摘要: 湖北省某猪场新生仔猪发生以剧烈腹泻、排出黄色粪便并迅速脱水死亡为主要症状的疾病,对送检病料,通过细菌培养、革兰氏染色、PCR等方法进行鉴定,确定新生仔猪病是由产肠毒素大肠杆菌感染引起。药敏试验结果表明,该分离菌株对喹诺酮类、氨基糖苷类、头孢类等药物敏感;对青霉素类、四环素类、氯霉素类、磺胺类等药物耐药,主要是阿莫西林、氨苄西林、氟苯尼考、四环素、多西环素、磺胺异恶唑等。

Abstract: Newborn piglets on a pig farm in Hubei province developed a disease with severe diarrhea, discharge of yellow feces and rapid dehydration death as the main symptoms. The disease materials submitted for inspection were identified through bacterial culture, gram staining, PCR and other methods to determine the newborn piglets. The disease is caused by infection with enterotoxigenic Escherichia coli. The results of the drug sensitivity test showed that the isolated strain was sensitive to quinolones, aminoglycosides, cephalosporins and other drugs; it was resistant to penicillins, tetracyclines,chloramphenicol,sulfonamides and ampicillin, florfenicol, tetracycline, doxycycline, sulfisoxazole, etc.

Key words: Escherichia coli, isolation and identification, drug allergy testing
