本研究的目的是阐明委内瑞拉中部平原地区沙粒病毒科（Arenaviridae）的Guanarito病毒和Pirital病毒在啮齿动物中的自然宿主关系。对来自10种不同啮齿动物的607只动物的92株沙粒病毒分离株进行了血清型鉴定。19株冠状病毒分离株来自短尾姬鼠（Zygodontomys brevicauda），73株病毒分离株中有72株（98.6%）来自沙鼠（Sigmodon alstoni）。这些结果表明，这两种同域沙粒病毒在啮齿类动物中的自然关联是高度特异性的，Z。短尾丝虫和阿氏丝虫分别是Guanarito病毒和Pirital病毒的主要啮齿动物宿主。
The objective of this study was to elucidate the natural rodent host relationships of Guanarito and Pirital viruses (family Arenaviridae) in the plains of central Venezuela, Ninety-two arenavirus isolates from 607 animals, representing 10 different rodent species, were characterized to the level of serotype, The 92 isolates comprised 19 Guanarito virus strains and 73 Pirital virus strains. The 19 Guanarito virus isolates were from Zygodontomys brevicauda; 72 (98.6%) of the 73 Pirital virus isolates were from Sigmodon alstoni. These results indicate that the natural rodent associations of these 2 sympatric arenaviruses are highly specific and that Z. brevicauda and S, alstoni are the principal rodent hosts of Guanarito and Pirital viruses, respectively.
