目的了解五种常用消毒剂对临床分离的鲍曼不动杆菌的杀灭效果,为实际使用提供参考依据。方法采用悬液定量杀菌试验进行了实验观察,并与消毒试验指标菌大肠杆菌标准株作平行比较。结果用含有效氯400mg/L的含氯消毒液作用3 min、200 mg/L苯扎溴铵消毒液作用5 min、2500 mg/L有效碘的聚维酮碘消毒液和三氯生乙醇消毒液作用1 min以及含体积分数50%的乙醇溶液作用1 min,对临床分离的鲍曼不动杆菌和大肠杆菌标准菌株的平均杀灭率均能达到100%。临床分离的鲍曼不动杆菌与大肠杆菌标准株对上述五种消毒剂抗力没有明显差异。结论在常规使用浓度时,五种常用消毒剂对鲍曼不动杆菌临床分离株都具有良好的杀灭效果。
Objective To understand the killing effect of five commonly used disinfectants on Acinetobacter baumannii clinically, and provide a reference for practical use. Methods Suspension quantitative germicidal test was carried out experimentally and compared with the standard strain of E. coli which was the indicator of disinfection test. Results The effects of disinfecting with povidone-iodine containing 2500mg / L of effective povidone-iodine and disinfecting with triclosan Liquid for 1 min and ethanol solution containing 50% volume fraction for 1 min, the average killing rate of clinically isolated strains of Acinetobacter baumannii and Escherichia coli was 100%. Clinical isolates of Acinetobacter baumannii and Escherichia coli standard strains of the above five disinfectant resistance no significant difference. Conclusion The five commonly used disinfectants have a good killing effect on the clinical isolates of Acinetobacter baumannii at conventional concentrations.
