摘要:

为验证碾压消毒垫和驶过消毒池两种常见运输车辆消毒方式对非洲猪瘟病毒（ASFV）的杀灭效果，采用生物学特性和理化特性相近的猪伪狂犬病毒（PRV）疫苗稀释液喷洒运输车辆车轮，测试两种消毒方式的消毒效果。结果显示：车辆碾压消毒垫后0、1、2、3、4、5 min以及驶过消毒池后0、2、5、10 min，车轮可被检测的PRV与表面细菌含量均呈下降趋势，且杀灭效果随时间增加而增强。其中，碾压消毒垫后5 min无法有效杀灭所有PRV，细菌杀灭率为92.5%；驶过消毒池后10 min可有效杀灭所有PRV，细菌杀灭率为98.3%。本研究结果为提高非洲猪瘟疫情应急处置水平和日常防控消毒措施有效性提供了数据支撑。

Abstract:

In order to verify the efficacy of two common disinfection methods for vehicles（including rolling on disinfection pads and driving through disinfection pools）on African swine fever virus（ASFV），the wheels of vehicles were sprayed by vaccine diluent of pseudorabies virus（PRV）with similar biological，physical and chemical characteristics to test the disinfection effects of the two methods. The results showed that the volume of PRV and epiphytic bacteria decreased and the effect increased with time after vehicles rolled on disinfection pads for 0，1，2，3，4 and 5 min，and driving through disinfection pools for 0，2，5 and 10 min. Specifically，all PRV could not be effectively killed in 5 min after rolling on disinfection pads，with the bacterial killing rate of 92.5%；but all PRV could be effectively killed in 10 min after driving through disinfection pools，with the bacterial killing rate of 98.3%. Data support was thus provided by the paper for improving the emergency response to ASF outbreak and the effectiveness of daily prevention，control and disinfection measures.
