There are 5 species of nematodes of the family Filarioidea responsible for disease in man.

ORGANISM VECTOR

  • Wuchereria bancrofti - mosquito: Culex, Aedes, Anopheles
  • Brugia malayi - mosquito
  • Brudia timori - mosquito
  • Loa loa - deerfly: Chrysops
  • Onchocerca volvulus - blackfly: Simulium

These nematodes require two hosts to complete their life cycle, and following infection and development of the adult worm in a human host, the female worm releases larval microfilariae. These are then spread by insect vectors.
