Three of thirteen Oryzomys acritus, Emmons and Patton 2005 (Rodentia: Muridae: Sigmodontinae) and 3 of 17 Oryzomys nitidus, Thomas 1884, collected from Noël Kempff National Park, Bolivia, from 2002 to 2005, tested positive for Leishmania (Leishmania) amazonensis or L. (L.) mexicana and negative for Leishmania (Viannia) spp. using the polymerase chain reaction (PCR). Based on previous records of L. (L.) amazonensis in humans, rodents, and sand flies from Bolivia, and the geographic distributions of L. (L.) amazonensis and L. (L.) mexicana, it was concluded that the Oryzomys were infected with L. (L.) amazonensis. These results identify two additional species of Oryzomys as hosts of L. (L.) amazonensis, and identify an ecological region of Bolivia where L. (L.) amazonensis is enzootic.
2002年至2005年期间，从玻利维亚的诺埃尔·肯普夫国家公园采集的13只阿氏稻鼠（埃蒙斯和巴顿，2005年；啮齿目：鼠科：稻鼠亚科）中的3只，以及17只亮稻鼠（托马斯，1884年）中的3只，经聚合酶链反应（PCR）检测，利什曼原虫（亚马逊利什曼原虫）或墨西哥利什曼原虫呈阳性，而维氏利什曼原虫属呈阴性。根据玻利维亚人类、啮齿动物和白蛉中亚马逊利什曼原虫的既往记录，以及亚马逊利什曼原虫和墨西哥利什曼原虫的地理分布，得出稻鼠感染了亚马逊利什曼原虫的结论。这些结果确定了另外两种稻鼠为亚马逊利什曼原虫的宿主，并确定了玻利维亚亚马逊利什曼原虫为地方流行的一个生态区域。
