摘　　要：为了研究复合酚、氢氧化钠、聚维酮碘等消毒剂在不同浓度、不同作用时间对牛型结核分枝杆菌的杀菌效果;本研究以浓度为20%、10%、5%、2%、1%、0.5%、0.2%、0.1%、0.01%的消毒剂分别对牛型结核杆菌进行处理,作用时间分别为10、20、30、60 min、1、2、6、12 h;结果显示,浓度在0.2%及以上的复合酚在12 h内可杀灭牛型结核分枝杆菌,1%以上聚维酮碘处理6 h以上可杀灭牛型结核分枝杆菌,而所有试验浓度的氢氧化钠对牛型结核分枝杆菌没有杀灭作用;本研究结果表明,复合酚和聚维酮碘可用于环境的牛型结核分枝杆菌的净化。In this study,we investigated the germicidal efficacy of compound phenol,sodium hydroxide and povidone-iodine on Mycobacterium bovis under various concentration and incubation time.The isolates cultures were incubated with different concentration of the disinfectant（with the concentrations 20%,10%,5%,2%,1%,0.5%,0.2%,0.1%and 0.01%respectively）.The incubation time were 10,20,30,60 min,l,2,6 h and 12 h respectively.The results showed that 0.2%Compound phenolic and above sterilized the Mycobacterium bovis with 12 h incubation.1%povidone-iodine and above sterilized the Mycobacterium bovis with incubation time at least 6 h.However even 20%sodium hydroxide had no role in killing Mycobacterium bovis with 12 h.The results showed that compound phenolic and povidone-iodine could be used as disinfectant to purify the environment for Mycobacterium bovis.
