20味中药对奶牛隐性乳房炎主要病原菌体外抗菌效果

Antibacterial effect of traditional Chinese medicine on the main pathogenic bacteria of recessive cow mastitis in vitro

采用平板法和试管法,分别测定了20味中草药对奶牛隐性乳房炎临床分离主要病原菌金黄色葡萄球菌和无乳链球菌的抑菌直径、最小抑菌浓度(MIC)和最低杀菌浓度(MBC)。结果发现,20味单味中草药对临床分离的金黄色葡萄球菌和无乳链球菌均有一定的抗菌活性,尤其是蒲公英、黄连、连翘、穿心莲、黄芩、红花、野菊花等7味中草药的体外抗菌效果明显。

The bacteriostasis diameter, MIC and MBC in vitro of the 20 kinds of traditional Chinese medicine was studied with plating test and tube test on Staphytococcus aureus and Streptococcus agalgactiiae which were isolated from recessive cow mastitis. The results showed that S.aureus and S.agalactiae were sensitive to all the 20 kinds of traditional Chinese medicine, and were more sensitive to 7 kinds of traditional Chinese medicine such as Herba Taraxtwi.Rhizoma Coptidis,Fructus Forsythiae.Herba A ndrographitis, Radix Scutellanae, Flos Carthami and Flos Chrysanthemi Indici.
