目的观察4种市售含碘消毒剂的杀菌效果,以了解含碘消毒剂产品质量状况。方法用悬液定量杀菌试验法,对随机抽检的4种不同含碘消毒剂产品进行实验室检测。结果以有效碘300 mg/L和1 000 mg/L络合碘作用10 min,分别对大肠杆菌、金黄色葡萄球菌和白色念珠菌平均杀灭率仅达到99.9%以上。有效碘100 mg/L碘伏消毒液对试验菌可达到完全杀灭。复强黏膜碘原液作用5 min以上可有效杀灭试验菌。非溶出性高聚碘原液作用至9 min对试验菌杀灭对数值仅2.22。结论市售不同种类及品牌含碘消毒剂的消毒效果存在较大的差别。
Objective To observe the bactericidal effect of four commercially available iodine-containing disinfectants to understand the quality of iodine-containing disinfectants. Methods Suspension quantitative germicidal test method, random sampling of four different iodine disinfectant products for laboratory testing. Results The effective killing rates of Escherichia coli, Staphylococcus aureus and Candida albicans were only 99.9% when iodine was 300 mg / L and 1000 mg / L respectively. Effective iodine 100 mg / L iodophor disinfectant to test bacteria can be completely killed. Resuscitation mucosal iodine solution for 5 min or more can effectively kill the test bacteria. Non-leaching high iodine solution to 9 min on the experimental bacteria kill logarithm of only 2.22. Conclusion There are big differences in the disinfection effects of different types and brands of iodine-containing disinfectants on the market.
