High-throughput neutralization assay for multiple flaviviruses based on single-round infectious particles using dengue virus type 1 reporter replicon.

ABSTRACT: Diseases caused by the genus Flavivirus, including dengue virus (DENV) and Zika virus (ZIKV), have a serious impact on public health worldwide. Due to serological cross-reactivity among flaviviruses, current enzyme-linked immunosorbent assay (ELISA) for IgM/G cannot reliably distinguish between infection by different flaviviruses. In this study, we developed a reporter-based neutralization assay using single-round infectious particles (SRIPs) derived from representative flaviviruses. SRIPs were generated by transfection of human embryonic kidney 293 T cells with a plasmid encoding premembrane and envelope (prME) proteins from DENV1-4, ZIKV, Japanese encephalitis virus, West Nile virus, yellow fever virus, Usutu virus, and tick-borne encephalitis virus, along with a plasmid carrying DENV1 r
