,tetC,tetM,sul1,sul2,sul3,aph(3')-Ⅱa,aac(6')-Ⅰb,ant(3'')-Ⅰa and aac(3)-Ⅱa genes were detected using PCR approach. The sensitivities to 14 kinds of antibiotics were evaluated by Kirby-Bauer disc diffusion method. The results showed that the tetA and sul3 genes were not checked out, while the other resistant genes could been seen. The strain was resistant to compound sulfamethoxazole, sulfafurazole, erythromycin, rifampicin, lincomycin and cefaloridine, while it was sensitive to norfloxacin, florfenicol, rocephin and so on. It will benefit the further study of drug-resistant mechanism of Yersinia enterocolitica.

Key words: Yersinia enterocolitica; drug resistance gene; drug resistance phenotype
