大绒鼠（Eothenomys miletus）是我国西南地区特有的啮齿动物，也是人畜共患病的主要宿主。根据2001 - 2013年在39个地点采集的2463只田鼠的宿主样本，对E.米利都在其整个分布范围内。结果表明，共检出体表寄生虫71895只，隶属于320种（蚤30种、吸虱9种、革螨106种、恙螨175种），其感染率（87%）、平均丰度（29.19）和平均强度（33.69）均较高。在E.优势种为蚤目（蚤目：Hystrichopsyllidae）的方栉眼蚤（Ctenophthalmus quadratus）和恙螨目（Trombidiformes：Trombiculidae）的小盾纤恙螨（Leptotrobidium scutellare），是我国人畜共患病的主要媒介。优势种均呈聚集分布。雄性田鼠比雌性田鼠携带更多种类的寄生虫。恙螨是田鼠体表最丰富的螨类，其感染率与平均丰度呈正相关（r = 0.73; P < 0.05）。E.米利都很有可能窝藏大量的体外寄生虫，具有高度的物种多样性和高感染率。田鼠的性别影响体外寄生虫的感染。
The Yunnan red-backed vole Eothenomys miletus (Rodentia: Cricetidae) is an endemic rodent species and reservoir host of zoonoses in southwest China. Based on a large host sample (2463 voles collected from 39 localities between 2001 and 2013), a general analysis of four categories of ectoparasite (fleas, sucking lice, chigger mites and gamasid mites) on E. miletus across its entire range of distribution was made. This analysis identified a total of 71 895 ectoparasites belonging to 320 species (30 species of flea, 9 of sucking louse, 106 of gamasid mite and 175 of chigger mite) with a high prevalence (87%), mean abundance (29.19) and mean intensity (33.69). Of the 18 vector species of zoonoses found on E. miletus, the flea Ctenophthalmus quadratus (Siphonaptera: Hystrichopsyllidae) and chigger mite Leptotrombidium scutellare (Trombidiformes: Trombiculidae) were the dominant species; these are the main vectors of zoonoses in China. All of the dominant parasite species showed an aggregated distribution pattern. Male voles harboured more species of parasite than females. Chigger mites represented the most abundant species group on voles and their prevalence was positively correlated with mean abundance (r = 0.73; P < 0.05). As a single rodent species, E. miletus has a high potential to harbour abundant ectoparasites with high species diversity and high rates of infestation. The sex of the vole affects ectoparasite infestation.
