根据家畜疫源地理论,作为疫源地要素之一的媒介动物的研究包括研究(1)媒介动物和寄生物之间的矛盾,(2)媒介动物和外界环境之间的矛盾以及(3)媒介动物体内的寄生物和外界环境之间的矛盾。陕西省姜片吸虫病疫源地媒介动物的研究已在中间宿主的确定一文中,以及部分地在病原的研究一文中作过报导。这些报导都涉及到上述媒介动物和寄生物之间的矛盾范围内。关于上述(2)(3)的矛盾研究,将在本文内提出。这些都属于媒介动物扁卷螺生态学研究的性质。1962—1963年我们在陕西
According to animal foci theory, studies on vector animals that are one of the elements of foci include research on (1) contradictions between vector animals and parasites, (2) contradictions between vector animals and the external environment, and (3) The contradiction between the parasites in the animal body and the environment. Studies of vector animals in the endemic area of GISTs in Shaanxi Province have been reported in the Confirmation of Intermediate Hosts, and in part, in the article on pathogen research. These reports all deal with the contradictions between the aforementioned media animals and parasites. On the (2) (3) contradictory studies, will be presented in this article. All of these belong to the nature of the ecology of flat snails in vector animals. We were in Shaanxi from 1962 to 1963
