flavivirus

The arboviral serology report on 17 November indicated evidence of infection with a flavivirus, according to neutralizing antibody testing, with a plaque reduction neutralization test (PRNT) titer > 1 280 for ZIKV (positive control titer > 320).

El ZIKV pertenece a la familia Flaviviridae, genero Flavivirus, al cual tambien pertenecen varios otros virus transmitidos por vectores relevantes para la salud humana, como el virus del dengue (DENV), el virus de la fiebre amarilla (YFV), el virus de la encefalitis japonesa (JEV), el virus del Nilo Occidental (VNO) y el virus de la encefalitis transmitida por garrapatas (TBEV).

Viruses in the genus Flavivirus have an RNA genome approximately 11 kb of RNA in length.

Persons with negative results for Zika virus by RT-PCR in all specimens tested are considered to have presumptive recent infection with a single arbovirus when results are positive for that virus by IgM ELISA, and presumptive flavivirus infection if they test positive for both Zika virus and dengue virus by IgM ELISA.

Flavivirus serology is complex, due to extensive cross-reactivity between antibodies made in response to different flavivirus infections or vaccination.

If the Zika virus test is either positive or equivocal, then the woman has a presumptive recent Zika virus or Flavivirus infection, regardless of the dengue virus IgM result.

6) Electron microscopy findings suggested flavivirus replication in brain tissue.

West Nile virus (WNV), a flavivirus, (1) is generally arthropod-borne and is currently the most common cause of epidemic meningo-encephalitis in North America.

Covering molecular virology and virus prevention, the anthology could serve as a reference for experienced flavivirus researchers or a threshold for newcomers.

WVN is a positive sense single-stranded RNA enveloped virus of the genus Flavivirus, family Flaviviridae.

Other contributions report findings on eastern equine encephalitis virus genomes, the lyssavirus genome, correlations of phylogenetic relation among members of the genus Flavivirus, and the construction of an infectious molecular clone of HTLV-1.

According to MOH National Campaign for the prevention of AlKhumra Hemorrhagic Fever, the virus (genus Flavivirus, AHFV) was recently identified as the agent of a viral hemorrhagic fever in Saudi Arabia and characterized serologically and genetically as a variant genotype of Kyasanur Forest disease virus (KFDV).

Objetivo Los miembros del genero Flavivirus poseen epitopes inductores de anticuerpos de reactividad cruzada, lo que representa una gran dificultad en el diagnostico diferencial.

El estudio demostro la complejidad del serodiagnostico de Flavivirus en las zonas endemicas como la del Caribe colombiano.

The findings provide the first detailed view of a flavivirus and offer structural information that can be used to unravel the processes that lead to viral infection.
