Abstract
The Marek's disease virus vaccine virus, Rispens/CVI988, in feathers of commercial flock was detected from 4 to 7â¯days and for at least 3â¯months post-vaccination, until the survey stopped. As the drinking water route was newly adopted for Infectious laryngotracheitis vaccination, one or two vaccine doses/bird were administered. The virus uptake was detected in feathers between 2 and 20â¯days-post-vaccination. With a doubled vaccine dose the positivity bird rate was higher. For the first time the chicken anemia vaccine virus presence in chicken feathers was demonstrated between 14 and 35â¯days-post-vaccination. No previous studies were available, thus in parallel to feathers the vaccine virus was demonstrated in the livers and spleens. The turkey meningoencephalitis vaccine virus uptake in turkey feather-pulps is even more innovative because this is the first turkey virus amplified from feather-pulps. The vaccine virus presence resemble the kinetics of the other 3 viruses, 3-21â¯days-post-vaccination. Detecting the specific antibodies following vaccination possessed a lower sensitivity than vaccine virus demonstration in feathers. In summary, the presented assay can be adopted for the quality evaluation of the vaccination process in poultry.
