摘　　要：鼠疫是一种自然疫源性疾病。在它的3个要素中,人们往往更偏重于研究鼠疫菌和宿主之间的关系,而忽视了传播媒介的重要作用。然而,实际上蚤在动物鼠疫的流行和保存过程中起着非常重要的作用。作者通过文献积累,列举了蚤与鼠疫菌之间的4种生物学关系而得出结论:蚤与鼠疫菌之间的生物学关系绝非一般的生物学概念上的寄生关系。在动物鼠疫流行过程中,这种关系的动态平衡是起决定性作用的。The plague is a kind of natural epidemic disease. In its three fac tors, the people often lay particular stress on studying the relations between Y . pestis and host animals and ignore important roles of spreading medium, howeve r, it has important roles for fleas to keep plague epizootic on epidemiology. Au thor has enumerated four kinds of biological relationships between fleas and Y. pestis by accumulating documents and come to conclusions that biological relatio ns between fleas and Y. pestis aren't ordinary parasitic ones on biology concep ts and its dynamic equilibrium has a desive role in the process of prevalanting plague epizootic.
