China and the World Health Organization have defined five major parasites. Five major parasites in China: Plasmodium, Schistosoma, Hookworm, Filariasis, Leishmania donovani. The five major parasites of the World Health Organization: Plasmodium, Schistosoma, Filariasis, Leishmania donovani, Trypanosoma.

Parasite

Trypanosoma Protozoan phylum. There are many types of trypanosomes, which are parasitized in the blood and tissue fluids of various vertebrates (fish, amphibians, reptiles, birds, and mammals). Some species, such as Trypanosoma solani, are parasitic in human cells. Except for Trypanosoma rubens, which is transmitted directly through copulation, all trypanosomes that are parasitic to vertebrates rely on certain insects (such as tsetse fly) for transmission. After the blood of the vertebrate with trypanosomes is sucked up by the vector animals, due to the changes in the living environment of the trypanosomes, the digestive tract of the vector animals passes through the flagellar body or the flagellar body of the pre-flagellate body and the posterior-circular cone-flagellate body in order. . Only such post-circulating trypanosomes are infectious to the host in vector animals. When the vector bites the host again, the post-cycle trypanosomes are introduced into the host. Trypanosoma esculenta does not undergo any development in the digestive tract of the vector. It relies on the mechanical transmission of the vector within a short time after the blood is sucked. Trypanosoma mainly obtains nutrition from the host through puffing. All trypanosomes can be continuously cultured in vitro.
