畜禽生产区常用消毒剂杀菌效果监测方法探讨

An Inquiry into the Detection Method of the Antiseptic Effect of Commonly Used Disinfectant in Livestock and Poultry Production Area

本试验以菌毒敌、烧碱等常用消毒剂为代表,监测它们在人车进出畜禽生产区消毒池中的杀菌抑菌效果,对已知大肠杆菌的最小抑菌浓度及其有效浓度持续时间的变化情况,测得烧碱的最小抑菌浓度为0.25%、菌毒敌为0.16%,按菌毒敌使用说明配制的浓度在消毒池中持续到第九天仍有较好的抑菌效果。

With the commonly used disinfectant,such as Jun-Du-Di and caustic soda,as examples,this experiment detect their antiseptic effect in livestock and poultry areas and the minimum inhibitory concentration（MIC） against ascherichia,together with the change of the lasting time of effective concentration.The result is that the MIC of caustic soda is 0.25%,that of Jun-Du-Di is 0.16%,and the concentration in accordance with the instructions of Jun-Du-Di lasts its antiseptic effect to the 9th day.
