Each of the following parasite is transmitted by mosquito except :

  • A.Leishmania donovi
  • B.Wuchereria bancrofti
  • C.Plasmodium vivax
  • D.Plasmodium falciparum

Answer: A

The parasite not transmitted by mosquitoes is Leishmania donovani (printed 'donovi').

Leishmania donovani, the cause of kala-azar (visceral leishmaniasis), is transmitted by the bite of sandflies of the genus Phlebotomus, not by mosquitoes.

The others are all mosquito-borne. Wuchereria bancrofti, which causes lymphatic filariasis, is spread mainly by Culex mosquitoes, and Plasmodium vivax and P. falciparum, which cause malaria, by female Anopheles mosquitoes.
