Freeze Dried Live Vaccine – Fowl Pox – SPF origin

FOWL POX

Fowl pox is a mild to severe, slow-developing disease of birds caused by avipoxvirus. The disease is characterized by wart-like nodules on the skin and diphtheritic necrotic membranes lining the mouth and upper respiratory system. In domestic poultry, infections cause an economically important disease. Active immunity develops following natural infection or after immunization with live vaccines. Replication of the vaccinal virus at the inoculation site results in development of a local inflammatory process also known as vaccinal ‘take’. The presence of vaccinal ‘take’ is an indication that the bird was vaccinated.
