Resumo: Chikungunya virus (CHIKV) causes endemic or epidemic outbreaks of CHIKV fever, which is a mosquitoe- transmitted viral disease in Africa, India, South-East Asia, - recently Southern Europe. Currently, serological diagnostic tests such as hemagglutination inhibition test (HI test), in-house IgM capture enzyme-linked immunosorbent assays (ELISA), - indirect immunofluorescence test were used for diagnosis of chikungunya fever, which are based on whole virus antigens. CHIKV E1, - E2 envelope proteins for the CHIKV-specific serodiagnostic reagents for chikungunya fever were expressed in baculovirus expression system. The seroreactivity of recombinant CHIKV E1 - E2 envelope proteins were evaluated using sera panels of patients from Laboratoire Marcel Merieux by indirect IgM capture ELISA. The recombinant CHIKV E1 - E2 envelope protein showed sensitivity of 77.5% - 90%, respectively. The specificities of both CHIKV E1 - E2 envelope proteins were 100%. The recombinant CHIKV E1 - E2 envelope proteins could be a useful diagnostic reagent for CHIKV infection.
