Fowl Pox (FP)
A relatively slow spreading infectious viral disease of poultry of all ages.
Almost all birds of all ages are susceptible. Pigeon Pox can also infect chickens and turkeys.
FP is world wide and is prevalent wherever poultry are raised. It is one of the earliest recognized diseases of poultry and was identified as a virus in 1902.
It is transmitted by air or infected mosquito and possibly by ingestion of infective scabs.
Once airborne in the a poultry house, the virus can enter the blood stream through conjunctiva of the eye, skin sounds, or respiratory. Typical FP lesions will develop. Mosquitoes become infected from feeding on birds with FP in the blood stream.
Clinical signs are classic raised wart-like lesions on unfeathered areas (head, legs, vent, etc). Unthrift ness, retarded growth, and slow spread through the flock are typical FP symptoms. The lesions will heal (after 2 weeks) If the scab is removed before healing is complete, the surface beneath the scab is raw and bleeding.
There are two types of lesions: dry form (skin) lesions and wet form (diphtheritic) lesions occur in the mouth, pharynx, larynx and trachea and cause canker like lesions and swelling. You can vaccinate with FP vaccine to stop FP outbreaks. Use wing-web (WW) vaccination method for chickens and feather follicle method for turkeys older than 8 weeks.
Treat pos lesions in pet birds topically with silver nitrate and give an antibiotic in water for 2 to 3 days to combat bacterial infections. FP outbreaks in poultry confined to houses can be controlled by spraying to kill mosquitoes. If FP is endemic in the area, vaccinate replacement birds.
