Serological monitoring of avian pathogens in layer farms using sentinel birds, 2: Pathogenic viruses
Specific-pathogen-free (SPF) chickens were housed as sentinel birds in three layer farms for 12 or 17 months together with commercial laying hens to monitor avian encepharomyelitis virus (AEV), infectious bronchitis virus (IBV), egg-drop syndrome virus (EDSV), fowl adenovirus (FAV), avian reovirus (...

Zusammenfassung: | Specific-pathogen-free (SPF) chickens were housed as sentinel birds in three layer farms for 12 or 17 months together with commercial laying hens to monitor avian encepharomyelitis virus (AEV), infectious bronchitis virus (IBV), egg-drop syndrome virus (EDSV), fowl adenovirus (FAV), avian reovirus (ARV), and infectious bursal disease virus (IBDV). Antibodies to IBV were detected in sentinel birds of every farm a few days after their introduction. Antibodies to FAV, ARV and AEV were detected in two farms, and the times of sero-conversion differed by farm. Antibody to IBDV was detected in sentinel birds of only one farm. Antibody to EDSV was not detected in any farm. These results suggest that SPF chickens may be useful for monitoring avian virus infections in layer farms. |
