Eighty nine rats, Arvicanthis niloticus, were collected from the horticultural fields of Shendi area in Sudan, between January and June 2018, and examined for the first time for helminth parasites. Thirty seven (41.6%) of the collected rats were infected, with an overall mean intensity of 4.4 helminths per a rat. A total of 6 helminth species were identified including three nematodes (Nippostrongylus brasiliensis, Monanema nilotica and Capillaria hepatica) and three cestodes (Hymenolepis diminuta, H. nana and Taenia taeniae formis). The most prevalent helminth was found to be the nematode, N. brasiliensis (21.3%), followed by the cestode, H. diminuta (10.1%), while the least was the nematode, C. hepatica (1.1%). Higher prevalence and intensity of infection were observed among older rats. Likewise, male rats were found to harbor a higher prevalence and intensity of infection. In conclusion, the rat, A. niloticus in Shendi area has found to be parasitized by various species of helminths, which some are of zoonotic importance, thus, any possible contact between this rat and humans or their pets may pose potential risk to public health.
2018年1月至6月期间，从苏丹申迪地区的园艺场收集了89只尼罗多齿鼠，并首次对其进行蠕虫寄生虫检查。所收集的大鼠中有37只（41.6%）受到感染，每只大鼠体内蠕虫的总体平均感染强度为4.4条。共鉴定出6种蠕虫，包括3种线虫（巴西日圆线虫、尼罗莫南线虫和肝毛细线虫）和3种绦虫（微小膜壳绦虫、短膜壳绦虫和泡状带绦虫）。发现最常见的蠕虫是线虫巴西日圆线虫（21.3%），其次是绦虫微小膜壳绦虫（10.1%），而最少见的是线虫肝毛细线虫（1.1%）。在老年大鼠中观察到更高的感染率和感染强度。同样，发现雄性大鼠的感染率和感染强度更高。总之，已发现苏丹申迪地区的尼罗多齿鼠感染了多种蠕虫，其中一些具有人畜共患病重要性，因此，这种大鼠与人类或其宠物之间的任何可能接触都可能对公众健康构成潜在风险。
