摘要

啮齿动物传播的疾病,如黑死病,仍然是热带国家公共卫生的重大威胁。在鼠疫流行地区,关于引发周期性暴发的因素的信息很少,因此难以制定预防致命人畜共患病负面影响的防范战略。在这项研究中,我们评估了坦桑尼亚Mbulu地区啮齿动物的物种丰富度、多样性和群落结构与鼠疫持续存在的关系。采用灭鼠夹法采集鼠类资料。共捕获鼠类12种610只,以Mastomys natalensis数量最多。鼠疫持续地的种群丰度和物种丰富度显著高于非持续地。此外,房屋生境的物种丰富度明显低于农场和森林生境。此外,我们发现三种广泛的啮齿动物群落结构在研究的栖息地类型之间存在显著差异,表明在精细尺度的资源丰度下,啮齿动物种群之间存在高度的相互作用。鼠疫易感鼠宿主的高丰度和多样性可能是鼠疫在疫源地持续存在的原因。这些结果可能有助于在这些地区制定预防战略以控制鼠疫暴发。

Rodent abundance, diversity and community structure in a bubonic plague endemic area, northern Tanzania
Abstract Rodent-borne diseases such as bubonic plague remain a significant threat to public health in tropical countries. In plague-endemic areas, little information exists on the factors triggering periodic bursts, thus rendering preparedness strategies for preventing the negative impacts of the deadly zoonosis difficult. In this study, we assessed how species richness, diversity, and community structure of rodents are associated with plague persistence in Mbulu District, Tanzania. Rodent data were collected using the removal trapping technique. We captured 610 rodents belonging to 12 species, with Mastomys natalensis recording highest abundance. There was significantly higher abundance and species richness in persistent than non-persistent plague locality. Also, house premises recorded significantly lower species richness than farm and forest habitats. Additionally, we found three broad rodent community structures that varied significantly between studied habitat types suggesting high rodent populations interaction at fine-scale resource abundance. The high abundance and diversity of plague-susceptible rodent reservoirs suggestively contribute to the plague persistence in the foci. These results may be useful to developing preparedness strategies in these areas to control plague outbreaks.

期刊介绍: Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
