Avian Influenza Virus H9N2 Survival at Different Temperatures andpHS

Avian Diseases Digest, 2010
The H9N2 avian influenza virus (AIV) subtype has become endemic in Israel since its introduction in 2000. The disease has been economically damaging to the commercial poultry industry, in part because of the synergistic pathology of coinfection with other viral and/or bacterial pathogens.

Evaluation of Pathogenic Potential of Avian Influenza Virus Serotype H9N2 in Chickens

Avian Diseases, 2003
Recently seven isolates of avian influenza virus (AIV) serotype H9N2 recovered from an outbreak of AI were analyzed on the basis of their biological and molecular characteristics. All the isolates belonged to the low-pathogenicity group of AIV. To further evaluate their pathogenic potential in association with other organisms, an isolate was inoculated

Identification of avian influenza virus subtype H9N2 in chicken farms in Indonesia

Preventive Veterinary Medicine, 2018
Avian influenza virus subtype H9N2 (AIV-H9N2) has become established in domestic poultry in Asia and Africa. AIV-H9N2 has not been reported previously in Indonesia. Here we describe the presence of AIV-H9N2 in chicken farms in Indonesia. Ninety-nine cases were observed in various provinces in Indonesia.

Avian Influenza Virus H9N2: Characterization and Control Strategies

2007
Control of Avian Influenza (AI) infection is a highly topical subject of major economicimportance for the worldwide poultry industry at the national level and for international trade.H9N2 viruses are endemic in poultry throughout Asia and the Middle East, causing major losses inproduction. Moreover, these viruses pose wider threats since they have been

Experimental infection of non-human primates with avian influenza virus (H9N2)

Archives of Virology, 2013
Several cases of humans infected with the H9N2 avian influenza virus (AIV) have been described since 1999; however, the infectivity and pathogenicity of H9N2 in humans is not well defined. A non-human primate model in rhesus macaques was developed to study H9N2 virus infections as a means of better understanding the pathogenesis and virulence of this ...

Genetic evolution of the H9N2 avian influenza virus in Korean poultry farms

Virus Genes, 2012
We performed whole genome sequencing of 22 H9N2 avian influenza viruses (AIV) isolated from domestic laying hens on farms between 2005 and 2008, and compared the sequences with viruses previously reported in Asia. A previous study revealed that two antigenically distinct sublineages were established within the MS96 lineage by antigenic drift since the ...

Global genetic variation and transmission dynamics of H9N2 avian influenza virus

Transboundary and Emerging Diseases, 2017
The H9N2 influenza viruses are extensively circulating in the poultry population, and variable genotypes can be generated through mutation, recombination and reassortment, which may be better adapted to infect a new host, resist drug treatment or escape immune pressure. The LPAI H9N2 viruses have the potential to evolve towards high levels of virulence

Evaluation of Transmission Route and Replication Efficiency of H9N2 Avian Influenza Virus

Avian Diseases Digest, 2010
A/Chicken/Beijing/1/94 (Ck/BJ/1/94) avian influenza virus (AIV), a prototype of the H9N2 subtype, is phylogenetically similar in its hemagglutinin (HA) and neuraminidase (NA) genes to A/Chicken/Shanghai/F/98 (Ck/SH/F/98; H9N2) AIV, a natural reassortant between different sublineages.

Zhonghua shi yan he lin chuang bing du xue za zhi = Zhonghua shiyan he linchuang bingduxue zazhi = Chinese journal of experimental and clinical virology, 2003
To understand whether the avian influenza A(H9N2) virus can infect men or not.Seroepidemiological surveys for avian (H9N2) virus in human, chickens and pigs were conducted. The specimens for viral isolation were taken from throat of patients with influenza like disease, as well as from chickens, then the specimens were inoculated into embryonated ...
