Substitutions near the hemagglutinin receptor-binding site determine the antigenic evolution of influenza A H3N2 viruses in U.S. swine [PDF]

open access: yes, 2014
Swine influenza A virus is an endemic and economically important pathogen in pigs, with the potential to infect other host species. The hemagglutinin (HA) protein is the primary target of protective immune responses and the major component in swine ...

Compositional Constraint Is the Key Force in Shaping Codon Usage Bias in Hemagglutinin Gene in H1N1 Subtype of Influenza A Virus

open access: yesInternational Journal of Genomics, 2014
It is vital to unravel the codon usage bias in order to gain insights into the evolutionary forces dictating the viral evolution process. Influenza A virus has attracted attention of many investigators over the years due to high mutation rate and being ...

Seroepidemiologic Effects of Influenza A(H1N1)pdm09 in Australia, New Zealand, and Singapore

open access: yesEmerging Infectious Diseases, 2013
To estimate population attack rates of influenza A(H1N1)pdm2009 in the Southern Hemisphere during June–August 2009, we conducted several serologic studies. We pooled individual-level data from studies using hemagglutination inhibition assays performed in

Diagnostic approach for the differentiation of the pandemic influenza A(H1N1)v virus from recent human influenza viruses by real-time PCR. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: The current spread of pandemic influenza A(H1N1)v virus necessitates an intensified surveillance of influenza virus infections worldwide. So far, in many laboratories routine diagnostics were limited to generic influenza virus detection only.

Second-generation nitazoxanide derivatives: thiazolides are effective inhibitors of the influenza A virus [PDF]

open access: yes, 2018
Aim: The only small molecule drugs currently available for treatment of influenza A virus (IAV) are M2 ion channel blockers and sialidase inhibitors. The prototype thiazolide, nitazoxanide, has successfully completed Phase III clinical trials against ...

Mouse Models of Influenza Infection with Circulating Strains to Test Seasonal Vaccine Efficacy

open access: yesFrontiers in Immunology, 2018
Influenza virus infection is a significant cause of morbidity and mortality worldwide. The surface antigens of influenza virus change over time blunting both naturally acquired and vaccine induced adaptive immune protection.

Genesis and pathogenesis of the 1918 pandemic H1N1 influenza A virus [PDF]

open access: yes, 2014
The source, timing, and geographical origin of the 1918–1920 pandemic influenza A virus have remained tenaciously obscure for nearly a century, as have the reasons for its unusual severity among young adults.

Universal protection against influenza viruses by multi-subtype neuraminidase and M2 ectodomain virus-like particle

open access: yesPLoS Pathogens, 2022
Annual influenza vaccination is recommended to update the variable hemagglutinin antigens. Here, we first designed a virus-like particle (VLP) displaying consensus multi-neuraminidase (NA) subtypes (cN1, cN2, B cNA) and M2 ectodomain (M2e) tandem repeat (

Distribution of influenza virus types by age using case-based global surveillance data from twenty-nine countries, 1999-2014

open access: yesBMC Infectious Diseases, 2018
Background Influenza disease burden varies by age and this has important public health implications. We compared the proportional distribution of different influenza virus types within age strata using surveillance data from twenty-nine countries during ...
