摘要
通过体外和体内两种方法研究黄芩抗鸡大肠杆菌作用。通过体外抑菌作用测定黄芩水煎液对鸡大肠杆菌的最小抑菌浓度(M IC)为2.5g/m l;体内抑菌作用通过对7日龄雏鸡的攻毒与治疗试验来研究,体内治疗药物浓度5g/m l可使90%以上雏鸡获得保护,10g/m l可使100%雏鸡获得保护。以上说明黄芩可以对抗鸡大肠杆菌,可以防治鸡的大肠杆菌病。
To study the effect of Scutellaria baicalensis Georgi on E.coli in vitro and vivo. The MIC was determined by bacteriostatic test in vitro, the MIC value was 2.5g/ml.Bacterial test in vivo was studied by bacterial infection and drug cure experiments, the drug concentration of 5g/ml could prevent 90% chickens from death and 10g/ml concentration could prevent 100% chickens from death. The above results show that Scutellaria baicalensis Georgi has antibacterial activity on E.coli and can cure Cliibacillosis in chickens.
