Serotype-Specific Detection of Dengue Viruses in a Fourplex Real-Time Reverse Transcriptase PCR Assay
TL;DR: This serotype-specific, fourplex real-time reverse transcriptase PCR nucleic acid detection assay can be used as a method for differential diagnosis of a specific DEN serotype in viremic dengue patients and as a tool for rapid identification and serotyping of DEN virus isolates.
Journal ArticleDOI
Laboratory Diagnosis of Chikungunya Virus Infections and Commercial Sources for Diagnostic Assays.
TL;DR: Nine commercial CHIKV IgM detection assays were evaluated at 3 reference laboratories to provide guidance to public health diagnostic laboratories on their performance parameters and showed comparable performance to reference assays.

Maria Morales-Betoulle,M. L. Monzón Pineda,Silvia M. Sosa,Nicholas A. Panella,Celia Cordon-Rosales,Nicholas Komar,Ann M. Powers,Barbara W. Johnson +7 more
TL;DR: Nucleotide sequence comparison of the eight flavivirus RNA-positive pools showed that there was 100% identity among them, and phylogenetic analysis of the NS5 and envelope gene regions indicated that they represent a strain of the recently described CxFV from Japan.
