据史料记载,每次鼠疫大流行,小型啮出类均参与流行。小型啮齿类生活习性与黄鼠有所不同,尤其是黑线仓鼠(Cricetulus barabehsis),它是一种家、野两栖的小型啮齿类,天气温暖转向野外,反之则转回居民区。所以,这种鼠在动物鼠疫流行时往往都参与流行。另外,它的繁殖力也非常强,四季均可繁殖,一年数窝。其它小型啮齿类也是如比。因此,研究小型啮齿动物的数量变动和寄生蚤对研究动物鼠疫流行具有重要意义。 According to historical records, each plague pandemic, small out of class are involved in the popular. Small rodents are different from the gopher in their habits of life, especially the Cricetulus barabehsis, a small, rodent amphibian that turns warm to the wild and vice versa. Therefore, these rats are often involved in the epidemic of animal plague. In addition, its fertility is also very strong, all seasons can be breeding, a nest a year. Other small rodents are also comparable. Therefore, the study of the small number of rodents and parasitic fleas changes in the study of animal epidemics is of great significance.
