Fowl Cholera is a serious, highly contagious disease caused by the bacterium Pasteurella multocida in a range of avian species including chickens, turkeys, and water fowl, (increasing order of susceptibility). It is seen worldwide and was one of the first infectious diseases to be recognised, by Louis Pasteur in 1880.
The disease can range from acute septicaemia to chronic and localised infections and the morbidity and mortality may be up to 100%. The route of infection is oral or nasal with transmission via nasal exudate, faeces, contaminated soil, equipment, and people. The incubation period is usually 5-8 days.
The bacterium is easily destroyed by environmental factors and disinfectants, but may persist for prolonged periods in soil. Reservoirs of infection may be present in other species such as rodents, cats, and possibly pigs.
Predisposing factors include high density and concurrent infections such as respiratory viruses.
