Mastomys natalensis 复合种为非洲野生啮齿动物的优势种群,它们在多种动物病的自然循环中发挥着重要的作用因而被人们用作研究疾病(例如:血吸虫病、回归热、Lassa 热、鼠疫)的实验动物。M.natalensis复合种还可再分成几个在形态学上一致而遗传学上各异的亚种,其中 M.natalensis 的染色体为二倍体,数目为2n=32,而 Mcouch的二倍体数为2n=36。对比研究证实这种近缘动物对鼠疫实验
The Mastomys natalensis complex is a dominant species of wild African rodents that play an important role in the natural circulation of many animal diseases and are therefore used by people to study diseases such as schistosomiasis, relapsing fever, Lassa fever, plague Experimental animals. The M. natalensis complex can also be subdivided into several morphologically identical and genetically diverse subspecies, in which the chromosome of M. natalensis is diploid with a number of 2n = 32, whereas the number of diploids of Mcouch 2n = 36. Comparative studies confirm the plague experiments of this kind of relatives
