In this report, the blood samples from 30 falciparum malaria patients with parasitemia 0.015-0.58% and the blood samples from 30 healthy persons were examined by monoclonal antibody (McAb) sandwich dot-immunogold silver staining assay (Dot-IGSSA). When the McAb 11G5, 13A2 and 13A1 were used for sandwich Dot-IGSSA with McAb 14D9 labeled with colloidal gold respectively, the 0.0001% of parasitemia could be detected and the McAb 11G5, 13A1 and 14D9 labeled with colloidal gold could also be used to detect the antigens of asexual blood stages of Yunnan and Anhui isolates of Plasmodium falciparum cultured in vitro. These McAbs did not cross-react with the antigens of Plasmodium knowlesi and Plasmodium berghei, however, the McAbs 13A1 and 14D9 weakly cross-reacted with the antigens of Plasmodium cynomolgi and the antigens in the infected blood samples from patients with vivax malaria.
