Arctiin suppresses H9N2 avian influenza virus-mediated inflammation via activation of Nrf2/HO-1 signaling

BMC Complementary Medicine and Therapies, 2021
Background H9N2 avian influenza viruses (AIVs) infect avian and mammalian hosts and provide internal genes for new emerging highly pathogenic avian viruses that cause severe pneumonia with high mortality, for which few medications are available. Arctiin,

Molecular immunophenotyping of lungs and spleens in naive and vaccinated chickens early after pulmonary avian influenza A (H9N2) virus infection [PDF]

, 2006
In a respiratory-infection-model with the avian influenza A H9N2 virus we studied lung and splenic immune reactions in chickens using a recently developed 5K chicken immuno-microarray.

Antigenic structure of the hemagglutinin of H9N2 influenza viruses [PDF]

Archives of Virology, 2008
The hemagglutinins (HAs) of H9 influenza viruses isolated from birds and mammals of different species were antigenically and genetically analyzed. Antigenic variants were selected from A/swine/Hong Kong/10/98 (H9N2) and A/duck/Hokkaido/13/00 (H9N2) in the presence of monoclonal antibodies (MAbs). Based on the reactivity patterns of these mutants with a

Characterization of H9N2 Avian Influenza Viruses Isolated from Poultry Products in a Mouse Model

Viruses, 2022
Low pathogenic H9N2 avian influenza viruses have spread in wild birds and poultry worldwide. Recently, the number of human cases of H9N2 virus infection has increased in China and other countries, heightening pandemic concerns. In Japan, H9N2 viruses are

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.

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.

Internal Gene Cassette From a Human-Origin H7N9 Influenza Virus Promotes the Pathogenicity of H9N2 Avian Influenza Virus in Mice

Frontiers in Microbiology, 2020
H9N2 avian influenza virus is one of the most widely circulating viruses in poultry and poses a huge potential threat to human health due to its frequent gene reassortment with other influenza viruses.

Comparative analysis of key immune protection factors in H9N2 avian influenza viruses infected and immunized specific pathogen–free chicken

Poultry Science, 2021
H9N2 avian influenza viruses (AIV) continue to circulate in vaccinated chicken flocks in China, which prompted us to investigate the differential immune protection factors induced by H9N2 AIV infection and immunization for analyzing the reason of ...

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 ...

The Multifaceted Zoonotic Risk of H9N2 Avian Influenza [PDF]

Veterinary Sciences, 2018
Poultry-adapted H9N2 avian influenza viruses (AIVs) are commonly found in many countries in Asia, the Middle East, Africa, and Europe, and although classified as low pathogenic viruses, they are an economically important disease. Besides the importance of the disease in the poultry industry, some H9N2 AIVs are also known to be zoonotic.
