Presence of Antibody to a Heterologous Circumsporozoite Protein of Plasmodiumvivax (VK247) in South-Eastern Bangladesh

摘要

Sera from 228 inhabitants of a malaria endemic region of south-eastern Bangladeshwere tested for antibodies to the circumsporozoite proteins of Plasmodium falciparum (R32tet32), P. vivax (NS1V20), and a polymorph of P. vivaxVK247). more than 50% were Ab positive, including 24% of the total for the polymorph. This finding proves that the polymorph exists in malarious foci in all the contiguous countries of India, Bangladesh, Burma, Thailand and Cambodia.
