聚维酮碘乳头药浴涂膜剂对奶牛乳房炎致病菌体外抑菌效果评价

摘要

This study aims to understand in vitro bacteriostasis effectiveness(MIC and MBC)of the teat dipping coating agent on major pathogens(Escherichia coli, Staphylococcus aureus, Streptococcus agalactiaeand Streptococcus dysgalactiae)andprovideacertainofscientiifcevidence.Utilizing10timesmicrodilutionmethod, we determine in vitro effectiveness of the teat dipping coating agent on clinical isolates strain of the major cows mastitis. In order to compare bacteriostasis effectiveness of the teat dipping coating agent and antibiotics,we design the control group-ceftiofur and penicillin. The results show that in vitro the agent has signiifcant bacteriostasis effects on four major pathogens of cow mastitis, and the bactericidal and bacteriostatic concentration is lower than ceftiofur and penicillin.%本试验采用10倍稀释法进行了乳头药浴涂膜剂对奶牛乳房炎临床分离菌株（大肠杆菌、金黄色葡萄球菌、无乳链球菌及停乳链球菌）的体外抑菌效果测定。结果显示，乳头药浴涂膜剂对四种致病菌有良好的体外抑菌和杀菌作用，其抑杀菌浓度低于头孢噻呋和青霉素。
