H9N2 avian influenza virus in a Mediterranean gull [PDF]

Journal of Molecular and Genetic Medicine, 2009
Influenza A H9N2 is a low pathogenic virus present worldwide in domestic birds and, since the mid-1990s, it has been found to be endemic in poultry of southern China (Xu et al, 2007). Several cases of bird-to-human transmission have been reported in this area since 1999.

Lack of Evidence for Human-to-Human Transmission of Avian Influenza A (H9N2) Viruses in Hong Kong, China 1999

Emerging Infectious Diseases, 2002
In April 1999, isolation of avian influenza A (H9N2) viruses from humans was confirmed for the first time. H9N2 viruses were isolated from nasopharyngeal aspirate specimens collected from two children who were hospitalized with uncomplicated, febrile ...

Chlamydia psittaci Triggers the Invasion of H9N2 Avian Influenza Virus by Impairing the Functions of Chicken Macrophages

Animals, 2020
In a pilot study, simultaneous infection with Chlamydia psittaci (C. psittaci) and H9N2 virus induced 20% mortality and severe avian airsacculitis, shedding light on animal models of poultry respiratory diseases.
