Nasal turbinates or swabs were collected from wild ducks, geese, owls, sparrows, swallows, and starlings and from sentinel ducks placed next to turkey farms experiencing avian pneumovirus (APV) infections and were analyzed for APV genome and infectious particles. APV RNA was detected in samples examined from geese, sparrows, and starlings. APV RNA and antibodies were also detected in two different groups of sentinel ducks. Infectious APV was recovered from sentinel duck samples. The APV M gene isolated from the wild birds had over 96% predicted amino acid identity with APV/Minnesota 2A, which was isolated earlier from domestic turkeys showing respiratory illness, suggesting that wild birds may be involved in spreading APV infection.
从野鸭、鹅、猫头鹰、麻雀、燕子和椋鸟身上采集鼻甲或拭子,并从紧邻感染禽肺病毒(APV)的火鸡养殖场的哨兵鸭身上采集样本,对其进行APV基因组和感染性颗粒分析。在从鹅、麻雀和椋鸟检测的样本中发现了APV RNA。在两组不同的哨兵鸭中也检测到了APV RNA和抗体。从哨兵鸭样本中分离出了感染性APV。从野生鸟类中分离出的APV M基因与之前从出现呼吸道疾病的家养火鸡中分离出的APV/明尼苏达2A预测氨基酸同一性超过96%,这表明野生鸟类可能参与了APV感染的传播。
