摘要
为探索亚洲狂犬病毒可能的起源、亲缘关系和进化动力学,我们研究了该地区200个狂犬病株完整的核蛋白(N)的基因序列。系统发生的证据表明,所分析的亚洲的这些狂犬病毒都属于基因1型,可继续区分为5个不同的亚群。我们的地理空间和时间分析表明,中国似乎是当代亚洲狂犬病毒的主要来源。理解狂犬病的传播和相关的人类活动,如狗的流动状况,可能有助于亚洲各国通过协同的努力或规划来实现在亚洲控制和消除狂犬病的目标。
abstract
Rabies in Asia is emerging as a serious public health issue. To explore the possible origin, phylogenetic relationships, and evolutionary dynamics of Asian Rabies viruses (RABV), we examined 200 complete nucleoprotein (N) gene sequences from RABV isolates in the region. Phylogeny supported the classification of Asian RABVs into five distinct clusters in lyssavirus genotype 1. Our geospatial and temporal analyses demonstrated that China appears to be the prime source of Asian RABVs. Understanding of rabies transmission and associated human activities, such as dog translocation, can help rabies control and elimination in Asia through collaborative efforts or programs.
