中药制剂对奶牛隐性乳房炎金黄色葡萄球菌和无乳链球菌抑菌试验

摘要

[目的]研究中药制剂对奶牛隐性乳房炎金黄色葡萄球菌和无乳链球菌的抑菌效果。[方法]根据中兽医学理论和中药特性，组成复方中药制剂“增乳健牛散”4种不同的方剂，制备水煎液对奶牛乳房炎的主要病原菌进行抑菌试验。[结果]4种不同的方剂水煎液都有抑菌效果；对金黄色葡萄球菌和无乳链球菌，方剂3为极敏，其他3种不同的方剂为高敏；方剂3抑菌作用最强。[结论]该研究为治疗奶牛隐性乳房炎相关中草药方剂的开发提供了理论依据。%[Objective] This study aimed to analyze the antibacterial activity of herbal preparations against Staphylococcus aureus and Streptococcus agalactiae in cow mastitis. [Method] The crude drug solutions of four different prescriptions for Zen-grujianniusan were prepared through reflux extraction. Their antibacterial activity in vitro against Staphylococcus aureus and Streptococcus agalactiae in cow mastitis were investigated. [Result] Al the four different prescriptions exhibited antibacterial activity against S. aureus and S. agalactiae. Among them, prescription Ⅲ was ex-tremely sensitive, and had the best bactericidal effect. The other three prescriptions were highly sensitive. [Conclusion] This study provides a theoretical basis for the development of herbal preparations for the treatment of cow mastitis.
