Genesis of avian influenza H9N2 in Bangladesh

Emerging Microbes and Infections, 2014
Avian influenza subtype H9N2 is endemic in many bird species in Asia and the Middle East and has contributed to the genesis of H5N1, H7N9 and H10N8, which are potential pandemic threats.

Infectious Bronchitis Virus Infection Increases Pathogenicity of H9N2 Avian Influenza Virus by Inducing Severe Inflammatory Response

Frontiers in Veterinary Science, 2022
Infectious bronchitis virus (IBV) and H9N2 avian influenza virus (AIV) are frequently identified in chickens with respiratory disease. However, the role and mechanism of IBV and H9N2 AIV co-infection remain largely unknown.

Chicken Origin Tribasic H9N2 Avian Influenza Virus Induces Potent Early Antiviral Response With Low Pathogenicity in Japanese Quails. [PDF]

Vet Med Sci
This study gives valuable insights into host–pathogen interaction and confirms that the circulating tribasic H9N2 virus remains phenotypically low pathogenic in Japanese quails in Bangladesh but cause long‐term impairment of important productivity parameters (weight gain, laying rates).

Development of an Inactivated Avian Influenza Virus Vaccine against Circulating H9N2 in Chickens and Ducks

Vaccines, 2023
Avian influenza virus (AIV) subtype H9N2 is the most widespread AIV in poultry worldwide, causing great economic losses in the global poultry industry. Chickens and ducks are the major hosts and play essential roles in the transmission and evolution of ...

Egyptian Fruit Bats (Rousettus aegyptiacus) Were Resistant to Experimental Inoculation with Avian-Origin Influenza A Virus of Subtype H9N2, But Are Susceptible to Experimental Infection with Bat-Borne H9N2 Virus

Viruses, 2021
Influenza A viruses (IAV) of subtype H9N2, endemic in world-wide poultry holdings, are reported to cause spill-over infections to pigs and humans and have also contributed substantially to recent reassortment-derived pre-pandemic zoonotic viruses of ...

Variation and Molecular Basis for Enhancement of Receptor Binding of H9N2 Avian Influenza Viruses in China Isolates

Frontiers in Microbiology, 2020
Currently, H9N2 avian influenza viruses (H9N2 AIVs) globally circulate in poultry and have acquired some adaptation to mammals. However, it is not clear what the molecular basis is for the variation in receptor-binding features of the H9N2 AIVs.

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 ...

Investigation of seroepidemiology of H9N2 influenza in native poultry of different regions of Khuzestan province

Journal of Zoonotic Diseases, 2022
Bird flu is one of the most critical and dangerous viral diseases that have been reported all over the world. Although H9N2 viruses are considered a threat by themselves, they are known to be very zoonotic as donors of gene segments to other viruses ...
