Some small mammals occur as household pests and harbour a number of parasites that could be of public health importance. This study profiled the helminth and protozoan parasites in trapped small mammals within and around human dwelling places (houses) located across 4 major towns (Auchi, Benin, Ekpoma, and Uromi) and environs in Edo state, Nigeria. Six genera ( sp., sp., , , sp., and sp.) were identified from 502 trapped small mammals. Overall, (71.9%) and (20.1%) were the most frequently trapped. In total, on examination of blood, gastrointestinal contents, and brain tissues, 12 helminth taxa ( sp., sp., sp., sp., sp., sp., and sp.), and 6 protozoan parasites ( sp., sp., sp., sp., and ) were isolated. Most prevalent helminths with relatively heavy mean intensity were sp. and , while , and were the most prevalent protozoan parasites. Generally, intrinsic factors like sex and age had marginal influence on the rate and burden of infection in and . Although the infection rate and prevalence of zoonotic parasites were low, they were largely recovered in rodents from Ekpoma. This study elucidates the public health implication of the presence of zoonotic parasites in these small mammals.
一些小型哺乳动物是家庭害虫,并携带许多可能对公共卫生具有重要意义的寄生虫。本研究对尼日利亚江户州4个主要城镇(奥奇、贝宁、埃克波马和乌鲁米)及其周边人类居住场所(房屋)内捕获的小型哺乳动物体内的蠕虫和原生动物寄生虫进行了分析。从502只捕获的小型哺乳动物中鉴定出6个属(种、种、种、种、种和种)。总体而言,(71.9%)和(20.1%)是最常捕获的。在对血液、胃肠道内容物和脑组织进行检查时,共分离出12种蠕虫类群(种、种、种、种、种、种和种)和6种原生动物寄生虫(种、种、种、种和)。平均强度相对较高的最常见蠕虫是种和,而种和是最常见的原生动物寄生虫。一般来说,性别和年龄等内在因素对和的感染率和感染负荷影响较小。尽管人畜共患寄生虫的感染率和患病率较低,但在来自埃克波马的啮齿动物中大多能检测到。本研究阐明了这些小型哺乳动物中存在人畜共患寄生虫对公共卫生的影响。
