Blood samples from 4893 cricetid rodents were tested for antibody (immunoglobulin G) to Whitewater Arroyo virus and Amaparí virus to extend our knowledge of the natural host range and geographical distribution of Tacaribe serocomplex viruses in North America. Antibodies to arenaviruses were found in northern pygmy mice (Baiomys taylori), woodrats (Neotoma spp.), northern grasshopper mice (Onychomys leucogaster), oryzomys (Oryzomys spp.), deermice (Megadontomys nelsoni and Peromyscus spp.), harvest mice (Reithrodontomys spp.), and cotton rats (Sigmodon spp.) captured in New Mexico, Texas, or Mexico. Comparison of endpoint antibody titers to Whitewater Arroyo virus and Amaparí virus in individual blood samples indicated that the Tacaribe complex viruses enzootic in Texas and Mexico are antigenically diverse.
检测了来自 4893 只仓鼠科啮齿动物的血液样本,以检测针对白水溪病毒和阿帕里病毒的抗体(免疫球蛋白 G),以扩展我们对北美塔卡里伯病毒复合血清群的自然宿主范围和地理分布的了解。在北小囊鼠(Baiomys taylori)、林鼠(Neotoma spp.)、北草地田鼠(Onychomys leucogaster)、稻鼠(Oryzomys spp.)、鹿鼠(Megadontomys nelsoni 和 Peromyscus spp.)、收获鼠(Reithrodontomys spp.)和棉鼠(Sigmodon spp.)中发现了针对沙卡里伯病毒复合群的抗体,这些啮齿动物分别来自新墨西哥州、德克萨斯州或墨西哥。比较单个血液样本中针对白水溪病毒和阿帕里病毒的终点抗体滴度表明,在德克萨斯州和墨西哥流行的塔卡里伯病毒复合群在抗原上具有多样性。
