The effect of anti-mosquito-midgut antibodies on the development of the malaria parasite, P. vivax was studied by feeding the vector mosquito, An. culicifacies with infected blood supplemented with serum from immunized rabbits. In order to get antisera, rabbits were immunized with midgut proteins of three siblings species of Anopheles culicifacies, reported to exhibit differential vectorial capacity. The mosquitoes that ingested anti-midgut antibodies along with infectious parasites had significantly fewer oocysts compared to the control group of mosquitoes. The immunized rabbits generated high titer of antibodies. Their cross reactivity amongst various tissues of the same species and with other sibling species was also determined. Immunogenic polypeptides expressed in the midgut of glucose or blood fed An. culicifacies sibling species were identified by Western blotting. One immunogenic polypeptide of 62 kDa was exclusively present in the midgut of species A. Similarly, three polypeptides of 97, 94 and 58 kDa and one polypeptide of 23 kDa were present exclusively in species B and C respectively. Immunoelectron microscopy revealed the localization of these antigens on baso-lateral membrane and microvilli. The effects of anti-mosquito midgut antibodies on fecundity, longevity, mortality and engorgement of mosquitoes were studied. Fecundity was also reduced significantly. These observations open an avenue for research toward the development of a vector-based malaria parasite transmission-blocking vaccine.
