Seroprevalence of Avian Pneumovirus in Minnesota Turkeys

Avian Diseases, 2003
Avian pneumovirus (APV) causes respiratory tract infection in turkeys and was first seen in the United States in Colorado in late 1996. In early 1997, the disease was recognized in Minnesota and caused estimated losses of up to 15 million dollars per year. This virus has not been reported in the other turkey producing states.

Serological evidence for pneumovirus infections in pigs

Veterinary Record, 1998
A serological survey was carried out on pig sera from herds in Northern Ireland to investigate the incidence of reactivity to bovine respiratory syncytial virus (BRsv) antigens. A total of 529 pig sera from 61 herds were tested and 219 (41 per cent) were found to be reactive with BRsv‐infected cell cultures in an indirect immunofluorescence test.

Pneumovirus Infections

2020
Pneumoviruses including human metapneumovirus (HMPV) and respiratory syncytial virus (RSV) are significant causes of respiratory tract infections globally. Children, elderly, and immunocompromised patients are at the greatest risk for developing severe infections, which can have devastating outcomes.

Avian pneumovirus infection of laying hens: Experimental studies

Avian Pathology, 2000
Administration of a virulent strain of avian pneumovirus (APV) to specific pathogen free laying hens by the oculonasal route failed to induce a drop in egg production or any adverse effects on eggshell quality. However, intravenous (i.v.) inoculation of the same strain caused a substantial drop in egg production and a high incidence of soft and thin ...

Appearance of type B avian Pneumovirus in great Britain

Avian Pathology, 1997
A survey in Britain in 1994/95 has shown that in all cases where avian pneumovirus (APV), was detected in turkeys of over 4 weeks of age, the virus was of type B. Oesophageal swabs were collected twice-weekly for up to 14 weeks in seven longitudinal surveys.

Avian Pneumovirus and Its Survival in Poultry Litter

Avian Diseases, 2003
The survival of avian pneumovirus (APV) in turkey litter was studied at different temperature (room temperature, [approximately 22-25 C], 8 C, and -12 C) conditions. Built-up turkey litter from a turkey breeder farm known to be free of APV was obtained and was divided into two portions.

Pathogenic and Immunosuppressive Effects of Avian Pneumovirus in Turkeys

Avian Diseases, 2002
Avian pneumovirus (APV) causes a respiratory disease in turkeys. The virus has been associated with morbidity and mortality due to secondary infections. Our objective was to determine if APV caused immunosuppression in the T-cell or B-cell compartments and to study the pathogenesis of the disease in APV maternal antibody-lacking 2-wk-old commercial ...

Avian Pneumovirus Infections of Turkeys and Chickens

The Veterinary Journal, 2000
Avian pneumoviruses (APVs) cause major disease and welfare problems in many areas of the world. In turkeys the respiratory disease and the effect on egg laying performance are clearly defined. However, in chickens, the role of APV as a primary pathogen is less clear, although it is widely believed to be one of the factors involved in Swollen Head ...
