食品动物源大肠杆菌多重耐药性监测

摘要

The present study isolated and identified 294 Escherichia coli strains from food-producing animals, for investigating resistance of E. Coli strains to kinds of antimicrobials. Susceptibility of 294 isolates to 14 antimicrobials was determined by agar dilution method. Results showed that the resistance frequency of different antimicrobials was varied, and multiple resistance was notable. The frequency of tetracycline and sulfamethoxazole/TMP resistance were the highest, both above 80%. Resistance rate of third-generation cephalosporins was lower relatively.%掌握畜禽源大肠杆菌的耐药情况,了解其对各种抗菌药物的敏感程度,自广东地区临床分离鉴定出294株食品动物源大肠杆菌,采用琼脂稀释法测定294株大肠杆菌对14种抗菌药物的敏感性.结果显示,食品动物源大肠杆菌对各抗菌药的敏感性不同,且多重耐药现象较严重；受试大肠杆菌对四环素和复方新诺明的耐药率较高,均达到80％以上；对第3代头孢菌素类耐药率相对较低.
