Susceptibility of ducks to avian pneumovirus of turkey origin

American Journal of Veterinary Research, 2001
Abstract Objective—To determine the susceptibility of ducks to avian pneumovirus (APV) of turkey origin. Animals—30 Pekin ducks that were 2 weeks old. Procedure—Ducks were assigned to 3 groups (10 ducks/group). Ducks of groups 1 and 2 were inoculated (day 0) with 200 µl of cell-culture fluid containing APV of turkey origin

Characterization of Italian avian pneumovirus strains

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. To establish the identity and heterogeneity among the APV strains that circulated in Italy from 1987 to 2004, the nucleotide ...

AVIAN PNEUMOVIRUS IN ITALY

2004
APV infection in Italy is reported from its first appearance in 1987 to present day. Serological, virological and molecular testing have been applied during one-off and longitudinal studies of turkeys and chickens. The B type virus has been found in different geographical regions but more recently, A type virus has also been detected.

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. To establish the identity and heterogeneity among the APV strains that circulated in Italy, the nucleotide sequences of the ...

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 ...
