Abstract

Coues rice rat (Oryzomys couesi), a species abundant throughout Central America, was evaluated experimentally for the ability to serve as an amplifying host for three arboviruses: Patois (Bunyaviridae, Orthobunyavirus), Nepuyo (Orthobunyavirus), and Venezuelan equine encephalitis virus subtype ID (Togaviridae, Alphavirus). These three viruses have similar ecologies and are known to co-circulate in nature. Animals from all three cohorts survived infection and developed viremia with no apparent signs of illness and long-lasting antibodies. Thus, O. couesi may play a role in the general maintenance of these viruses in nature.

摘要

库氏稻鼠(Oryzomys couesi)是中美洲广泛存在的物种,曾被评估是否有能力作为三种虫媒病毒(包括:Patois 病毒、Nepuyo 病毒和委内瑞拉马脑炎病毒亚型 ID)的扩增宿主。这三种病毒具有相似的生态,已知在自然界中共同循环。来自所有三个队列的动物都能存活下来并感染病毒,产生病毒血症,没有明显的疾病迹象和持久的抗体。因此,O. couesi 可能在这些病毒在自然界中的普遍存在中发挥作用。
