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 ...

Moderate Vaccine Effectiveness against Severe Acute Respiratory Infection Caused by A(H1N1)pdm09 Influenza Virus and No Effectiveness against A(H3N2) Influenza Virus in the 2018/2019 Season in Italy [PDF]

Vaccines, 2020
Every season, circulating influenza viruses change; therefore, vaccines must be reformulated each year. We aimed to estimate vaccine effectiveness (VE) against severe influenza infection for the 2018/19 season in Italy.

Swine-to-Human Transmission of Influenza A(H3N2) Virus at Agricultural Fairs, Ohio, USA, 2012

Emerging Infectious Diseases, 2014
Agricultural fairs provide an opportunity for bidirectional transmission of influenza A viruses. We sought to determine influenza A virus activity among swine at fairs in the United States.

Development of DNA-Biochip for Identification of Influenza A Virus Subtypes [PDF]

Проблемы особо опасных инфекций, 2012
Developed was the DNA-biochip to identify subtypes of influenza A virus, pathogenic for humans. Microchip was capable of detecting H1, H3, H5-subtypes of hemagglutinin (including H1-subtype of pandemic A/H1N1(2009) influenza virus ) and neuraminidase ...

Development of the cell-ELISA test for the subtype identification of circulating influenza A(H1) and A(H3) viruses [PDF]

Microbiology Independent Research Journal, 2015
The sensitive version of cell-ELISA was developed for the subtype-specific differentiation of current influenza A(H1N1)pdm09 and A(H3N2) viruses that are circulating in the human population. This method is based on the estimation of virus reproduction in

Recurring Temporal Association Between Influenza A Epidemics and Subsequent Influenza B Dominance in Post-Pandemic Korea, 2022-2026. [PDF]

J Med Virol
ABSTRACT Post‐pandemic influenza dynamics have shown unusual patterns globally. We investigated the re‐emergence and recurrent seasonal dominance of influenza B in Korea across three post‐pandemic seasons (2022−2026). We analyzed 157 consecutive weeks of national sentinel surveillance data (K‐SenS, Korea Disease Control and Prevention Agency), covering

Emergence and Evolution of Novel Canine-Avian Reassortant H3N2 Influenza A Viruses in Duck in Leizhou Peninsula, China

Frontiers in Microbiology, 2022
Avian-to-mammal transmission and mammalian adaptation of avian influenza virus (AIV) are threats to public health and of great concern. The H3 subtype of influenza virus has low pathogenicity and is widely distributed in humans, canines, equines and ...

Genomic and Clinical Analysis of Influenza A in Hospitalized Adults, 2019-2024: Exploratory Evidence on Neuraminidase and Polymerase Acidic Protein Mutation-Outcome Associations From a Single Center. [PDF]

Influenza Other Respir Viruses
ABSTRACT Background Antivirals are widely used to treat influenza, but potential resistance mutations remain a major challenge, and clinical data on key resistance mutations are limited. Methods We conducted a retrospective cohort study of 765 adults with RT‐PCR‐confirmed influenza A admitted to Ruijin Hospital, Shanghai, between 2019 and 2024 to ...

Antiviral Resistance Associated With Multiple Mutations Occurring in Seasonal Influenza A(H3N2) Virus in a Patient Treated With Oseltamivir. [PDF]

Clin Case Rep
ABSTRACT Our case highlights the importance of early diagnosis in respiratory illness and timely detection of drug resistance so that antiviral treatment can be initiated and modified, particularly for high‐risk groups. Vaccination and early, carefully dosed antiviral treatment are key to mitigating severe influenza cases, especially in ...
