摘要
【目的】调查新疆焉耆县不同动物粪源大肠杆菌对临床常用抗菌药物的耐药情况。【方法】从该县主要的规模化养殖场分别采集仔猪(日龄分别为40和60 d)、妊娠母猪、牛及羊的粪便。采用琼脂稀释法,对分离出的大肠杆菌进行最小抑菌浓度测定。【结果】猪粪源大肠杆菌对被检抗菌药物耐药严重程度依次为40日龄仔猪>60日龄仔猪>妊娠母猪粪源大肠杆菌;牛源大肠杆菌(除阿米卡星)和羊源大肠杆菌(除安普霉素)对其他被检抗菌药物均有不同程度的耐药。仔猪粪源大肠杆菌以6~8耐为主(40日龄:89.2%,74/83;60日龄:49.0%,49/100),妊娠母猪粪源大肠杆菌以2~4耐为主(63.3%,62/98),牛粪源大肠杆菌以1~2耐为主(58.0%,47/81),羊粪源大肠杆菌以0~2耐为主(80.2%,138/172)。【结论】新疆焉耆县主要的规模化养殖场不同动物粪源大肠杆菌对临床常用抗菌药物的耐药程度不同,但在养殖过程中应考虑耐药情况需合理使用抗菌药物。
【Objective】To investigate the resistance of Escherichia coli from different animals to commonly used antimicrobial agents in Yanqi County,Xinjiang.【Method】Feces of piglets(aged40days and60days)were collected from the main farms in the county,and the feces of pregnant sows,cattle and sheep were collected,respectively.The minimum inhibitory concentration of Escherichia coli was determined by agar dilution method.【Result】The results showed that the resistance severity of fecal Escherichia coli from40-day-old>fecal Escherichia coli from60-day-old piglets>fecal Escherichia coli from pregnant sows.Escherichia coli from sheep and cattle had different degrees of resistance to detected antimicrobials.Escherichia coli from piglets was mainly resistant to6-8(40days old:89.2%,74/83;60days old:49.0%,49/100),and pregnant sows was mainly resistant to2-4(63.3%,62/98).Escherichia coli from cattle was mainly resistant to1-2(58.0%,47/81)and sheep was mainly resistant to0-2(80.2%,138/172).【Conclusion】Escherichia coli from different animals in the main farms had different degrees of resistance to the commonly used antibiotics in clinics in Yanqi County,Xinjiang,so in the breeding process,the rational use of antimicrobial agents should be taken into consideration in the case of bacterial resistance.
