Between July and September 2017, samples collected from six unvaccinated chickens in Namibia were shown to be positive for infectious bursal disease virus (IBDV) by RT-PCR. Partial sequence and phylogenetic analysis of the VP1 and VP2 genes from six viruses revealed that they all belong to the very virulent pathotype (Genogroup 3) and are genetically very similar to IBDVs identified in neighbouring Zambia. This is the first molecular characterisation of IBDV in Namibia and has implications on the control and management of the disease in the country.
2017年7月至9月期间，从纳米比亚6只未接种疫苗的鸡身上采集的样本经逆转录聚合酶链反应（RT-PCR）检测，显示传染性法氏囊病病毒（IBDV）呈阳性。对6种病毒的VP1和VP2基因进行的部分序列及系统发育分析表明，它们均属于超强毒力型（基因群3），并且在基因上与在邻国赞比亚鉴定出的IBDV非常相似。这是纳米比亚IBDV的首次分子特征描述，对该国该疾病的防控和管理具有重要意义。
