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.
Examples are W. bancrofti, whose vector is a mosquito; night is the preferred time for blood collection. Loa loa's vector is the deer fly; daytime collection is preferred. [7] This method of diagnosis is only relevant to microfilariae that use the blood as transport from the lungs to the skin.
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 ...
Three species of filarial roundworms, all from the Onchocercidae family, cause human lymphatic filariasis: Wuchereria bancrofti, Brugia malayi, and Brugia timori. [1] Tropical pulmonary eosinophilia is a rare syndrome characterised by pulmonary interstitial infiltrates and marked peripheral eosinophilia. [2]
Wuchereria bancrofti [7] Three other medically important parasitic species are: Loa loa causes Loa loa filariasis also known as Calabar swelling; Mansonella streptocerca, which causes streptocerciasis, an itchy condition that creates depigmented skin lesions sometimes mistaken for the first signs of leprosy.
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]
Buckley proposed to divide the old genus Wuchereria, into two genera, Wuchereria and introduced a new Brugia after the original discoverer. Then Wuchereria contains only W. bancrofti, which so far has been found to infect only humans, and the genus Brugia contains B. malayi, which infects humans and animals, as well as other zoonotic species.

Chyluria is often caused by filariasis due to the parasite Wuchereria bancrofti, a thready nematode which lodges the lymph channels. [2] [5] The parasitic infection can lead to obstruction of peripheral lymphatic vessels and increased pressure within the vessels causing collateral flow of the lymph, redirecting the lymph flow from the intestinal lymphatic vessels into the lymphatic vessels of ...
