The genetics of human susceptibility to lymphatic filariasis, the genetic basis of filarial susceptibility in vector mosquitos, and the genetic constitution of human filarial parasites and their mosquito vectors are reviewed. It is evident that our present knowledge on the genetics of lymphatic filariasis is still very meagre. The need to study various genetic aspects of the disease is highlighted.
Laboratory strain of the Malaysian Culex quinquefasciatus was susceptible to Wuchereria bancrofti. Thirty three percent of the Cx. quinquefasciatus that fed on W. bancrofti patient were infective after 12-14 days. There is a possibility for W. bancrofti to occur in the urban areas of the Malaysia in the near future.
