Plasmodium sporozoites collected from oocysts, haemocoel and salivary glands of the mosquito show profound differences in their biological properties such as motility, ability to induce protective immune response and infectivity for vertebrate host cells. Sporozoites from salivary glands are much more infectious than those from oocysts and haemocoel.(More)
Immunization with irradiated sporozoites can protect against malaria infection and intensive efforts are aimed at reproducing this effect with subunit vaccines. A particular sequence of subunit immunization with pre-erythrocytic antigens of Plasmodium berghei, consisting of single dose priming with plasmid DNA followed by a single boost with a recombinant(More)
Serine proteases are among the enzymes that play a crucial role during the digestion of the blood meal in the gut of mosquitoes. The identification of the corresponding genes would have important implications for the control of mosquitoes and mosquito-borne diseases. Analysis of the genomic organization of these genes may lead to the isolation of a(More)
Malaria transmission blocking (TB) vaccines (TBVs) directed against proteins expressed on the sexual stages of Plasmodium parasites are a potentially effective means to reduce transmission. Antibodies induced by TBVs block parasite development in the mosquito, and thus inhibit transmission to further human hosts. The ookinete surface protein P25 is a(More)
