Filariasis, is a filarial infection caused by parasitic nematodes (roundworms) spread by different vectors.They are included in the list of neglected tropical diseases.. The most common type is lymphatic filariasis caused by three species of Filaria that are spread by mosquitoes.
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 ...
Various filarial diseases specific to humans are candidates for elimination by such means as breaking the cycle of infection. To eliminate the vectors is not really practical, but if the human population were sufficiently cleared of parasites by treatment with filaricides then one year without any human reservoirs of infection should suffice to ...
Loa loa life cycle. Source: CDC. During a blood meal, an infected Chrysops fly introduces third-stage filarial larvae onto the skin of the human host, where they penetrate into the bite wound. The larvae develop into adults that commonly reside in subcutaneous tissue. The female worms measure 40 to 70 mm in length and 0.5 mm in diameter, while ...
Mebendazole, another possible treatment for M. perstans filariasis, has been shown to be effective in significantly reducing microfilariae levels. It has been more effective than both ivermectin and DEC—with a greater number of responders, a more significant reduction in microfilariae levels, and the ability to eliminate the infection more ...
Like other human filariasis infections, Brugia timori filariasis causes acute fever and chronic lymphedema. The life cycle of Brugia timori is very similar to that of Wuchereria bancrofti and Brugia malayi, leading to nocturnal periodicity of the disease symptoms. Eosinophilia is common during acute stages of infection.

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.
