摘　　要：目的了解龟分枝杆菌与结核分枝杆菌标准菌株对含氯消毒剂杀菌的抵抗力。方法采用悬液定量杀菌试验方法进行研究。结果有效氯1000mg/L的消毒液作用2.5min,对龟分枝杆菌脓肿亚种与结核分枝杆菌标准菌株的杀灭对数值均﹥4.00;500mg/L有效氯作用2.5min对龟分枝杆菌脓肿亚种杀灭对数值为3.05,对结核分枝杆菌标准菌株的杀灭对数值为2.10。结论龟分枝杆菌脓肿亚种与结核分枝杆菌标准菌株对含氯消毒剂的抵抗力相近。OBJECTIVE To know resistance capability between Mycobacterium chelonei and Mycobacterium Tuberculosis H37Rv on germicidal efficacy of chlorine disinfectant. METHODS Suspension quantitative germicidal test was carried out. RE- SULTS The killing logarithm value of Mycobacterium chelonei and Mycobacterium Tuberculosis H37Rv exposed to the disinfec- tion solution containing 1 000 mg/L available chlorine for 2.5 min were 〉 4.00. The killing logarithm value of Mycobacterium ch- elonei exposed to the solution containing 500 mg/L available chlorine for 2.5 rain was 3.05 and for Mycobacterium Tuberculosis H37Rv was 2.10. CONCLUSION The resistance capability with Mycobacterium chelonei and Mycobacterium Tuberculosis H37Rv on germicidal efficacy of chlorine disinfectant are similar.
