中文摘要:
      目的:评估" 菌bye-bye" 消毒剂对甲型H1N1 流感病毒PR8(PR8)、呼吸道合胞病毒(RSV)、3 型腺病毒(ADV3)、人感染 H7N9 禽流感病毒(H7N9)的体外杀灭效果。方法:参考《消毒技术规范》和受试产品说明书进行细胞毒性试验、消毒剂中和试验和 对PR8、RSV、ADV3、H7N9 病毒的体外杀灭实验。结果:(1)候选中和剂选定0.02mol/L 硫代硫酸钠(Na2S2O4);(2)候选中和剂、" 菌-bye-bye" 消毒剂及两者混合物对细胞毒性低;(3)候选中和剂能完全中和消毒剂消毒效果;(4)随着" 菌bye-bye" 消毒剂的浓 度增大,病毒杀灭效果亦越好。在其不稀释的条件下,除了PR8 毒株外,其他3 种病毒的平均灭活率均在99.99%以上,且平均病 毒TCID50负对数值(log10 TCID50/mL)均降低4 log10或以上;对半稀释后对RSV 的杀灭效果最好,而对ADV3 的杀灭效果最差。结 论:高浓度" 菌bye-bye" 消毒剂对呼吸道病毒的杀灭效果较好,且对细胞的毒性较小,是一种安全、高效的消毒剂,值得临床推 广。
英文摘要:
      Objective:To evaluate the effect of"Bacteria-bye-bye"disinfectant on killing H1N1 influenza virus PR8 (PR8), respiratory syncytial virus (RSV), adenovirus 3 (ADV3), human H7N9 avian influenza (H7N9) in vitro.Methods:To performed the cytotoxicity test, disinfectant neutralization test and PR8, RSV, ADV3, H7N9 virus killing test in vitro according to the and test product specification.Results:(1)The candidate neutralizing agent was 0.02 mol/L sodium hyposulfite (Na2S2O4); (2)The cytotoxicity of candidate neutralizing agent, "Bacteria -bye-bye"disinfectant and their mixture were low; (3)The candidate neutralizing agent could completely neutralize the effect of disinfectant; (4)The higher concentration of "Bacteria-bye-bye" disinfectant, the better effect on virus killing.In the undiluted condition, except PR8, the virus inactivation rate of other 3 viruses were above 99.99%, and the average viral TCID50 negative logarithm(log10 TCID50/mL) decreased more than 4 log10; After half to half diluted, it had the best killing effect on RSV, but the worst killing effect on ADV3.Conclusion:High concentration "Bacteria-bye-bye" disinfectant is effective on killing respiratory tract viruses, and has less toxic to cells,it is safe and high-performance, which is worthy of clinical promotion.
