Observation on Germicidal Efficacy of an Iodophor Disinfectant

目的了解某碘伏消毒液杀菌效果及相关性能,为正确、合理、有效地使用消毒剂提供科学依据。方法采用悬液定量杀菌试验方法进行了实验室检测。结果以含50mg/L有效碘的碘伏消毒液对金黄色葡萄球菌和大肠杆菌作用3min,杀灭对数值>5.00,对白色念珠菌作用5min,杀灭对数值>5.00;碘伏消毒液在37℃存放3个月,有效碘含量下降率为7.84%。结论某碘伏消毒液对细菌繁殖体和真菌都具有很强的杀灭效果,稳定性良好。

Objective To observe the germicidal efficacy and related properties of an iodopher disinfection solution, and to provide a scientific basis for using the iodine disinfectant correctly, reasonably and effectively. Methods The suspension quantitative disinfection tests were conducted in laboratory. Results Staphylococcus aureus and Escherichia coli could be killed by iodine disinfectant of 50 mg/L available iodine for 3 min, the killing log value was above 5.00. Candida albicans was tested for 5 min, and the killing log value was above 5.00. After the iodophor disinfection solution was stored at 37℃ for 3 months, its available iodine content decreased by 7.84%. Conclusions Iodophor disinfection solution has high efficacy in killing vegetative forms of bacteria and fungi. And the stability is good.
