Why does Brugia malayi cause lymphatic filariasis?
• B. Malayi is one of the causative agents of lymphatic filariasis, a condition marked by infection and swelling of the lymphatic system. • The disease is primarily caused by the presence of worms in the lymphatic vessels and the resulting host response.
