Vertical Transmission of H9N2 Avian Influenza Virus in Goose [PDF]

Frontiers in Microbiology, 2017
During a study on high mortality cases of goose embryo in Shandong Province, China (2014-2015), we isolated an H9N2 avian influenza virus (AIV) strain (A/goose/Shandong/DP01/2014, DP01), which was supposedly the causative agent for goose embryo death.

A small-scale study on airborne transmission of H9N2 avian influenza virus under field conditions

Journal of Infection in Developing Countries, 2018
Introduction: H9N2 avian influenza viruses (AIV) can transmit in chicken flocks through direct contact and aerosols. Nevertheless, data on airborne transmission of AIV is very limited, especially under field conditions. To fill this literature gap, this

Influenza A H9N2: Aspects of Laboratory Diagnosis [PDF]

Journal of Clinical Microbiology, 1999
Influenza A viruses of subtype H9N2 are now considered to be widespread in poultry ([1][1]). They have recently been isolated from pigs originating from southern China ([5][2]) and from two children with influenza-like symptoms in Hong Kong ([2][3]).

Phylogeography of Avian influenza A H9N2 in China [PDF]

BMC Genomics, 2014
During the past two decades, avian influenza A H9N2 viruses have spread geographically and ecologically in China. Other than its current role in causing outbreaks in poultry and sporadic human infections by direct transmission, H9N2 virus could also serve as an progenitor for novel human avian influenza viruses including H5N1, H7N9 and H10N8.

Influenza A(H9N2) Virus, Burkina Faso [PDF]

Emerging Infectious Diseases, 2017
We identified influenza A(H9N2) virus G1 lineage in poultry in Burkina Faso. Urgent actions are needed to raise awareness about the risk associated with spread of this zoonotic virus subtype in the area and to construct a strategy for effective prevention and control of influenza caused by this virus.

Avian-to-human transmission of H9N2 subtype influenza A viruses: Relationship between H9N2 and H5N1 human isolates [PDF]

Proceedings of the National Academy of Sciences, 2000
In 1997, 18 cases of influenza in Hong Kong (bird flu) caused by a novel H5N1 (chicken) virus resulted in the deaths of six individuals and once again raised the specter of a potentially devastating influenza pandemic. Slaughter of the poultry in the live bird markets removed the source of infection and no further human cases of H5N1 infection have ...
