Research Abstract

The aim of the malaria transmission-blocking vaccine(TBV) is to block the development of malaria parasites in the mosquito and prevent the following infection to the host. We focused on the Pvs230 as a candidate molecule, and produced recombinant Pvs230 protein using cell-free system. Rabbit antisera against the rPvs230 reacted on the surface of P. vivax gametocytes taken from Thai patients. The antisera reduced the infectivity of P. vivax parasites to Anopheles dirus mosquitoes by membrane feeding assay.
