In birds, P. multocida causes avian or fowl cholera disease; a significant disease present in commercial and domestic poultry flocks worldwide, particularly layer flocks and parent breeder flocks. P. multocida strains that cause fowl cholera in poultry typically belong to the serovars 1, 3, and 4. In the wild, fowl cholera has been shown to follow bird migration routes, especially of snow geese.
