It's an essay on Elephantiasis.

I did my report on filariasis, which is more commonly known as elephantiasis. Elephantiasis is the late phase of filariasis. Filariasis is a tropical mosquito born parasitic disease make obstruction of the lymph vessels. In some masses the presence of the worm causes a tissue reaction that causes the lymph strike to be blocked. This blockage produces lymphedema which is a swelling and can lastly lead to a tremendous enlargement of an extremity or organ. When elephantiasis follows repeated infection, parts of the physical structure -- particularly the legs -- become grossly enlarged and the surrounding skin hardens and ulcerates. Certain types of elephantiasis can be treated surgically. Elephantiasis of the legs is usually treated with elastic bandages and frequent face lift of the legs. The leg and foot, whitethorn swell to elephantine size. There may be allergic reactions like itching and localized swelling. The body may also react by causing calcium tissue to be deposited around the worm, walling it off and eventually causing its death. In humans, the mature worm lives tightly coiled in the lymphatic vessels where they reproduce. The female holds the fertilized eggs in her body. Later the embryos, called microfilariae, atomic number 18 discharged alive. An interesting feature of these worms is the periodic swarming of the microfilariae in the bloodstream. In most species swarming takes place at night.



The embryos can be interpreted up by an insect only when they are in a humans bloodstream. They develope into infective larvae in the insect, which is the intermediate host. These hosts are versatile genera of mosquitoes, notably A?des, Anopheles, and Culex. Within 10 to 11 old age after ingestion by a human skin they migrate to the lymphayic vessels where they mature and reproduce. There isnt really any streak to this disease.
