摘　　要：①目的　探讨不同类型戊二醛消毒剂的杀芽孢效果。②方法　采用定量杀菌实验,计算出其杀菌率。③结果　强化中性 戊二醛、强化碱性戊二醛、强化酸性戊二醛消毒剂都含有强化剂,2%的上述3种消毒剂对枯草杆菌黑色变种芽孢作用4小时,对枯草 杆菌黑色变种芽孢的杀灭率达100%,而2%普通戊二醛对枯草杆菌黑色变种芽孢的杀灭作用相对较弱,尤其在有机物存在的条件下, 普通戊二醛对枯草杆菌黑色变种芽孢的杀灭作用较强化的戊二醛明显偏弱。④结论　强化戊二醛的杀灭效果强于普通戊二醛。Objective Tostudg the killing effect of different glutaraldehyde on bacterium gemma. Method Kill ration bacterium test was used in this sludy.The killing rate was calculated according to different glutaroldehyde. Result Neutral,alkaline and acid glutaraldehyde contain some synergetic preparation 100% spores of bacillus subtilis var,niger were killed after 4h contacting with 2% agents mentioned above.The effect of common glutaraldehydt was weaker than synergetic ones,especially when organic substance existed.Conclusion The killig effect of synergetic gluteraldehyde was more powerful than common one.
