Unstable attenuation of live avian pneumovirus vaccines

2006
Since the 1980s a number of live attenuated type A and B Avian Pneumovirus (APV) vaccines have been developed in Europe and these have generally afforded good protection. All have been produced by repeated passages of field virus in a laboratory culture system to achieve various degrees of attenuation. They are widely used in commercial growing turkeys

Molecular epidemiology of avian pneumovirus strains in Italy

2006
Avian Pneumovirus (APV) infection in Italy is reported from its first appearance in 1987 to present day. The B type virus has been found in different geographical regions but more recently, A type virus has also been detected.

Efficacy of avian pneumovirus vaccines against an avian pneumovirus/Escherichia coli O2:K1 dual infection in turkeys.

The Veterinary record, 2002
The clinical, pathological and microbiological outcome of a challenge with avian pneumovirus (APV) and Escherichia coli O2:K1 was evaluated in turkeys vaccinated with an attenuated APV vaccine and with or without maternally derived antibodies. Two groups of two-week-old poults, one with and one without maternally derived antibodies against APV, were ...
