2005年至2007年，在加州的约塞米蒂国家公园，调查了不同小型哺乳动物中的蜱虫、跳蚤和媒介传播的病原体。在3年的时间内，共收集了450个独特的捕获的小型哺乳动物，产生了16种跳蚤和10种蜱虫，包括已知的载体的无浆体phagocytophilum和伯氏疏螺旋体和鼠疫。对A.嗜吞噬细胞菌，斑点热群立克次体属，B。burgdorferi和鼠疫耶尔森氏菌（Yersinia pest）。A.在所有受试野生小型哺乳动物中，12.1%的动物暴露于嗜吞噬细胞菌，10个物种的动物血清反应呈阳性，特别是贝尔丁地松鼠（Spermophilus beldingi）、跳鼠（Zapus princeps）和田鼠（Microtus sp.）。斑点热群立克次体在所有测试的小型哺乳动物中，有13.9%的动物受到了接触，其中8个物种的动物血清反应呈阳性。此外，在5个试验种属中，37.0%的啮齿动物为B血清阳性。burgdorferi。没有人血清阳性的Y。鼠疫没有动物对任何检测的病原体呈聚合酶链反应阳性。这些结果为今后研究和预测约塞米蒂国家公园新出现的病媒传播疾病提供了基线数据，并为加州的蜱虫和跳蚤增加了已知的范围和宿主物种。
Ticks, fleas, and vector-borne pathogens were surveyed in diverse small mammals in Yosemite National Park, California, from 2005 to 2007. A total of 450 unique captures of small mammals was collected during a 3-yr period and yielded 16 species of fleas and 10 species of ticks, including known vectors of Anaplasma phagocytophilum and Borrelia burgdorferi and plague. Serology was performed for A. phagocytophilum, spotted fever group Rickettsia spp., B. burgdorferi, and Yersinia pest is. A. phagocytophilum exposure was identified in 12.1% of all wild small mammals tested, with seropositive animals in 10 species, notably Belding's ground squirrels (Spermophilus beldingi), jumping mice (Zapus princeps), and voles (Microtus sp.). Spotted fever group Rickettsia spp. exposure was detected in 13.9% of all small mammals tested, with seropositive animals in eight species. Additionally, 37.0% of rodents in five species tested were seropositive for B. burgdorferi. No individuals were seropositive for Y. pestis. No animals were polymerase chain reaction positive for any pathogen tested. These results provide baseline data for future research and prediction of emerging vector-borne disease in Yosemite National Park, as well as adding to the known ranges and host species for tick and fleas in California.
