Avian influenza [PDF]

open access: yesCurrent Allergy and Asthma Reports, 2005
The current epidemic of H5N1 highly pathogenic avian influenza in Southeast Asia raises serious concerns that genetic reassortment will result in the next influenza pandemic. There have been 164 confirmed cases of human infection with avian influenza since 1996.

Avian influenza

open access: yesVojnosanitetski pregled, 2006
A rapidly spreading, highly pathogenic avian influenza virus A H5N1 in the domestic poultry population has crossed the species barrier to humans and other mammalian species, thus, posing an increasing pandemic threat. The World Health Organization, other agencies, and countries worldwide are closely monitoring the prevalent influenza viruses and their ...

Avian influenza [PDF]

open access: yesEFSA Journal, 2017
Previous introductions of highly pathogenic avian influenza virus (HPAIV) to the EU were most likely via migratory wild birds. A mathematical model has been developed which indicated that virus amplification and spread may take place when wild bird populations of sufficient size within EU become infected.

Pathogenicity of H9N2 low pathogenic avian influenza viruses of different lineages isolated from live bird markets tested in three animal models: SPF chickens, Korean native chickens, and ducks

open access: yesPoultry Science, 2021
: Since its first appearance in 1996, H9N2 avian influenza virus (AIV) of the Y439 lineage persisted in Korean live bird markets (LBMs) until the last documented occurrence in 2018. However, in June 2020, the avian influenza surveillance program detected

Adsorptive mutation and N-linked glycosylation modulate influenza virus antigenicity and fitness

open access: yesEmerging Microbes and Infections, 2020
Influenza viruses have an error-prone polymerase complex that facilitates a mutagenic environment. Antigenic mutants swiftly arise from this environment with the capacity to persist in both humans and economically important livestock even in the face of ...

Single dose of multi-clade virus-like particle vaccine protects chickens against clade 2.3.2.1 and clade 2.3.4.4 highly pathogenic avian influenza viruses

open access: yesScientific Reports, 2021
Virus-like particles (VLPs) are recognized as an alternative vaccine platform that provide effective protection against various highly pathogenic avian influenza viruses (HPAIVs). Here, we developed multi-clade VLPs expressing two HAs (a chimera of clade

Evolutionary Dynamics of H5 Highly Pathogenic Avian Influenza Viruses (Clade 2.3.4.4B) Circulating in Bulgaria in 2019–2021

open access: yesViruses, 2021
The first detection of a Highly Pathogenic Avian Influenza (HPAI) H5N8 virus in Bulgaria dates back to December 2016. Since then, many outbreaks caused by HPAI H5 viruses from clade 2.3.4.4B have been reported in both domestic and wild birds in different
