Abstract
Lymphatic filariasis caused by the lymph-dwelling filarial parasites infects over 120 million people. While the majority of the infections are subclinical, ~40 million have lymphedema and/or other pathological manifestations ranging from episodic adenolymphangitis, hydroceles, lymphedema, or elephantiasis. The adult worms residing in the lymphatics induce lymphatic dilatation rendering them dysfunctional. Progression to lymphedema and elephantiasis is mediated primarily from the host inflammatory responses to the parasite and perhaps to the Wolbachia endosymbiont or as a consequence of superimposed secondary bacterial and fungal infections.
