摘　　要：采用悬液定量杀菌试验，比较了消毒剂鉴定试验中规定采用的不同细菌繁殖体对有效氯的抗力．结果，革兰阳性菌对消毒剂二氯异氰尿酸钠溶液中有效氯的抗力比革兰阴性菌强；金黄色葡萄球菌（ＡＴＣＣ ６５３８）与海氏肠球菌（ ＡＴＣＣ １０５４１）的抗力相近；大肠杆菌 ８０９９株的抗力，较该菌 ＡＴＣＣ１０５３６株强，与绿脓杆菌（ＡＴＣＣ １５４４２）较接近。对该消毒剂含有效氯２５ ｍｇ／Ｌ溶液抗力的大小，依次为海氏肠球菌、大肠杆菌（８０９９）、金黄色葡萄球菌、绿脓杆菌、大肠杆茵（ＡＴＣＣ １０５３６），说明同一种菌的不同菌株抗力差距较大。Using suspension quantitative bactericidal test, the resistance of vegetative forms of various bacteria specified to be used in disinfectant verification test was compared. The results showed that the resistance of gram--positive bacteria to available chlorine in the disinfectant sodium dichloroisocyanurate solution was higher than that of gram-negative bacteria, the resistance of Staphylococcus aureus (ATCC 6538) approximated that of Enterococcus hirae (ATCC 10541) and the resistance of Escherichia coli strain 8099 was higher than that of ATCC strain 10536 of this bacteria and approximated that of Pseudomonas aeruginosa (ATCC 15442). The resistance of the bacteria to the disinfectant solution containing available chlorine 25 mg / L in decreasing order was Enterococcus hirae, E. coli (8099), Staphylococcus aureus, Pseudomonas aeruginosa and E. coli (ATCC 10536), indicating that the resistance of different strains of same species of bacterium differs greatly.
