青海省部分地区犬与牦牛小肠结肠炎耶尔森菌的分布及药敏试验

Distribution and Drug Sensitivity Test of Yersinia enterocolitica Between Dogs and Yaks in Partial Areas of Qinghai Province

应用常规细菌分离培养鉴定技术对青海省部分地区犬与牦牛粪便中小肠结肠炎耶尔森菌带菌率进行检测并进行检出菌的药敏试验。结果显示,在177份样品中共检出16株小肠结肠耶尔森菌,检出率为9.04%(16/177),其中牦牛粪便中小肠结肠耶尔森菌检出率为14.04%(8/57),宠物犬粪便中的检出率为5.88%(6/102),藏獒粪便中的检出率为11.11%(2/18)。药敏试验结果显示,16株分离菌对40种药敏纸片的平均耐药率为47.19%。致病性试验表明随机选取的5株不同动物源的野生菌株对小鼠具有致死效应。

Pathogenic Yersinia enterocolitica were isolated in feces of dogs and yaks in Qinghai province,and drug sensitivity tests were conducted.The results showed that out of 177 samples,16 Yersinia enterocolitica strains were detected with a positive rate of 9.04%（16/177）.The detection rates of Yersinia enterocoliticain the feces of Yaks,dogsand Tibetan Mastiffs′were 14.04%（8/57）,5.88%（6/102）and 11.11%（2/18）,respectively.The results of drug sensitivity tests showed that the average drug resistance rate of 16 Yersinia enterocolitica strains was 47.19% for the 40 types of drugs tested.Whereas,5 strains of different wild animal sources randomly selected had lethal effects to mice in pathogenic tests.
