Fowl cholera is also called avian cholera, avian pasteurellosis and avian hemorrhagic septicemia.
It is the most common pasteurellosis of poultry. As the causative agent is Pasteurella multocida, it is considered to be a zoonosis.
Adult birds and old chickens are more susceptible. In parental flocks, cocks are far more susceptible than hens.
Besides chickens, the disease also concerns turkeys, ducks, geese, raptors, and canaries. Turkeys are particularly sensitive, with mortality ranging to 65%.
The recognition of this pathological condition is of ever increasing importance for differential diagnosis with avian influenza.
