The endoparasite fauna of the spiny mouse (Acomys spinosissimus) was studied for the first time from April 2007 until April 2009 in a population from the Limpopo Province of South Africa. In a total of 129 mice examined, only 6 endoparasite taxa were found, 2 nematode species (Syphacia minuta, Monanema joopi), 1 genus of cestodes ( Rodentolepis spp.), and unidentified hymenolepidid fragments. In addition, 1 pentastomid species (Armillifer grandis) as well as unidentified porocephalid specimens were recovered. The overall prevalence was low, at 15.5%, and only 1 individual harbored more than 1 parasite species. With 12.4% prevalence, S. minuta was the most prevalent parasite. Its prevalence and abundance were significantly higher during the dry and cooler season than during the wet and warm season, while a female-biased burden was observed during the wet season only. For the remaining parasite species, low prevalence prevented meaningful statistical analyses. The observed parasite species richness, prevalence, and abundance for A. spinosissimus were low compared to values reported for other Acomys spp. This may be linked to the lack of anthropogenic influences in the study population as well as the small size of A. spinosissimus .
2007年4月至2009年4月,首次对南非林波波省一个种群的刺毛鼠(Acomys spinosissimus)体内寄生虫区系进行了研究。在总共检查的129只小鼠中,仅发现6种体内寄生虫分类群,2种线虫(微小管状线虫、约氏莫南线虫)、1个绦虫属(啮齿类绦虫属)以及未鉴定的膜壳绦虫片段。此外,还发现了1种五口虫(巨型有沟绦虫)以及未鉴定的头槽绦虫标本。总体感染率较低,为15.5%,只有1只个体体内寄生有不止1种寄生虫。微小管状线虫感染率为12.4%,是最常见的寄生虫。其感染率和丰度在干燥凉爽季节显著高于湿润温暖季节,而仅在湿润季节观察到雌性感染负担偏重。对于其余寄生虫种类,由于感染率较低,无法进行有意义的统计分析。与其他刺毛鼠属物种报告的值相比,刺毛鼠观察到的寄生虫物种丰富度、感染率和丰度较低。这可能与研究种群缺乏人为影响以及刺毛鼠体型较小有关。
