摘要
目的研究三氯异氰尿酸杀灭龟分枝杆菌的效果及其影响因素。方法采用悬液定量杀菌试验方法进行了实验室观察。结果以含有效氯500 mg/L三氯异氰尿酸溶液作用5 min,对悬液内龟分枝杆菌脓肿亚种杀灭对数值为4.46。随有效氯浓度增加,三氯异氰尿酸对龟分枝杆菌杀灭效果增加;随作用温度的升高,该消毒剂杀菌作用增强;随有机物浓度增加或pH值升高,该消毒剂杀菌作用降低。结论三氯异氰尿酸对龟分枝杆菌脓肿亚种的杀灭效果较好,其杀菌作用受作用温度、有机物和pH值等因素的影响。
Objective To know germicid＇,d efficacy and influencing factor of trichloroisocyanuric acid against Mycobacte- rium chelonae subsp, abscessus. Method Suspension quantitative method was used in the laboratory. Results The kill- ing logarithm value of Mycobacterium chelonae subsp, abscessus exposed to the disinfectant solution containing 500 mg/L a- vailable chlorine [br 5 rain was 4.46. The killing efficacy of the disinfectant increased with the concentration and tempera- ture increasing, and the efficacy decreased with the organic matter and pH increasing. Conclusion The disinfection tablet has good efficacy in killing Mycobacterium chelonae subsp, abscessus. The germicidal efficacy is influenced by tempreture, organic matter and pH value.
