对在亚利桑那州皮马县采集的28只白喉木(Neotoma Albigula)进行了利什曼原虫的培养和聚合酶链式反应(PCR)筛查。两只啮齿动物培养呈阳性。同工酶分析确定分离株为墨西哥利什曼原虫。两只培养阳性的啮齿动物和另外四只啮齿动物通过聚合酶链式反应被确定为利什曼原虫阳性。这些分离株扩大了美国地方性利什曼病的地理和生态范围，并代表了一种新的宿主记录。
Twenty-eight white-throated woodrats (Neotoma albigula) collected in Pima County, Arizona were screened for Leishmania using culture and the polymerase chain reaction (PCR). Two rodents were culture positive. Isoenzyme analysis determined the isolates to be Leishmania mexicana. The two culture-positive and four additional rodents were determined to be Leishmania-positive by the PCR. These isolates extend the geographic and ecologic range of enzootic leishmaniasis in the United States and represent a new host record.
