摘要: 近年食源致病菌耐药性较严重,为了解四川省动物性食品源沙门氏菌(Salmonella spp.)耐药情况,本试验采用肉汤微量稀释法,对源自四川省动物性食品的76株沙门氏菌进行了25种抗生素(组合)的敏感性试验。结果表明76株沙门氏菌对利福平(96.05%)、黏菌素(78.95%)、磺胺异噁唑(64.47%)、先锋唑啉(60.53%)、氨苄西林(60.53%)、阿莫西林—克拉维酸(56.58%)、甲氧苄啶(53.95%)及强力霉素(52.63%)耐药率较高。76株沙门氏菌对25种抗生素(组合)共产生了66种耐药谱,多重耐药率达97.37%(74/76),主要对青霉素类、先锋唑啉、链霉素、四环素类、磺胺类药物及黏菌素表现出多重耐药。结果表明,四川地区食源沙门氏菌耐药性已较为严重,应加强连续监测。

Abstract: Recently the drug resistance of pathogens in food has arisen attention. To analyze the drug resistance of Salmonella spp. in animal food in Sichuan,76 strains isolated from animal food in Sichuan were tested against 25 antibiotics using broth micro-dilution method. Among 76 Salmonella strains,96.05%,78.95%,64.47%,60.53%,60.53%,56.58%,53.95% and 52.63% were resistant to Rifampin, Polymyxin E, Sulfisoxazole, Cephazolin, Ampicillin, Amoxicillin-Clavulanic, Trimethoprim and Doxycycline, respectively, and displayed different resistance rates to the rest drugs. There was a total of 66 kinds of resistance spectrum and the rate of multi-drug resistance was 97.37%(74/76). The whole strains demonstrated multi-drug resistance mainly to Penicillins, Cephazolin, Streptomycin,Tetracyclines, Sulphonamides and Polymyxin E. The drug resistance of Salmonella spp. from foods of animal origin in Sichuan was comparatively serious,so we must monitor it continuously and pay more attention to it.
