摘要
通过体外试验和体内试验两种方法研究了黄芩抗鸡大肠杆菌的作用。结果表明,黄芩水煎液对鸡大肠杆菌的最小体外抑菌浓度为2.5 g/mL;当药物浓度为5 g/mL时可使7日龄雏鸡获得90%以上的攻毒保护;药物浓度为10 g/mL时可使100%雏鸡获得攻毒保护,说明黄芩可以对抗鸡大肠杆菌,用于防治鸡的大肠杆菌病。
The effects of Scutellaria baicalensis Georgi on E. coli in vitro and in vivo were studied. The MIC in vitro was 2.5 g/mL determined by bacteriostatic test. Tests in vivo were studied by bacterial infection and drug cure experiments. The drug of 5 g/mL could prevent more than 90% chickens from death and 10 g/mL could prevent 100% chickens from death. Results showed that Scutellaria baicalensis Georgi had antibacterial activity on E. coli and could cure colibacillosis in chickens.
