Plasmid DNA profiles analysis offer scientific reference to molecular epidemiology investigation of avian colibacillosis.

质粒DNA图谱分析为从分子水平上进行鸡大肠杆菌病流行病学调查提供了基础材料。

The research aimed to provide new thoughts and basis for the clinical control of colibacillosis in broilers, Chinese herbal compound prescription was selfmade according to Chinese veterinary theory.

［目的］为肉仔鸡大肠杆菌病的临床防治提供新思路和依据。

Controlling colibacillosis in broilers with Chinese herbal medicine had an important significance for solving the drug-resistance and residue problems of antibiotic.

结论］利用中草药防治肉仔鸡大肠杆菌病对解决抗生素的耐药性和药物残留问题有重要意义。

The curative effect of this compound Chinese herbal medicine on the control of chicken colibacillosis was studied by bacteriostatic test in vitro,artificial infection and treatment test and natural infection and treatment test.

方法根据中兽医的基本理论筛选组建中草药方剂，并通过体外抑菌、人工感染治疗和自然感染治疗试验研究该复方中草药防治鸡大肠杆菌病的疗效。

Artificial infection and treatment test showed that this Chinese herbal medicine had better curative effects on chicken colibacillosis and the mortality rate of chicken in the groups with middle and high dosage were lower than that in the group with ciprofloxacin lactate and obviously lower than that in pathogenetic control group.

人工感染治疗试验表明该中草药方剂对鸡大肠杆菌病有较好的治疗效果，而中、高剂量组的鸡只死亡率均低于乳酸环丙沙星组，且明显低于发病对照组。
