Avian metapneumovirus

Avian Metapneumoviruses (AMPV) consist of nine serogroups of avian paramyxoviruses that affect chickens and turkeys. The most important AMPV in poultry is Newcastle disease virus (APMV-1).

APMVs replicate in the respiratory tract and the reproductive tract. It initially causes respiratory disease in infected birds and may also cause drops in egg production in layers and breeders.
