寄生虫与宿主的相互作用

通过对寄生虫与宿主的相互关系及影响因素进行研究,以有效地控制寄生虫病的发生.结果:不同种类的寄生虫具有不同的亲和性,可在机体的不同脏器或组织寄生.当有两种或两种以上的寄生虫感染时,它们通过相互协同或相互拮抗,共同参与寄生虫抗宿主反应,引起机械性损伤、营养不良、变态反应等.同时,机体对入侵的寄生虫产生一系列免疫反应,及时清除入侵的寄生虫,并具有抵抗再感染的能力,或形成免疫耐受.

The proceeding study on the relationship between parasites and host

Through the study on the relationship between the parasites and the host and their effective factors,the authors find that,different kinds of parasites have different affinity and can parasitize in different organs and tissues of host. In the period of infection caused by two or more than two kinds of parasite, the parasite versus host reaction (PVHR),mechanical trauma, malnutrition allergic reaction etc. will emerge with the interaction of the above parasites. On the other hand, in order to eliminate invasive parasite and establish immunity to parasite, a series of immune reaction appear in the host.
