对1997年2月在委内瑞拉的一个农场捕获的啮齿动物样本进行了沙粒病毒、抗瓜纳里托病毒（GTOV）抗体和抗皮尔塔尔病毒（PIRV）抗体检测。64只短尾接合鼠（Zygodontomys brevicauda）中31只（48.4%）感染GTOV，1只阿尔斯顿棉鼠（Sigmodon alstoni）感染GTOV，56只阿尔斯顿棉鼠中36只（64.3%）感染PIRV。对野外和实验室数据的分析表明，水平传播是Z.垂直传播是PIRV在短尾鼠体内传播重要方式。Alstoni大鼠。结果还表明，大多数GTOV感染的短尾甘蔗小鼠和大多数PIRV感染的阿尔斯顿棉鼠的身体分泌物和排泄物可能将病毒传播给人类。
Samples from rodents captured on a farm in Venezuela in February 1997 were tested for arenavirus, antibody against Guanarito virus (GTOV), and antibody against Pirital virus (PIRV). Thirty-one (48.4%) of 64 short-tailed cane mice (Zygodontomys brevicauda) were infected with GTOV, 1 Alston's cotton rat (Sigmodon alstoni) was infected with GTOV, and 36 (64.3%) of 56 other Alston's cotton rats were infected with PIRV. The results of analyses of field and laboratory data suggested that horizontal transmission is the dominant mode of GTOV transmission in Z. brevicauda mice and that vertical transmission is an important mode of PIRV transmission in S. alstoni rats. The results also suggested that bodily secretions and excretions from most GTOV-infected short-tailed cane mice and most PIRV-infected Alston's cotton rats may transmit the viruses to humans.
