抗鸡致病性大肠杆菌中药的筛选及其疗效观察

[目的]为获得有效防治鸡大肠杆菌病的中药制剂奠定基础。[方法]以西药盐酸洛美沙星氯化钠注射液为对照,对15味中药及7个自拟中药复方进行药敏试验,并对7个中药复方和体外抑菌效果较好的单味中药进行体内试验。[结果]药敏试验结果表明,15味单味中药均有一定的抗大肠杆菌作用,其中以芦荟、石榴皮、地榆等抑菌效果明显。7个自拟复方中复方一、复方二和复方五的抗大肠杆菌效果较好。体内试验结果表明,中药对人工感染大肠杆菌的鸡只治疗效果优于西药,以复方一和复方二效果较好。[结论]中药制剂对鸡大肠杆菌病具有较好的治疗效果,但其在体内与体外的抑菌作用机制有所不同。     

抗鸡致病性大肠杆菌中药的筛选及其疗效观察(英文)

[Objective] The aim of this study was to lay a foundation for obtaining effective traditional Chinese medicine preparations controlling chicken colibacillosis. [Method] With the western medicine Lomefloxacin Hydrochloride and Sodium Chloride Injection as the control, drug sensitivity tests of 15 single traditional Chinese herbs and seven self-made Chinese herbal compounds were conducted. Subsequently, the single traditional Chinese herbs presenting good in vitro antibacterial effects against Escherichia coli and all the seven compounds were given to the chicks artificially infected with E.coli to observe their efficacies. [Result] The results of drug sensitivity tests showed that all the 15 traditional Chinese herbs had certain antibacterial effect against E.coli, among which aloe, pomegranate rind and radix sanguisorbae were the best. Compound 1, 2 and 5 had good antibacterial effects in vitro. By in vivo test, traditional Chinese medicines showed superior efficacies on infected chicks than western medicine, and compound 1 and 2 performed well. [Conclusion] Traditional Chinese medicine preparations are good at controlling Chicken colibacillosis, but their bacteriostasis mechanism in vivo was different with that in vitro.
