The transmission of pathogens from infected to susceptible hosts may occur through contaminated fomites and inanimate objects. This type of transmission depends on the ability of the pathogens to survive in the environment. In this report, we describe the survivability of two avian respiratory viruses, e.g., avian metapneumovirus and avian influenza virus on 12 different porous and nonporous surfaces. The viruses survived on some of the surfaces for up to 6 days postcontamination but not after 9 days. Both viruses survived longer on nonporous surfaces than on porous ones. One of the reasons for poor survival on porous surfaces could be inefficient elution of virus from these surfaces. These results should be helpful in determining how long the premises should be left vacant after an outbreak of these viruses has occurred in poultry houses.
病原体从受感染宿主传播到易感宿主可能通过受污染的污染物和无生命物体发生。这种传播类型取决于病原体在环境中的存活能力。在本报告中，我们描述了两种禽呼吸道病毒，即禽偏肺病毒和禽流感病毒在12种不同的多孔和无孔表面上的存活能力。这些病毒在污染后的某些表面上存活长达6天，但9天后则不能存活。两种病毒在无孔表面上的存活时间都比在多孔表面上长。在多孔表面上存活不佳的原因之一可能是病毒从这些表面洗脱效率低下。这些结果有助于确定家禽舍发生这些病毒疫情后，该场所应空置多长时间。
