[Molecular mechanism affecting route of transmission for H9N2 subtype AIV].

Wei sheng wu xue bao = Acta microbiologica Sinica, 2009
The available evidence suggests that H9 subtype avian influenza virus (AIV) did not circulate in Chicken flocks in China until the early 1990s. However, the pandemic of H9 subtype AI, which started in summer of 1998, spread very rapidly to more than 20 provinces within several months.

Muscovy duck retinoic acid-induced gene I (MdRIG-I) functions in innate immunity against H9N2 avian influenza viruses (AIV) infections

Veterinary Immunology and Immunopathology, 2015
Retinoic acid inducible gene I (RIG-I) is a cytosolic pattern recognition receptor that senses pathogen-associated molecular patterns (PAMPs). Muscovy duck (Cairina moschata) is a large duck different from other species of ducks, and is more susceptible to some microbial pathogens.

Some ethanobotanically important plants from Cholistan area for anti avian influenza virus (AIV) H9N2 screening

Pakistan Journal of Pharmaceutical Sciences, 2019
Avian influenza or bird flu is a common problem of domestic and wild birds. Some of its strains are able to cross the species barrier and cause infection in various members of class Mammalia. In view of relatively lesser efficacy of vaccines, antiviral therapies remain the only choice for the sustenance of mammals acquiring this highly devastating ...

Construction of recombinant Marek's disease virus (MDV) lacking the meq oncogene and co-expressing AIV-H9N2 HA and NA genes under control of exogenous promoters

Journal of Biotechnology, 2014
To develop a recombinant Marek's disease virus (rMDV1) co-expressing the hemagglutinin gene (HA) and neuramidinase gene (NA) from a low pathogenic avian influenza virus (LPAIV) H9N2 strain and lacking the meq oncogene that shares homology with the Jun/Fos family of transcriptional factors, a wild strain of MDV GX0101 was used as parental virus, the HA ...

Synergistic virulence of H9N2 AIV and APEC co-infection in laying hens involves a critical role for macrophage-mediated hyper-inflammation via the MAPK/NF-κB axis

Veterinary Microbiology
H9N2 avian influenza virus (AIV) is a low-pathogenic subtype virus that is widely prevalent in poultries worldwide. Although H9N2 infection alone typically causes mild or asymptomatic disease in chickens, it facilitates secondary bacterial infections, such as those caused by avian pathogenic Escherichia coli (APEC).
