为对防制感染性腹泻的消毒工作提供依据,用悬液定性杀菌试验,测定了稳定性二氧化氯、过氧戊二酸、氯己定对从临床分离的肠出血性大肠杆菌O157:H7和3株气单胞菌作用1min和10min的最小杀菌浓度。结果,二氧化氯作用1min和10min杀灭所试菌的最低浓度分别为≥920mg/L和≥701mg/L;过氧戊二酸者分别为≥5500mg/L和≥5170mg/L; 氯己定者分别为≥9000mg/L和≥792mg/L。说明所试3种消毒剂对4株临床分离到的肠道致泻菌均有良好杀灭作用。
In order to provide basis for the prevention and control of infectious diarrhea disinfection, qualitative suspension test was used to determine the stability of chlorine dioxide, perylene glutaric acid, chlorhexidine from clinical isolates of enterohemorrhagic Escherichia coli O157: H7 And 3 Aeromonas effect 1min and 10min minimum bactericidal concentration. The results showed that the minimum concentrations of chlorine dioxide to kill the tested bacteria at 1 min and 10 min respectively were ≥ 920 mg / L and ≥ 701 mg / L; those with peroxyglutaric acid were ≥ 5500 mg / L and ≥ 5170 mg / L respectively; Were ≥ 9000 mg / L and ≥792 mg / L, respectively. This indicated that the three disinfectants tested had a good killing effect on the four clinically isolated gut bacteria.
