摘要: 为了解新疆不同地区牛源大肠杆菌对临床常用抗生素的耐药情况,试验从不同地区的5个牛场采集粪样并分离大肠杆菌,采用微量肉汤法检测其对抗生素的耐药情况。结果显示,5个牛场分离的大肠杆菌均对9种抗生素中的氨苄西林有较高的耐药性,最高可达39.3%,且存在多重耐药现象,但仍以0耐为主导。只有拜城县察尔齐镇E牛场分离的大肠杆菌对3种喹诺酮药物耐药,均为6.7%。提示,新疆地区牛源大肠杆菌对常用抗生素耐药情况不严重。

Abstract: This study was aimed to investigate the resistance of Escherichia coli isolates from cattle farms in Xinjiang to antibiotics. The resistances of Escherichia coli isolates from cattle farms in five regions to commonly used antibiotic were determined using microdilution broth assay. Escherichia coli isolates were highly resistant to ampicillin (up to 39.3%) in all regions, and existed multidrug-resistant, but zero resistance was the dominant. Escherichia coli isolates from E cattle farm in Cherqi town, Baicheng county, exhibited resistant to three kinds of quinolones (6.7%). The results suggested that the resistances of Escherichia coli isolates to commonly used antibiotics were not serious in Xinjiang.

Key words: Escherichia coli; antibiotics; resistance; microdilution broth method
