context_page_description: Fowl cholera is also called avian cholera, avian pasteurellosis, 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.
context_section_description: In acute cases, a green diarrhea can be an early symptom.
  The most typical symptom, in chronic cases, is the swelling of the wattles. It is more frequent in resistant local breeds. Rather than a general infection, localized infections are more characteristic. These often occur in the respiratory tract including the sinuses and pneumatics bones, hock joints, sternal bursa, foot pads, peritoneal cavity and oviducts.
  In acute cases, the most typical p.m. lesion is the petechiae observed in the epicardial fatty tissue. Necrotic foci on liver are usually found and general hyperemia is common. Due to the speed of infection and mortality, birds are in good body condition and do not exhibit the signs of prolonged illness.
