摘要 通过设计过硫酸氢钾复合物粉对马腺疫链球菌兽疫亚种及多杀性巴氏杆菌的定量、定性杀灭试验,对该消毒剂的消毒效果进行研究。结果显示:过硫酸氢钾复合物粉1 600倍稀释时对马腺疫链球菌兽疫亚种的杀菌率为100%;3 200倍稀释时对多杀性巴氏杆菌杀菌率为100%。过硫酸氢钾复合物粉对马腺疫链球菌兽疫亚种的最低有效浓度为3 200倍稀释,该浓度的最短作用时间为60 min;对多杀性巴氏杆菌的最低有效浓度为3 200倍稀释,该浓度的最短作用时间为30 min。

Abstract The disinfection effect of the disinfectant was studied by observing the quantitative and qualitative killing test of potassium monopersulfate triple salt composite powder on Streptococcus equi subsp. zooepidemicus and Pasteurella multocida . The results showed that the bactericidal rate of potassium monopersulfate triple salt composite powder to S.equi subsp. zooepidemicus was 100% at 1 600 times dilution and to P.multocida was 100% at 3 200 times dilution. The minimum effective concentration of potassium monopersulfate triple salt composite powder to S.equi subsp. zooepidemicus was 3 200 times of dilution, and the shortest action time of this concentration was 60 min; the minimum effective concentration to P.multocida was 3 200 times of dilution, and the shortest action time of this concentration was 30 min.

動物性疫病是影响当代养殖业发展的主要因素,我国提倡“预防为主,防治结合”的方针政策,使用消毒剂对畜舍及其周围环境消毒是预防疫病必不可少的措施[1]。过硫酸氢钾复合物粉是由过硫酸氢钾KHSO5(PMS)、硫酸氢钾KHSO4和硫酸钾K2SO4这3种物质组成,KHSO5为其主要成分,具有强氧化性,易溶于水[2],杀菌原理主要是利用单过硫酸氢钾的特殊氧化能力和链式反应,即在水中不断产生新生态氧、次氯酸、自由羟基、过氧化氢,通过新生态氧和自由羟基的氧化作用可以改变细胞膜的通透性使之破裂,从而达到杀灭病原微生物的目的[3]。过硫酸氢钾复合物粉作为一种广谱、高效、低毒的兽用复方消毒剂被广泛关注[4]。为观察验证过硫酸氢钾复合物粉的消毒效果,笔者拟研究过硫酸氢钾复合物粉对马腺疫链球菌兽疫亚种及多杀性巴氏杆菌的消毒效果。……
