Nasal pharyngeal swabs were taken from 400 waterfowl and 37 feral pigeons (Columba livia) and cultured for the presence of Pasteurella multocida, the causative agent of fowl cholera. Blood samples were also taken from these birds and tested for antibodies for P. multocida. Pasteurella multocida was not isolated from any of the birds. However, two of the waterfowl had antibodies for P. multocida. The nasal pharynges of 50 Canada geese (Branta canadensis) were also cultured for Pasteurella anatipestifer, the causative agent of anatipestifer infection. Pasteurella anatipestifer was isolated from 4 of these geese. Experimental inoculation of mallards (Anas platyrhynchos) demonstrated that they are susceptible to anatipestifer infection.
