摘要: 目的】研究新疆部分地区牛空肠弯曲菌污染及耐药性。【方法】从乌鲁木齐、昌吉、石河子3个地区共采集牛肛拭子171份。用布氏肉汤初步增菌后,用改良CCD琼脂基础和哥伦比亚血平板2种选择培养基培养,用聚合酶链式反应(PCR)鉴定,最后参照2010年美国临床实验室标准化研究所(CLSI)推荐使用的琼脂扩散法进行药敏试验。【结果】从乌鲁木齐牛场肛拭子分离鉴定到1株空肠弯曲菌(编号为N22),检出率为1.11%(1/90);昌吉牛场肛拭子分离鉴定到1株空肠弯曲菌(编号为C25),检出率为3.33%(1/30)。石河子牛场肛拭子没有分离到空肠弯曲菌。2株空肠弯曲菌对单环β内酰胺类、氨基糖苷类抗生素高度敏感;对喹诺酮类抗菌药物、大环内酯类和大部分头孢菌素类抗生素产生了不同程度的耐药。【结论】新疆牛群存在空肠弯曲菌的感染,感染菌株可用单环β-内酰胺类、氨基糖苷类抗生素进行防治。研究结果可为评价新疆牛群空肠弯曲菌的流行状况和制定防控措施提供科学依据。

Abstract: Objective】 To study the prevalence of campylobacter jejuni from cattle in partial areas of Xinjiang and its drug resistance.【Method】In this experiment, 171 fecal samples were collected from cattle in Urumqi, Changji and Shihezi. After the initial enrichment of Brucella broth, the culture medium was cultured with two improved media, namely, the improved CCD agar base and the Columbia blood plate, and finally identified by polymerase chain reaction (PCR). Finally, the agar diffusion method recommended by the United States Clinical Laboratory Standardization Institute (CLSI) in 2010 was used for drug susceptibility test.【Result】A strain of Campylobacter jejuni (No. N22) was isolated from the Urumqi cattle farm and the detection rate was 1.11%(1/90). A strain of Campylobacter jejuni (No.C25) was identified from Changji cattle farmand the detection rate was 3.33%(1/30).There were no strains of Campylobacter jejuni isolated from Shihezi cattle farm. 2 strains of Campylobacter jejuni were highly sensitive to monocyclic beta lactam and aminoglycoside antibiotics,and showing different degrees ofresistenceto quinolones, macrolides and most of the cephalosporins antibiotics.【Conclusion】The infection of campylobacter jejuni was found from cattle in Xinjiang, and the infection strains could be used to prevent and cure with monobactam and aminoglycoside antibiotics. The results can provide a scientific basis for the evaluation of the prevalence of campylobacter jejuni and the prevention and control measures in Xinjiang cattle herds.
