A total of 3941 rodents were captured during a 46-month prospective (mark-recapture) study on the ecology of Catarina virus in southern Texas. Antibody reactive against Catarina virus was found in 73 (11.9%) of 611 southern plains woodrats (Neotoma micropus) and none of 3330 other rodents; strains of Catarina virus were isolated from 6 antibody-negative and 9 antibody-positive southern plains woodrats; and the infections in at least 3 southern plains woodrats were chronic. These results affirm the notion that the southern plains woodrat is the principal host of Catarina virus and suggest that Catarina virus infection is highly specific to N. micropus.
在德克萨斯州南部对卡特里那病毒生态学进行的一项为期 46 个月的前瞻性（标记-重捕）研究中，共捕获了 3941 只啮齿动物。在 611 只南方平原林鼠（Neotoma micropus）中，有 73 只（11.9%）对卡特里那病毒有抗体反应，而在 3330 只其他啮齿动物中没有发现；从 6 只抗体阴性和 9 只抗体阳性的南方平原林鼠中分离出了卡特里那病毒株；至少有 3 只南方平原林鼠的感染呈慢性。这些结果证实了南方平原林鼠是卡特里那病毒的主要宿主的观点，并表明卡特里那病毒感染对 N. micropus 具有高度特异性。
