摘要: 为了解来苏儿、百毒杀、84消毒液对金黄色葡萄球菌的抑制作用,本试验通过采集脓汁并分离鉴定出金黄色葡萄球菌,采用抑菌试验和悬液定量杀灭试验对来苏儿、百毒杀、84消毒液杀灭金黄色葡萄球菌的效果进行观察。结果显示:84消毒液和百毒杀作用于金黄色葡萄球菌的抑菌圈直径明显大于来苏儿,且5~20 min内能快速高效杀灭金黄色葡萄球菌,来苏儿的杀灭率较低。来苏儿对金黄色葡萄球菌的抑制作用较弱,百毒杀和84消毒液对金黄色葡萄球菌有很好的杀灭作用,84消毒液优于百毒杀。

Abstract: To study the effects of Lysol, didecyl dimethyl ammonium bromide solution and 84 disinfectant in killing Staphylococcus aureus. Bacteriostatic test and suspension quantitative killing test were conducted in the laboratory, respectively. Larger inhibition zone were observed onagar media which were treated with 84 disinfectant and didecyl dimethyl ammonium bromide solution, and Staphylococcus aureus could be killed by them quickly and effectively in 5~20 min. It is suggested that the sterile efficacy of Lysol is weaker significantly than other two disinfectants on Staphylococcus aureus. Among of these disinfectants, 84 disinfectant is the best choice in killing pathogenic bacteria clinically.
