摘要
本试验旨在调查新疆石河子地区奶牛乳房炎源大肠杆菌的某些生物学特性及其耐药状况,以提高药物疗效,减少牛奶中药物的残留。试验从新疆石河子地区患乳房炎奶牛的乳样中分离纯化并鉴定出21株大肠杆菌,并对大肠杆菌分离株进行抗菌药物敏感性分析。结果表明,21株大肠杆菌对21种抗菌药物中的6种药物耐药率超过50%,其中最多的耐药15种,最少的耐药5种,耐药6及6种以上的菌株共占到76.19%。提示,该地区奶牛乳房炎源大肠杆菌对多种药物已产生了不同程度的耐药性,且存在严重的多重耐药情况。
The aim of the study was to investigate the biological characteristics and antibiotic resistance of E.coli isolated from bovine mastitis in Shihezi area in Xinjiang so as to raise therapeutic effect and decrease drug residue.The milk samples of bovine mastitis were collected from Shihezi and a total of 21 E.coli isolates were further identified by microbiological tested，and antibiotic resistance of 21 strains were also studied.The results showed that among the 21 strains，the resistant rates of 6 out of 21 antibacterial drugs exceeded 50%，the E.coli could resist 15 kinds of antibacterial drugs at most and 5 kinds of antibacterial drugs at least，and the E.coli strains which were resistant 6 or more antibacterial drugs occupied 76.19%.So we concluded that E.coli isolates had produced different level resistance to many kinds of antibacterial drugs and presented serious multiple antibiotic resistance.
