摘要
目的研究消毒剂对副溶血弧菌和创伤弧菌的杀灭作用,为海洋弧菌致创伤感染的预防消毒提供依据。方法用悬液定量杀菌试验方法对四种常用化学消毒剂杀灭两种海洋弧菌的效果进行了观察。结果用有效碘50mg/L的聚维酮碘溶液对悬液内两种海洋弧菌作用3 min,平均杀灭率均达到99.999%以上。用含300 mg/L的复方消毒剂和双癸基甲基氯化铵消毒液对悬液内创伤弧菌和副溶血弧菌作用5 min,平均杀灭率均在99.999%以上。用200 mg/L的过氧乙酸消毒液对悬液内创伤弧菌和副溶血弧菌作用1 min,可达到完全杀灭。结论四种消毒剂在较低浓度下对两种海洋弧菌杀灭效果较好,以聚维酮碘杀菌效果最好。
Objective To study the efficacy of disinfectants in killing pathogenic V. parahaemolyticus and V. vulnificus.Method Suspension quantitative germicidal test was used to observe the efficacy of 4 common chemical disinfectants in killing two species of marine vibrio. Results Povidone iodine solution containing available iodine 50 mg/L with 3 min contact time killed 99. 999% of V. parahaemolyticus and V. vulnificus. Both compound disinfectant solution containing chlorhexidine and glutaldehyde and didecyl methyl ammonium chloride（DMAC） containing 300 mg/L with 5 rain contact time killed 99. 999% of the 2 pathogens. 200 mg/L peracetic acid with lmin contact time could completely kill both of the two pathogens. Conclusions The 4 disinfectants at relatively low concentrations have good efficacy in killing 2 marine vibrios. Povidone iodine has the best germicidal efficacy and is an ideal disinfectant to vibrio.
