丝虫病系指丝虫目寄生线虫通称丝虫引起人类和动物传染病的总称。这个目包括3个科97属537种,其中寄生于哺乳类39属229种、鸟类43属255种、爬行类12属30种及两栖类3属23种。这些丝虫成虫寄生脊椎动物的管腔、组织与体腔,雌虫产出胚胎称微丝蚴,幼虫在特定吸血节肢动物体内发育,如蚊、虹、蚋、蠓、蚤、蜱与螨。寄生人体丝虫主要8种,全属盖头科,按其成虫生态可将本病分为3组,见表1、2。与我国人体有关者仅其中吴策属和布鲁属丝虫,现将其分类宿主和分布问题研究进展分述如下。
Filariasis is a general term for filarial worms that cause parasitic diseases in humans and animals. This subfamily includes 537 species of 97 genera in 3 families, of which 229 species belong to 39 genera and mammals, 255 species belong to 43 genera, 30 species belong to 12 genera and 23 species belong to 3 genera of amphibians. These filamentous adults parasitize the lumens, tissues and body cavities of vertebrates. The female produces embryos called microfilariae. The larvae develop in certain blood-sucking arthropods, such as mosquitoes, sires, flies, fleas, ticks and mites. The main 8 parasitic filarial filariasis, all belong to the cover family Section, according to their adult ecology can be divided into three groups of the disease, see Table 1, And our body related only to Wu policy and Brucella filariasis, now its classification of hosts and distribution of research progress are described below.
