A Global Perspective on H9N2 Avian Influenza Virus [PDF]
Viruses, 2019 H9N2 avian influenza viruses have become globally widespread in poultry over the last two decades and represent a genuine threat both to the global poultry industry but also humans through their high rates of zoonotic infection and pandemic potential. H9N2 viruses are generally hyperendemic in effected countries and have been found in poultry in many ...

Persistence of avian influenza virus (H9N2) on plastic surface
Science of The Total Environment, 2022Plastics have been found to be colonized with pathogens and may become vectors for transmission of diseases. In this study, we evaluated the persistence of H9N2 avian influenza virus (AIV) on the surfaces of various plastics (PP, PE, PS, PET, PVC, PMMA) under different environmental conditions using glass and stainless steel for comparison. Our results

Endemic Variation of H9N2 Avian Influenza Virus in China
Avian Diseases, 2016Forty-two H9N2 subtype AIV strains were isolated from vaccinated commercial chickens in China from 2012 to 2015. Their HA genes had nucleotide sequence homology from 86.7% to 99.7%, and similarity to the classic vaccine strain was 88.6%-92.6%. A comparison was carried out with published HA genes (410 H9 strains) and whole genomes (306 strains) isolated

Genetic variation of the hemagglutinin of avian influenza virus H9N2
Journal of Medical Virology, 2011AbstractAvian influenza virus H9N2 has become the dominant subtype of influenza which is endemic in poultry. The hemagglutinin, one of eight protein‐coding genes, plays an important role during the early stage of infection. The adaptive evolution and the positively selected sites of the HA (the glycoprotein molecule) of H9N2 subtype viruses were ...

Pathogenicity of an Avian Influenza Virus Serotype H9N2 in Chickens
Avian Diseases Digest, 2008A low pathogenic avian influenza virus (AIV) serotype H9N2 affected many commercial flocks in the Middle East in late 1990s and early 2000s. Due to the varying pathogenicity ofAIV H9N2 reported in previous studies, this study was carried out to determine the pathogenicity of a Jordanian isolate of H9N2 in broiler and specific-pathogen-free (SPF ...

In order to develop a surrogate virus strain for production of an inactivated influenza vaccine against a human H9N2 virus, A/Hong Kong/1073/99 (HK1073: H9N2) was co-infected in embryonated chicken eggs with an apathogenic avian influenza virus, A/Duck/Czechoslovakia/56 (Dk/Cz: H4N6), for gene segment reassortment.

Development of a DAS-ELISA for detection of H9N2 avian influenza virus
Journal of Virological Methods, 2019H9N2 avian influenza virus is threatening animals and public health systems. Effective diagnosis is imperative to control the disease. Thus, we developed a panel of monoclonal antibodies (Mabs) against the H9N2 avian influenza virus (AIV) and implemented a double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) to detect the H9 viral ...
