Serological differentiation of infections with dengue virus serotypes 1 to 4 by using recombinant antigens.
نویسندگان
چکیده
The B domains of dengue virus serotypes 1 to 4 were expressed in Escherichia coli. The purified proteins were applied to immunoblot strips to detect serotype-specific antibodies in paired serum samples from 41 patients with primary and secondary dengue infections. A close correlation between the results obtained with the immunoblot strips and by type-specific reverse transcription-PCR (T. Laue, P. Emmerich, and H. Schmitz, J. Clin. Microbiol. 37:2543-2547, 1999) was observed.

Recombinant Envelope-Proteins with Mutations in the Conserved Fusion Loop Allow Specific Serological Diagnosis of Dengue-Infections
Dengue virus (DENV) is a mosquito-borne flavivirus and a major international public health concern in many tropical and sub-tropical areas worldwide. DENV is divided into four major serotypes, and infection with one serotype leads to immunity against the same, but not the other serotypes. The specific diagnosis of DENV-infections via antibody-detection is problematic due to the high degree of c...
متن کاملVirological interpretations of dengue disease spectrum in infants in Chennai, Tamil Nadu, India, need reevaluation.
We read with interest the study of Kabilan et al. (2) regarding the dengue disease spectrum in infants in Chennai, Tamil Nadu, India. However, certain points in this study regarding the virological investigations and their interpretations are not clear. As specified in the paper, the authors used denguespecific immunoglobulin M (IgM) and IgG microenzymelinked immunosorbent assay (microELISA) re...
متن کاملImmunoglobulin M enzyme-linked immunosorbent assay using recombinant polypeptides for diagnosis of dengue.
We demonstrate that a mixture of four recombinant dengue virus E polypeptides corresponding to the N-terminal region of the envelope protein from all serotypes substitutes for standard antigens in two immunoglobulin M enzyme-linked immunosorbent assay formats with 100% concordance, making these polypeptides a useful and accessible reagent for serological diagnosis of dengue in endemic countries.

BACKGROUND AND PURPOSE We previously reported the development of a non-structural protein NS1 serotype-specific immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA) for dengue serodiagnosis and seroepidemiological study. This assay can be used to differentiate the immunologic status of individuals into naive, primary, or secondary dengue virus (DENV) infection and identify the DENV ...

Background: Dengue is a global arboviral threat to humans; causing 390 million infections per year. The availability of safe and effective tetravalent dengue vaccine is a global requirement to prevent epidemics, morbidity, and mortality associated with it. Methods: Five experimental groups (6 mice per group) each of 5-week-old BALB/c mice were immunized with vaccine and placebo (empty plasmid) ...
