Nine previously vaccinated turkeys were inoculated intravenously with Pasteurella anatipestifer, and blood samples were taken periodically to evaluate the potential of chronically infected turkeys to serve as reservoirs of infection for blood-feeding arthropod vectors. Vertebral osteomyelitis (spondylitis), as yet unreported in the literature in association with infection with the organism, was found in the thoracic vertebrae of five out of nine inoculated turkeys, and P. anatipestifer was isolated from the thoracic vertebrae of three of the five. The organism was isolated from the peripheral blood of six turkeys 24 hours postinoculation and from the peripheral blood of one turkey 7 days postinoculation. The organism was also isolated from the heart blood of two birds at necropsy--from one at 21 days and, following an intramuscular injection of dexamethasone, from the other turkey at 38 days postinoculation.
给9只先前已接种疫苗的火鸡静脉注射鸭疫里默氏杆菌，定期采集血样，以评估慢性感染火鸡作为吸血节肢动物传播媒介感染源的可能性。在文献中尚未有该病原体感染相关的脊椎骨髓炎（脊柱炎）报道，在9只接种火鸡中的5只的胸椎中发现了这种情况，并且从这5只中的3只的胸椎中分离出了鸭疫里默氏杆菌。接种后24小时，从6只火鸡的外周血中分离出该病原体，接种后7天，从1只火鸡的外周血中分离出该病原体。在尸检时，还从2只禽类的心血中分离出该病原体——1只在接种后21天，另1只在接种后38天经肌肉注射地塞米松后分离出该病原体。
