摘　　要：为研究有机物、温度和pH对氯甲酚纳米乳消毒剂杀菌效果的影响,本文以大肠杆菌为试验菌,利用悬液定量杀灭试验方法进行试验。结果表明:0%、25%和50%小牛血清对氯甲酚纳米乳消毒剂杀菌作用均无影响;该消毒剂的杀菌效果随时间延长而增强,且在(10±1)℃和(20±1)℃的条件下均有重度影响,(30±1)℃无影响;在pH 4.64、6.67和8.68的条件下均无影响。结论如下:有机物和pH对氯甲酚纳米乳消毒剂杀灭大肠杆菌的效果均无影响,但在不同温度条件下影响不同,临床实践应用时需注意。Organic matter,temperature and pH were studied on bactericidal efficacy of chlorocresol nanoemulsion disinfectant.Suspension quantitative killing test method was used with E.coli as test bacteria.The results showed that0%,25%and 50%calf serum had no effect on the bactericidal efficacy of chlorocresol nanoemulsion disinfec⁃tant.The bactericidal efficacy of the disinfectant increased with the prolongation of action time,both(10±1)℃and(20±1)℃had serious effects,but(30±1)℃had no effect.pH 4.64,6.67 and 8.68 had all no effect.These results in⁃dicated that organic matter and pH had no effect on the bactericidal action of chlorocresol nanoemulsion disinfectant against E.coli.However,different temperatures had different effects,so attention should be paid to in clinical appli⁃cation.
