目的:针对3种实验室常规消毒方法对流感病毒灭活效果进行评价。方法:采用紫外照射物理方法及乙醇和84消毒液2种化学方法，分别对流感病毒进行消杀，不同时间或浓度的消毒方法处理病毒样本后感染MDCK细胞，观察细胞病变效应(cytopathic effect, CPE)鉴定对流感病毒灭活效果。结果:紫外照射流感病毒时间≥1 min、或75%乙醇处理流感病毒0.25～32 min、或84消毒液有效氯浓度≥400 mg/L且室温消杀流感病毒时间≥1 min，上述3种条件下均检测不到病毒感染性。结论:摸索了实验室常规消毒方法灭活流感病毒的条件，为建立流感病毒实验室防护规范和应急处置技术方案提供了参考数据。“,”Objective:To evaluate the effectiveness of three laboratory routine disinfection methods on influenza virus inactivation.Methods:The physical method of ultraviolet irradiation and two chemical methods of ethanol and “84 disinfectant” were used to inactivate the influenza virus respectively. After disinfecting the virus samples at different times or concentrations, MDCK cells were inoculated and the inactivation effect of influenza virus was identified by observing cytopathic effect (CPE).Results:When the influenza virus was irradiated by ultraviolet light for ≥1 min, treated with 75% ethanol for 0.25-32 min, the effective chlorine concentration of “84 disinfectant” was ≥400 mg/L, and the influenza virus was disinfected at room temperature for ≥1 min, no virus infectivity could be detected under the three conditions.Conclusions:The condition of inactivating influenza virus by routine disinfection methods in laboratory was explored, which provided reference data for establishing the protection specifications and the emergency treatment plans for influenza virus laboratories.
