Using paired sera, HI serology gave 60.7% positive results. IgG ELISA antibodies showed cross reaction between dengue and JE, and also not so efficient to detect significant antibody rise. By IgM capture ELISA 60.5% positive results was obtained using acute sera and dengue 4 antigen alone for diagnosis. When paired sera and all 4 types of dengue were used, 82.1% positive results were obtained by the IgM-capture ELISA, and none of the test sera had diagnostic levels of IgM-ELISA antibodies against JE. The results showed that IgM capture ELISA is a useful method for rapid diagnosis of dengue infections and has advantages over HI in terms of its diagnostic efficiency even by a single serum specimen, rapidity, simplicity and differential diagnosis with other related flavivirus infections like JE., 熱帯医学 Tropical medicine 27(1). p23-36, 1985}, pages = {23--36}, title = {ビルマ,ラングーンにおけるデング出血熱患者血清中のデングおよび日本脳炎抗体価}, volume = {27}, year = {1985} }
