摘　　要：[目的]探讨苯扎溴铵消毒液对金黄色葡萄球菌、大肠埃希菌、绿脓杆菌的杀菌效果。[方法]采用工作液直接接种法进行试验观察。[结果]苯扎溴铵对大肠埃希菌、绿脓杆菌基本无杀菌作用,对金黄色葡萄球菌有良好的杀菌效果,且应选择浓度≥0.10%的苯扎溴铵作用10 min以上具有完全杀菌效力。[结论]苯扎溴铵浓度≥0.10%时,适用于对金黄色葡萄球菌消毒。[ Objective] The research aimed to know the germicidal efficacy of benzalkonium bromide disinfectant solution on Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. [ Method] Working fluid direct inoculation method was carried out for experimental observation. [ Result] Benzalkonium bromide had no germicidal effect on Escherichia coli and Pseudomonas aeruginosa, but it had a efficacious effect on Staphylococcus aureus. For Staphylococcus aureus, the concentrations of benzalkonium bromide should be more than 0. 10% and it was used for more than 10 minutes to complete germicidal efficacy. [ Conclusion] Benzalkonium bromide concentrations that was more than 0. 10% could be used for the disinfection of Staphylococcus aureus.
