甘肃省鸟类与自然疫源性疾病

Birds in Gansu Province and Natural Focal Diseases

本文就鸟类与自然疫源性疾病关系作尝试性探讨。全省可作为有关自然疫源性疾病病原体宿主或携带者的脊推动物１３３种，其中鸟类３４种，占全省鸟类５６４种的５．３２％，占全省动物宿主总数的２５．５６％，仅次于啮齿动物宿主（３８．３５％）。鸟类可作为鼠疫等７种自然疫源性疾病宿主，是森林、森林草原和草原疾病的主要宿主，它染疫后通过飞行迁徙将病原体做远程转移，可能使疫区扩大或形成新的疫源地。因此鸟类具有重要的流行病学意义。然而甘肃对鸟类与自然疫源性疾病研究甚少。本文目的在于引起重视，加强研究。

This paper tries to discuss on relationship between birds and natural focal diseases。It had been demonstrated that l33 kinds of vertebrate are carriers or hosts to carry pathogens of natural focal diseases。Out of the vertebrates,34 species of birds are hosts with 5.32%of 564 kinds of birds and 25.56%of totai an-imal hosts in Gansu province,only less than the rodent hosts。 The birds, which are main hosts of diseases in forest and forest grassland or grassland,can carry seven natural focal diseases,such as plague and so on。They are able to spread pathogens by migration after infection,making new natural foci or enlarging the foci。Therefore,birds are very important in epidemiology。
