摘要
目的 比较9种常用消毒剂对减毒牛分枝杆菌、炭疽杆菌弱毒株芽孢和布鲁菌弱毒株的杀灭效果。方法采用悬液定性杀菌试验,观察84消毒液、碘伏、二溴海因、过氧化氢溶液、乙醇、石碳酸、氯己定、苯扎溴铵和戊二醛分别对3种细菌作用5和45 min的杀灭效果,采用细菌培养进行效果评价。结果 0.55%84消毒液、0.5%碘伏、3%过氧化氢溶液、75%乙醇和2%戊二醛等消毒液作用5 min能有效杀灭减毒牛分枝杆菌,而0.1%二溴海因和0.3%苯扎溴铵作用时间延长至45 min,仍无明显杀灭效果。0.55%84消毒液、0.5%碘伏、3%过氧化氢溶液须进行长时间浸泡对炭疽杆菌弱毒株芽孢有一定的杀灭效果。75%乙醇、5%石碳酸、0.2%氯己定和0.3%苯扎溴铵等作用45 min无法完全杀灭炭疽杆菌弱毒株芽孢。结论 75%乙醇和0.55%84消毒液对减毒牛分枝杆菌和布鲁菌弱毒株均有较好的杀灭效果,而对炭疽杆菌弱毒株芽孢则无明显的杀灭效果。
Objective To compare the killing effects of nine commonly used disinfectants on attenuated Mycobacterium bovis,Bacillus anthracis attenuated strains spores and Brucella spp attenuated strains.Methods The suspension qualitative bactericidal test was used to detect the effect of 84 disinfectant,0.5% iodophor,50% dibromohydantoin,30% hydrogen peroxide solution,75% ethanol,50% carbolic acid,0.2% chlorhexidine,3% benzalkonium bromide and 2% glutaraldehydee on three bacteria for 5 and 45 min,respectively.Bacterial culture method was used to evaluate the killing effect of each disinfectant.Results 0.55% 84 disinfectant,0.5% iodophor,3% hydrogen peroxide solution,75% ethanol and 2% glutaraldehyde could effectively kill attenuated Mycobacterium bovis after 5 min,while 0.1% dibromohain and 0.3% benzalammonium bromide had no obvious killing effect even if time was extended to 45 min.Similarly,0.55% 84 disinfectant solution,0.5% iodophor and 3%hydrogen peroxide solution had a certain efficacy on Bacillus anthracis attenuated strains spores only when incubating for a long time.75% ethanol,5% carbonic acid,0.2% chlorhexidine and 0.3% benzalammonium bromide could not completely kill Bacillus anthracis spores incubating for 45 min.Conclusions 75% ethanol and 0.55% 84 disinfectant have good killing effect on attenuated Mycobacterium bovis and Brucella spp attenuated strains,but have no obvious killing effect on Bacillus anthracis attenuated strain spores.
