DETECTING EPIDEMIC HEMORRHAGIC FEVER VIRUS ANTIGEN AND ANTIBODY BY IMMUNE ADHERENCE HEMAGGLUTINATION(IAHA) TEST
Abstract: We have modified and improved the method of immune adherence hemagglutination (IAHA) test and used it to detect virus antigen and antibody of epidemic hemorrhagic fever (EHF). We compared the IAHA titers of different strains infected in Vero-E_6 cells The IAHA titer of A_9 strain showed to be the highest (1: 64) among the three strains. 9 EHF patients paired sera, 3 con valecant sera and 6 immunized rabbits sera were detected with IAHA and compared with IFA. The positive rates detected by the two tests we...
