| 摘 要： | ［目的］调查安徽省某种鸡场发生的以心包炎、肝周炎及腹膜炎为主要症状的疾病的病原，为临床用药提供依据。［方法］采集病料，对病原菌进行分离培养，通过形态学观察、生理生化试验和16S rRNA序列分析对病原菌鉴定，并做药敏试验，根据药敏试验结果进行临床用药治疗。［结果］分离培养得到的病原菌其形态、生理生化特性、16S rRNA序列均与大肠杆菌相符。药敏试验结果显示，该致病菌对菌必治、阿米卡星、壮观霉素等高度敏感；对头孢拉定表现为中度敏感；对呋喃妥因、庆大霉素表现低度敏感。采用菌必治进行治疗，3 d后病情得到控制。［结论］对病原菌分离、鉴定及药敏试验是临床上治疗控制鸡大肠杆菌病的有效途径。
