Abstract:
Avian metapneumovirus disease is an emerging viral infection caused by avian metapneumovirus (aMPV), an infectious disease characterized by acute upper respiratory tract infection and a severe decrease in egg production and eggshell quality of laying chicken. aMPV causes septicemic and exudative diseases of domestic ducks, geese and turkeys, leading to economically devastating to poultry industries. aMPV can infect chickens, ducks, pigeons and other birds, and is widely prevalent around the world, causing huge economic losses to the poultry industry. In this paper, we review aMPV in terms of genomic structure and its encoded proteins, epidemiological status, pathogenicity, infection-induced host immune response, and its diagnostic techniques and vaccines to provide a scientific basis for the diagnosis and prevention of the disease in the future.
