Infection of Duck Plague Carriers with Pasteurella multocida and P. anatipestifer

Abstract

Mallards (Anas platyrhynchos platyrhynchos) and white pekin ducks (Anas platyrhynchos domesticus) were infected with duck plague virus and challenged with LD20's of Pasteurella multocida and P. anatipestifer. There was no difference between mortality rates of duck plague-infected ducks and controls, suggesting that these organisms do not act synergistically under the conditions of our experiments. There was a difference of about 500-fold between the LD20 of P. multocida for mallards and that for white pekin ducks, indicating that mallards are much more susceptible to avian cholera than white pekin ducks.

A Retrospective Analysis on the Epizootiological Aspects of Outbreaks of Pasteurella anatipestifer Infection in Turkeys in Minnesota

“…However, this infection occurs world-wide in both domestic and wild birds. Endemic infections are restricted to commercial duck and turkey flocks (Mo and Burgess, 1987).…”

“…Adverse environmental conditions or concurrent disease often predispose ducks, swans, and turkeys to outbreaks of this infection (Asplin, 1956;Munday et al, 1966;Mo and Burgess, 1987;Kumar, 1988;Yan Ghazikhanian, 1989). The disease occurs more To whom correspondence should be addressed.…”
