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.
绿头鸭（绿头野鸭指名亚种）和北京鸭（绿头野鸭家鸭亚种）感染鸭瘟病毒后，再用多杀性巴氏杆菌和鸭疫里默氏杆菌的20%致死剂量进行攻毒。感染鸭瘟的鸭子和对照鸭子的死亡率没有差异，这表明在我们的实验条件下，这些病原体不会产生协同作用。多杀性巴氏杆菌对绿头鸭的20%致死剂量与对北京鸭的20%致死剂量之间相差约500倍，这表明绿头鸭比北京鸭对禽霍乱更易感。
