Targets of influenza human T-cell response are mostly conserved in H5N1

mBio
Frequent recent spillovers of subtype H5N1 clade 2.3.4.4b highly pathogenic avian influenza (HPAI) virus into poultry and mammals, especially dairy cattle, including several human cases, increased concerns over a possible future pandemic.

Predicting Hotspots for Influenza Virus Reassortment

Emerging Infectious Diseases, 2013
The 1957 and 1968 influenza pandemics, each of which killed ≈1 million persons, arose through reassortment events. Influenza virus in humans and domestic animals could reassort and cause another pandemic.

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

Biological Reviews, EarlyView.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

H5N1 Clade 2.2 Polymorphism Tracing Identifies Influenza Recombination and Potential Vaccine Targets

, 2007
Highly pathogenic Influenza A H5N1 was first identified in Guangdong Province in 1996, followed by human cases in Hong Kong in 1997 1. The number of confirmed human cases now exceeds 300 and the associated Case Fatality Rate exceeds 60% 2.

Toward Predicting Pandemic Potential: A Comparative Analysis of Virus‐Host Interactions Between Diverse Influenza A Viruses and the Human Innate Immune System

PROTEOMICS, EarlyView.
ABSTRACT Zoonotic infections caused by influenza A viruses (IAVs) of animal origin are a major public health concern, as they may represent the initial step toward the emergence of a pandemic strain. The host range of IAVs is shaped by species‐specific virus‐host interactions, and several host barriers have been identified that restrict the adaptation ...

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

Wildlife Monographs, EarlyView.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

Truncation or Deglycosylation of the Neuraminidase Stalk Enhances the Pathogenicity of the H5N1 Subtype Avian Influenza Virus in Mallard Ducks [PDF]

Frontiers in Microbiology, 2020
H5N1 subtype avian influenza virus (AIV) with a deletion of 20 amino acids at residues 49-68 in the stalk region of neuraminidase (NA) became a major epidemic virus. To determine the effect of truncation or deglycosylation of the NA stalk on virulence, we used site-directed mutagenesis to insert 20 amino acids in the short-stalk virus A/mallard/Huadong/

Phylogenetic and molecular characteristics of Eurasian H9 avian influenza viruses and their detection by two different H9-specific RealTime reverse transcriptase polymerase chain reaction tests [PDF]

, 2013
Avian influenza viruses (AIVs) of the H9 haemagglutinin subtype are endemic in many Asian and Middle-East countries, causing mortality and morbidity in poultry.

Determining the Environmental and Ecological Factors Associated With Poultry Farm Spillover of Highly Pathogenic Avian Influenza (H5N1) in British Columbia, Canada

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction Highly pathogenic avian influenza (HPAI) H5N1, clade 2.3.4.4b is a global threat causing widespread outbreaks on poultry farms and high mortality among wild bird populations in Canada. Wild aquatic birds are generally recognised as key reservoir hosts for avian influenza viruses (AIV's).

Isolation and Genetic Characterization of Influenza A (Subtype H5N1) Virus from Crows in India [PDF]

Advances in Animal and Veterinary Sciences, 2014
We isolated two influenza A (subtype H5N1) viruses from crows in India, in 2011 and 2012. Nucleotide sequence of all eight genome segments of both the viruses (A/crow/India/ 11TI07/2011 and A/crow/India/01TR01/2012) was determined and used for analysis. The two iso - lates shared >99% nucleotide sequence identity in all the eight genes.
