摘要

使用化学消毒剂灭活禽流感病毒(AIVs)是疫情期间必不可少的生物安全措施。消毒过程的效率取决于消毒剂的种类和有机物的存在与否。目前还不清楚AIV的致病类型是否会影响其对特定消毒剂的耐受性。在这里,我们评估了福尔马林和苛性钠在存在和不存在湿粪便的情况下对高(H5N1)和低(H9N2)致病性aiv的效率。结果表明,两种消毒剂的有效性取决于目标病毒,低致病性H9N2病毒普遍比高致病性H5N1病毒更容易消毒。湿粪便对消毒作用的影响与病毒和接触时间有关。本研究强调了在开始消毒过程之前消除粪便物质的重要性,并指出在选择合适的消毒剂时,消毒剂类型和aiv病原体类型的影响。

Inactivation of Avian Influenza Viruses by Chemical Disinfectants and the Influence of Faecal Matter
Inactivation of avian influenza viruses (AIVs) using chemical disinfectants is an indispensable biosecurity measure during outbreaks. The efficiency of disinfection process depends on disinfectant type and presence or absence of organic matter. It is also not clear whether AIV pathotype could influence its tolerability to a given disinfectant. Here, we assessed the efficiency of formalin and caustic soda against high (H5N1) and low (H9N2) pathogenic AIVs in the presence and absence of wet faeces. Our results showed that the effectiveness of both disinfectants depends on the target virus with the low pathogenic H9N2 virus being generally more susceptible to disinfection than the high pathogenic H5N1 virus. Wet faeces slightly influenced disinfection action in a virus- and contact time- dependent manner. This study highlights the importance of eliminating faecal matter before initiating a disinfection process and indicates the influence of disinfectant type and AIVs pathotype when selecting the appropriate disinfectant.
