这项研究的目的是确定一种主要与德克萨斯州南部平原林木(Neotoma Micropus)相关的Arena病毒与其他新大陆Arenav的分类关系。糖蛋白前体氨基酸序列和核衣壳蛋白氨基酸序列的独立分析结果表明，德克萨斯州南部的ArenaVirus是一个新的病毒(建议的种名为Catarina Virus)，与白水Arroyo病毒亲缘关系最近，与新墨西哥州西北部的白喉树(Neotoma Albigula)主要相关。总之，卡特琳娜病毒和白水Arroyo病毒之间的密切系统发育关系以及这些病毒物种与同属啮齿动物物种的关联支持了这样的观点，即一些新大陆地区的Arenaa病毒的主要宿主关系是Arenaviridae病毒科和啮齿科鼠科动物之间长期共同进化关系的产物。
The purpose of this study was to define the taxonomic relationship of an arenavirus principally associated with the southern plains woodrat (Neotoma micropus) in southern Texas to other New World arenaviruses. The results of independent analyses of glycoprotein precursor amino acid sequences and nucleocapsid protein amino acid sequences indicated that the arenavirus in southern Texas is novel (proposed species name Catarina virus) and phylogenetically most closely related to Whitewater Arroyo virus, which is principally associated with the white-throated woodrat (Neotoma albigula) in northwestern New Mexico. Together, the close phylogenetic relationship between Catarina virus and Whitewater Arroyo virus and the association of these viral species with congeneric rodent species support the notion that the principal host relationships of some New World arenaviruses are a product of a long-term shared evolutionary relationship between the virus family Arenaviridae and the rodent family Cricetidae.
