Lymphatic filariasis is a human disease caused by parasitic worms known as filarial worms. [2] [3] Usually acquired in childhood, it is a leading cause of permanent disability worldwide, impacting over a hundred million people and manifesting itself in a variety of severe clinical pathologies [6] [7] While most cases have no symptoms, some people develop a syndrome called elephantiasis, which ...
Lymphatic filariasis is caused by the worms Wuchereria bancrofti, Brugia malayi, and Brugia timori. These worms occupy the lymphatic system, including the lymph nodes; in chronic cases, these worms can lead to the syndrome of elephantiasis. Loiasis a subcutaneous filariasis is caused by Loa loa (the eye worm).
Wuchereria bancrofti is a filarial (arthropod-borne) nematode (roundworm) that is the major cause of lymphatic filariasis. It is one of the three parasitic worms, together with Brugia malayi and B. timori, that infect the lymphatic system to cause lymphatic filariasis. These filarial worms are spread by a variety of mosquito vector species.
Brugia malayi is a filarial (arthropod-borne) nematode (roundworm), one of the three causative agents of lymphatic filariasis in humans. Lymphatic filariasis, also known as elephantiasis, is a condition characterized by swelling of the lower limbs. The two other filarial causes of lymphatic filariasis are Wuchereria bancrofti and Brugia timori ...
Elephantiasis tropica (known as lymphatic filariasis), caused by a number of parasitic worms, particularly Wuchereria bancrofti. More than 120 million people, mostly in Africa and Southeast Asia, are affected. [3] Nonfilarial elephantiasis (or podoconiosis), an immune disease affecting the lymph vessels [citation needed] Leishmaniasis [2]
Whole blood with microfilaria worm, from a person with Loa loa, Giemsa stain. The mature worms live in the body fluids and cavities of the definitive hosts, or predominantly in particular tissues. Details vary according to species. Some of the worst pathogens invade lymphatic vessels and may be numerous enough to clog them.
Using education and simple, low-cost methods, the Carter Center’s health initiatives addressed “neglected tropical diseases”: lymphatic filariasis, trachoma, schistosomiasis and malaria.
The Global Programme to Eliminate Lymphatic Filariasis (GPELF) is a World Health Organization project to eradicate the Filarioidea worms which cause the disease lymphatic filariasis and also treat the people who already have the infection.
