A natural outbreak of Newcastle disease (ND) was reported in a flock of guinea-fowl in Nigeria, affecting 1,029 birds of which 250 (24.3%) died. Paralysis of the legs and wings, coughing, sneezing, white diarrhoea and complete cessation of egg production were observed. Serum samples collected at the onset and during the course of the disease had high ND antibody titres. ND virus was isolated from a pool of brain tissues from diseased guinea-fowl. The ND virus isolate was characterised as a velogenic strain.
据报道，尼日利亚一群珍珠鸡中发生了新城疫自然疫情，1029只鸡受影响，其中250只（24.3%）死亡。观察到腿部和翅膀麻痹、咳嗽、打喷嚏、白色腹泻以及产蛋完全停止。在疾病发作时和病程中采集的血清样本具有高新城疫抗体效价。从患病珍珠鸡的脑组织池中分离出新城疫病毒。分离出的新城疫病毒毒株被鉴定为速发型毒株。
