Development of real-time reverse transcriptase PCR assays to detect and serotype dengue viruses.

ABSTRACT: Serotyping dengue virus (DENV) from suspect human specimens is crucial for developing sound epidemiological control measurements early in the transmission season and for effective patient management. We modified DENV consensus D1 (mD1) and serotype-specific TS2 (mTS2) and redesigned serotype-specific TS1 (rTS1) and TS4 (rTS4) as described previously in the conventional capsid and premembrane gene (C-prM) protocol (R. S. Lanciotti, C. H. Calisher, D. J. Gubler, G.-J. Chang, A. V. Vorndam, J. Clin. Microbiol. 30:545-551, 1992). In addition, we designed two new sets of amplimers and probes, located at nonstructural protein 5 (NS5) and the 3' noncoding region (3'NC) of DENV. The NS5 protocol utilizes two flaviviral consensus outer amplimers (mFU1 and CFD2) and four dengue virus serotype-specif
