中草药对奶牛乳房炎病原菌的体外抑菌作用

In vitro Bacteriostasis of Chinese Herbal Medicine against Mastitis Pathogens in Dairy Cows

[目的]寻找治疗奶牛乳房炎的新途径。[方法]选择常用7味中草药煎剂及5种复方制剂,采用试管二倍稀释法,对从患隐性乳房炎奶牛的乳汁中所分离的5种致病菌进行抑菌试验,并测定最小抑菌浓度(MIC)和最小杀菌浓度(MBC)。[结果]结果表明:野菊花、黄连、大青叶、复方Ⅰ及复方Ⅴ对这5种病原菌均具有较强的体外抗菌活性。[结论]该研究为研制防治奶牛乳腺炎中草药制剂的科学组方提供了理论依据。

The objective of this study was to explore new means of dairy cow mastitis treatment.The study used 7 decoction of Chinese herbal medicine and 5 kinds of compound preparations,used test tube 2-fold dilution method to conduct inhibitory test on 5 pathogens and determined the minimal inhibitory concentration（MIC） and minimum bactericidal concentration（MBC）.The result showed that Chrysanthemum indicum,Rhizoma coptidis,Folium isatidis,Compound preparation I and Compound preparation V had fairly strong in vitro bacteriostasis activities against 5 pathogens.The study provided theoretic background for the study on the control of dairy cow mastitis by applying the scientific prescription of Chinese herbal preparations.
