Transient RNA structures underlie highly pathogenic avian influenza virus genesis

Highly pathogenic avian influenza viruses (HPAIVs) cause severe disease and high fatality in poultry1. They emerge exclusively from H5 and H7 low pathogenic avian influenza viruses (LPAIVs)2. Although insertion of a furin-cleavable multibasic cleavage site (MBCS) in the hemagglutinin gene was identified decades ago as the genetic basis for LPAIV-to ...

A Retrospective Cross‐Sectional Study (2009–2023): Exploring Influenza A(H1N1)pdm09 Antibody Time Series in Humans and Swine and Vaccine Coverage in Two Target Groups

Zoonoses and Public Health, Volume 73, Issue 4, Page 336-347, June 2026.
ABSTRACT Introduction Swine may act as ‘epidemiological bridges’ and reservoirs for the emergence of novel zoonotic influenza viruses with pandemic potential. While bidirectional exchange of influenza A viruses at the swine–human interface is well recognised, data on the extent of interspecies transmission are limited.

Large-scale avian influenza surveillance in wild birds throughout the United States. [PDF]

PLoS ONE, 2014
Avian influenza is a viral disease that primarily infects wild and domestic birds, but it also can be transmitted to a variety of mammals. In 2006, the United States of America Departments of Agriculture and Interior designed a large-scale, interagency ...

Emergence of a Highly Pathogenic Avian Influenza Virus from a Low-Pathogenic Progenitor [PDF]

Journal of Virology, 2014
ABSTRACT Avian influenza (AI) viruses of the H7 subtype have the potential to evolve into highly pathogenic (HP) viruses that represent a major economic problem for the poultry industry and a threat to global health. However, the emergence of HPAI viruses from low-pathogenic (LPAI) progenitor viruses currently is poorly understood.

Molecular Study on The Pathogenicity of Avian Influenza Virus

Indonesian Journal of Biotechnology, 2015
Highly pathogenic avian influenza virus (HPAI) differ from Low pathogenic avian influenza virus (LPAI) basedon multiple basic amino acid motif of the carboxylterminus of HA1, especially arginine and lysine.

First Serological Evidence of Avian Metapneumovirus and Infectious Laryngotracheitis Virus in Commercial Poultry in the Ashanti Region of Ghana

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study reports the first serological evidence of avian metapneumovirus and infectious laryngotracheitis virus in commercial poultry in Ghana. High aMPV seroprevalence (49%) and lower ILTV prevalence (7%) were detected, with some coinfection.

Subclinical Highly Pathogenic Avian Influenza Virus Infection among Vaccinated Chickens, China

Emerging Infectious Diseases, 2014
Subclinical infection of vaccinated chickens with a highly pathogenic avian influenza A(H5N2) virus was identified through routine surveillance in China. Investigation suggested that the virus has evolved into multiple genotypes. To better control transmission of the virus, we recommend a strengthened program of education, biosecurity, rapid ...
