Zoonosis Update on H9N2 Avian Influenza Virus [PDF]

, 2013
Influenza A viruses infect various mammals like human, horse, pig and birds as well. A total of 16 hemagglutinin (HA) and 9 neuraminidase (NA) subtypes have been identified.

Chlamydia psittaci infection increases mortality of avian influenza virus H9N2 by suppressing host immune response

, 2016
International audienceAvian influenza virus subtype H9N2 (H9N2) and Chlamydia psittaci (C. psittaci) are frequently isolated in chickens with respiratory disease. However, their roles in co-infection remain unclear.

Investigating the role of segment 3 in H9N2 avian influenza virus pathogenicity [PDF]

H9N2 avian influenza viruses (AIV) are widespread in poultry populations worldwide, causing large economic losses. Reassortment events with other co-circulating AIV strains has led to an increased pathogenicity of H9N2 in poultry.

Continuing evolution of H9N2 influenza viruses in Southeastern China

, 2004
H9N2 influenza viruses are panzootic in domestic poultry in Eurasia and since 1999 have caused transient infections in humans and pigs. To investigate the zoonotic potential of H9N2 viruses, we studied the evolution of the viruses in live-poultry markets

PB2 mutations arising during H9N2 influenza evolution in the Middle East confer enhanced replication and growth in mammals.

PLoS Pathogens, 2019
Avian influenza virus H9N2 has been endemic in birds in the Middle East, in particular in Egypt with multiple cases of human infections since 1998. Despite concerns about the pandemic threat posed by H9N2, little is known about the biological properties ...

A Single Mutation N166D in Hemagglutinin Affects Antigenicity and Pathogenesis of H9N2 Avian Influenza Virus

Viruses, 2019
Some immune escape mutants of H9N2 virus and the corresponding mutations in hemagglutinin (HA) have been documented, but little is known about the impact of a single mutation on the antigenicity and pathogenesis of H9N2.

Novel genotypes of H9N2 influenza A viruses isolated from poultry in Pakistan containing NS genes similar to highly pathogenic H7N3 and H5N1 viruses.

PLoS ONE, 2009
The impact of avian influenza caused by H9N2 viruses in Pakistan is now significantly more severe than in previous years. Since all gene segments contribute towards the virulence of avian influenza virus, it was imperative to investigate the molecular ...

Vaccine Efficacy on the Novel Reassortant H9N2 Virus in Indonesia

, 2020
Vaccination is one of the leading methods of controlling the spread of the Avian Influenza (AI) viruses in Indonesia. The variety of circulating viruses and their ability to mutate must be followed by updating the vaccine master seed used in the field ...
