Detection of P.falciparum and P.vivax sporozoites in mosquitoes by ELISA

ABSTRACT

A total of 10.140 Anopheles mosquitoes were collected during the period 1985-1995 in 5 study sites. ELISA(+) reactions were detected in 229 mosquito samples from 10 Anopheles species of An.minimus, An.dirus, An.vagns, An.maculatus, An.subpictus, An.campestris, An.tessellatus, An.jeyporiensis, An.aconitus, An.spl. In Bai Tranh (Thanh Hoa province), Khanh Phu and Khanh Nam (Khanh Hoa province), 7 species were found to be infected with malaria sporozoites as An.minimus, An.dirus, An.vagus, An.maculatus. An.aconitus, An.tessellatus, An.jeyporiensis. In the brackish water commune Phong Phu (Binh Chanh district, HCM city) and in Can Giuoc district (Long An province), 7 species were found to be infected with malaria sporozoites as An. subpictus, An.sinensis, An.sundaicus, An.campestris, An.vagus, An.tessellatuss, An.spl. The positive infection rate was An.dirus (4,5% - 8,5%), An.minimus (8,3%) in Khanh Phu and Khanh Nam (Khánh Hòa) and An.sinensis (4,5% - 11%). An.campestris (6,6% - 6,7%), An.vagus (4,6%) in Phong Phu (HCM city) and Can Giuoc (Long An)
