Generation of a Reassortant Influenza A Subtype H3N2 Virus Expressing Gaussia Luciferase [PDF]

Viruses, 2019
Reporter influenza A viruses (IAVs) carrying fluorescent or luminescent genes provide a powerful tool for both basic and translational research. Most reporter IAVs are based on the backbone of either subtype H1N1 viruses, A/Puerto Rico/8/1934 (PR8) or A ...

Antigenic drift and subtype interference shape A(H3N2) epidemic dynamics in the United States [PDF]

eLife, 2023
Influenza viruses continually evolve new antigenic variants, through mutations in epitopes of their major surface proteins, hemagglutinin (HA) and neuraminidase (NA). Antigenic drift potentiates the reinfection of previously infected individuals, but the

Meta-Analysis of Seroprevalence and Prevalence of Influenza A Viruses (Subtypes H3N2, H3N8, and H1N1) in Dogs

Animals
Influenza A is a zoonotic disease that affects dogs, pigs, horses, poultry, and birds. In this report, a meta-analysis according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) was conducted.

Higher titers of some H5N1 and recent human H1N1 and H3N2 influenza viruses in Mv1 Lu vs. MDCK cells [PDF]

Virology Journal, 2011
Background The infectivity of influenza A viruses can differ among the various primary cells and continuous cell lines used for such measurements. Over many years, we observed that all things equal, the cytopathic effects caused by influenza A subtype ...

The evolutionary footprint of influenza A subtype H3N2 strains in Bangladesh: implication of vaccine strain selection

Scientific Reports, 2022
In February each year, World Health Organization (WHO) recommends candidate vaccine viruses for the forthcoming northern hemisphere (NH) season; however, the influenza season in the temperate zone of NH begins in October.

Seroepidemiological Evidence of Subtype H3N8 Influenza Virus Infection among Pet Dogs in China.

PLoS ONE, 2016
The H3N8 virus and the H3N2 virus are the main subtypes of canine influenza virus (CIV). H3N8 CIV mainly circulates in America, and H3N2 CIV mainly circulates in Asia.

Intensity and drivers of subtypes interference between seasonal influenza viruses in mainland China: A modeling study

iScience
Summary: Subtype interference has a significant impact on the epidemiological patterns of seasonal influenza viruses (SIVs). We used attributable risk percent [the absolute value of the ratio of the effective reproduction number (Rₑ) of different ...

Identification of combinatorial host-specific signatures with a potential to affect host adaptation in influenza A H1N1 and H3N2 subtypes [PDF]

BMC Genomics, 2016
The underlying strategies used by influenza A viruses (IAVs) to adapt to new hosts while crossing the species barrier are complex and yet to be understood completely. Several studies have been published identifying singular genomic signatures that indicate such a host switch.

Verification of the Combimatrix influenza detection assay for the detection of influenza A subtype during the 2007–2008 influenza season in Toronto, Canada [PDF]

Virology Journal, 2009
The increase in adamantine resistance in influenza A (H3N2) and the emergence of oseltamivir resistance in influenza A (H1N1) has necessitated the use of rapid methodologies to detect influenza subtype.

Molecular identification of neuraminidase gene mutations in influenza A/H1N1 and A/H3N2 isolates of Mazandaran province, north of Iran

Journal of Global Antimicrobial Resistance
Objectives: The neuraminidase (NA) mutations causing resistance to NA inhibitors (NAIs) mostly compromise the fitness of influenza viruses. Considering the importance of these mutations, constant monitoring of the effectiveness of available drugs is ...
