The ectoparasitic acarines of commensal and wild rodents collected from various areas in Riyadh Region were four species of mites (Laelaps nutalli, Ornythonyssus bacoti, Cheyletus eruditus and Articholaelaps glasgowi), and two species of ticks. (Immature stages) Rhipicephalus spp. and Hyalomma spp. In urban areas the highest infestation rate by mites was 49.9% on Rattus rattus followed by 18.5% on Rattus norvegicus. The highest rat-mite index was 2.3 on R. rattus followed by 1.3 on R. norvegicus and 0.1 on Mus musculus. In semiarid areas, the highest rat-mite index was 2.1 on Gerbillus spp. followed by 1.7 on Meriones spp., 1.6 on Jaculus jaculus and 0.9 on Acomys dimidiatus. The highest infestation rate by mites was on Meriones spp. followed by Gerbillus spp. and then A. dimidiatus.
从利雅得地区不同区域收集的共生和野生啮齿动物的体外寄生螨类有4种螨（纳氏厉螨、柏氏禽刺螨、普通肉食螨和格拉斯哥阿氏厉螨）以及2种蜱（未成熟阶段），即扇头蜱属和璃眼蜱属。在城市地区，螨类感染率最高的是黑家鼠，为49.9%，其次是褐家鼠，为18.5%。最高的鼠螨指数在黑家鼠上为2.3，其次在褐家鼠上为1.3，在小家鼠上为0.1。在半干旱地区，最高的鼠螨指数在沙鼠属上为2.1，其次在长爪沙鼠属上为1.7，在五趾跳鼠上为1.6，在荒漠刺鼠上为0.9。螨类感染率最高的是长爪沙鼠属，其次是沙鼠属，然后是荒漠刺鼠。
