The sydrome called 'elephantiasis' in which the arms and legs can grow to elephontoid size is caused by a roundworm true or false?

On September 20, 2007, scientists mapped the genome or genetic content of Brugia malayi, worm which cause elephantiasis (lymphatic filariasis).

Elephantiasis generally results from obstructions of the lymphatic vessels. It is most commonly caused by a parasitic disease known as lymphatic filariasis.

Alternatively, elephantiasis may occur in the absence of parasitic infection. This nonparasitic form of elephantiasis, known as nonfilarial elephantiasis or podoconiOSis, generally occurs in the mountains of central Africa. Nonfilarial elephantiasis is thought to be caused by persistent contact with volcanic ash
