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. [12]
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.
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).
Buckley reexamined all the Wuchereria species in 1960, and concluded that the genus should contain only W. bancrofti. He created a new genus Brugia in honour of the original discoverer, thus renaming B. malayi, B. pahangi, and B. patei. [10] In 1977, a new species B. timori was reported from Flores Island in Indonesia. [11]
Brugia malayi; Brugia timori; 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.
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]

Roundworms such as Brugia, Wuchereria and Onchocerca are directly transmitted by mosquitoes. [31] [32] In the developing world, the use of contaminated water is a major risk factor for infection. [33] Infection can also take place through the practice of geophagy, which is not uncommon in parts of sub-Saharan Africa. Soil is eaten, for example ...
