Human Infection with Avian Influenza A(H9N2) Virus, Cambodia, February 2021 [PDF]

Emerging Infectious Diseases, 2021
In February 2021, routine sentinel surveillance for influenza-like illness in Cambodia detected a human avian influenza A(H9N2) virus infection. Investigations identified no recent H9N2 virus infections in 43 close contacts.

PA-X is an avian virulence factor in H9N2 avian influenza virus [PDF]

Journal of General Virology, 2021
Influenza A viruses encode several accessory proteins that have host- and strain-specific effects on virulence and replication. The accessory protein PA-X is expressed due to a ribosomal frameshift during translation of the PA gene. Depending on the particular combination of virus strain and host species, PA-X has been described as

Epidemiology and evolutionary dynamics of H9N2 avian influenza virus in Bangladesh. [PDF]

Emerg Microbes Infect
Low pathogenicity avian influenza (LPAI) H9N2 has been enzootic in Bangladeshi poultry since 2006. H9N2 outbreaks can decrease egg production and growth and pose a risk to human health. The role of avian hosts in the persistence, evolution, and dispersion of H9N2 is poorly understood in Bangladesh.

Diversity of the H9N2 Avian Influenza Virus in Shandong Province, China. [PDF]

Transbound Emerg Dis
H9N2 avian influenza virus (AIV) is one of the main pathogens causing respiratory disease in chicken; however, differentiating this virus from infectious bronchitis virus (IBV) and newcastle disease virus (NDV) only using clinical signs is difficult.

Genetic Evolution of H9N2 Avian Influenza Virus in Guangxi, China. [PDF]

Microorganisms
H9N2 avian influenza virus (AIV) is widely prevalent in poultry in China. To understand the genetic characteristics and evolution of H9N2 AIVs in Guangxi, southern China, the complete genomes of H9N2 AIVs from 1999–2023 were systematically analysed. Maximum likelihood (ML) trees indicated that H9N2 AIV gene sublineage diversity contributed to genotype ...

The inhibitory effect of Hypericum japonicum on H9N2 avian influenza virus. [PDF]

Adv Biotechnol (Singap)
AbstractThe H9N2 subtype of avian influenza virus (AIV) causes severe immunosuppression and high mortality in view of its frequent co-infection with other pathogens, resulting in significant economic losses in the poultry industry. Current vaccines provide suboptimal immune protection against H9N2 AIV owing to antigenic variations, highlighting the ...

H9N2 avian influenza virus in a Mediterranean gull [PDF]

Journal of Molecular and Genetic Medicine, 2009
Influenza A H9N2 is a low pathogenic virus present worldwide in domestic birds and, since the mid-1990s, it has been found to be endemic in poultry of southern China (Xu et al, 2007). Several cases of bird-to-human transmission have been reported in this area since 1999.

Is H9N2 Avian Influenza Virus a Pandemic Potential? [PDF]

Canadian Journal of Infectious Diseases and Medical Microbiology, 2009
To the Editor: H1N1 and H3N2 influenza virus subtypes continue to cause human disease (1,2), while avian influenza A H5 and H7 subtypes spread globally among birds with limited an inefficient transmission to humans (3,4). Results from recent ferret research on the H9N2 subtype has demonstrated an increased theoretical threat to humans from the ...

Vertical Transmission of H9N2 Avian Influenza Virus in Goose [PDF]

Frontiers in Microbiology, 2017
During a study on high mortality cases of goose embryo in Shandong Province, China (2014-2015), we isolated an H9N2 avian influenza virus (AIV) strain (A/goose/Shandong/DP01/2014, DP01), which was supposedly the causative agent for goose embryo death.

The immune system of chicken and its response to H9N2 avian influenza virus. [PDF]

Vet Q, 2023
Influenza A virus is a negative-sense single-stranded RNA virus that belongs to Orthomyxoviridae family. Based on the antigenic characteristics of hemagglutinin (HA) and neuraminidase (NA) influenza viruses are classified into multiple subtypes. H9N2 belongs to the low pathogenic Avian Influenza Viruses (AIVs) and is one of the widely spread viruses in
