Fowl cholera

In 1879, Pasteur received a bacterial sample from Jean Joseph Henri Toussaint DVM, Professor, Toulouse Veterinary College who had been working with Fowl Cholera.

[7][8] In March 2015, another outbreak of avian cholera killed roughly 2,000 snow geese in northern Idaho while flying their spring migration to Canada.

Blanchong et al.[11] determined that wetlands act as short term reservoirs, recording large amounts of the bacterium in the soil and water through the duration of the outbreak.

Birds with chronic avian cholera, more common in domestic fowl, exhibit prolonged illness with more localized infections.

Chronic infection has been demonstrated in snow geese, and these individuals are believed to be long term migrating reservoirs for the disease.

These often occur in the respiratory tract including the sinuses and pneumatics bones, hock joints, sternal bursa, foot pads, peritoneal cavity and oviducts.

Due to the speed of infection and mortality, birds are in good body condition and do not exhibit the signs of prolonged illness.

The most efficient treatment in breeding flocks or laying hens is individual intramuscular injections of a long-acting tetracycline, with the same antibiotic in drinking water, simultaneously.
