Survival of Highly Pathogenic Avian Influenza H5N1 Virus in Tissues Derived from Experimentally Infected Chickens.

ABSTRACT: Eurasian lineage highly pathogenic avian influenza (HPAI) H5N1 virus has been a severe threat to the poultry industry since its emergence in 1996. The carcass or tissues derived from infected birds may present the risk of the virus spreading to humans, animals, and the surrounding environment. In this study, we investigated the survival of the virus in feather, muscle, and liver tissues collected from six chickens (Gallus gallus) experimentally infected with HPAI H5N1 virus. The tissues were stored at +4°C or +20°C, and viral isolation was performed at different times for 360 days. The maximum periods for viral survival were observed in samples stored at +4°C in all tissue types and were 240 days in feather tissues, 160 days in muscle, and 20 days in liver. The viral infectivity at
