啮齿动物是跳蚤、虱子、蜱虫和螨虫等各种体外寄生虫类群的已知宿主。南非以其动物多样性而闻名，但关于野生啮齿动物相关寄生虫多样性的研究发表得很少。通过关注野生动物 - 人类/家畜的接触面，本研究旨在记录布氏沙鼠（Gerbilliscus leucogaster）体外寄生虫的多样性和感染程度，并确定体外寄生虫感染参数与宿主及栖息地因素之间的关系。在2014 - 2020年期间，在两种栖息地类型（自然栖息地和农业栖息地）中捕获了啮齿动物（n = 127只）。收集到了由21个属代表的、属于5个分类群（跳蚤、吸虱、蜱虫、中气门螨和恙螨）的32种体表动物的6500多个个体。中气门螨和虱子数量最多，跳蚤和中气门螨是最普遍的类群。在繁殖活跃的雄性啮齿动物身上，跳蚤和中气门螨的数量以及中气门螨的物种丰富度明显高于雌性啮齿动物。只有蜱虫与栖息地类型显著相关，与农业栖息地相比，自然栖息地中的啮齿动物身上的蜱虫数量明显更多，蜱虫种类也更多。我们得出结论，与宿主密切相关的体外寄生虫（跳蚤和螨虫）的感染程度受宿主相关因素影响，而大部分时间生活在外部环境中的体外寄生虫（蜱虫）的感染程度则受栖息地类型影响。
Rodents are known hosts for various ectoparasite taxa such as fleas, lice, ticks and mites. South Africa is recognized for its animal diversity, yet little is published about the parasite diversity associated with wild rodent species. By focusing on a wildlife-human/domestic animal interface, the study aims to record ectoparasite diversity and levels of infestations of the Bushveld gerbil, Gerbilliscus leucogaster, and to establish the relationship between ectoparasite infestation parameters and host- and habitat factors. Rodents (n = 127) were trapped in 2 habitat types (natural and agricultural) during 2014–2020. More than 6500 individuals of 32 epifaunistic species represented by 21 genera and belonging to 5 taxonomic groups (fleas, sucking lice, ticks, mesostigmatan mites and trombiculid mites) were collected. Mesostigmatan mites and lice were the most abundant and fleas and mesostigmatan mites the most prevalent groups. Flea and mesostigmatan mite numbers and mesostigmatan mite species richness was significantly higher on reproductively active male than female rodents. Only ticks were significantly associated with habitat type, with significantly higher tick numbers and more tick species on rodents in the natural compared to the agricultural habitat. We conclude that the level of infestation by ectoparasites closely associated with the host (fleas and mites) was affected by host-associated factors, while infestation by ectoparasite that spend most of their life in the external environment (ticks) was affected by habitat type.
