对源自巴西牛的77株狂犬病毒（RV）进行了遗传鉴定。对这些分离株的部分核蛋白基因序列进行了系统发育和地理分析。与吸血蝙蝠相关的RV群聚集在一起的牛分离株进一步细分为9个遗传亚群。这些亚群广泛分布在低地地区，其中一些亚群被山脉隔开。此外，山地种群的分离程度与海拔高度有关。这些结果表明，牛狂犬病起源于几个区域定义的变异，这表明其地理分布与吸血蝙蝠种群的地理分布有关。
Seventy-seven rabies virus (RV) isolates originating from Brazilian cattle were genetically characterized. Partial nucleoprotein gene sequences of these isolates were phylogenetically and geographically analyzed. Cattle isolates, which clustered with the vampire bat-related RV group, were further subdivided into nine genetic subgroups. These subgroups were distributed widely in lowland regions, with some subgroups separated from each other by mountain ranges. In addition, separation of the groups in mountainous regions was correlated with altitude. These results indicate that cattle rabies is derived from several regionally-defined variants, which suggests that its geographical distribution is related to that of the vampire bat population.
