Complete Genome Sequence of a New H9N2 Avian Influenza Virus Isolated in China
نویسندگان
چکیده
The complete genomic sequence of a new H9N2 avian influenza virus (AIV), isolated in northwestern China, was determined. Sequence and phylogenetic analyses based on the sequences of eight genomic segments revealed that the isolate is phylogenetically related to the Y280-like sublineage.

Characterization of an Avian Influenza Virus H9N2 Strain Isolated from a Wild Bird in Southern China
We isolated an avian influenza virus H9N2 strain from a wild bird in the Guangxi Province of southern China in 2013 named A/turtledove/Guangxi/49B6/2013(H9N2) (GX49B6). We aimed to understand the genetic characters of the GX49B6 strain by analyzing the complete genome sequence. The results showed that our isolated strain has features of low pathogenic avian influenza viruses and viruses that in...
متن کاملFull Genome Sequence of a Natural Reassortant H9N2 Avian Influenza Virus Isolated from Domestic Ducks in Jiangsu Province, China
In this study, the complete genomic sequence of a novel reassortant H9N2 avian influenza virus (AIV) from domestic ducks in eastern China was reported. Phylogenetic analysis showed that seven of the eight genes were all highly homologous to the chicken-origin H9N2 viruses, whereas the PB2 gene was homologous to the human-origin H1N1 virus, which suggested that domestic ducks might play a key ro...
متن کاملNeuraminidase gene sequence analysis of avian influenza H9N2 viruses isolated from Iran
Influenza A viruses possesses two virion surface glycoproteins including haemagglutinin (HA) and neuraminidase (NA). The NA plays an important role in viral replication and promotes virus release from infected cells and facilitates virus spread throughout the body. To find out any genomic changes that might be occurred on NA gene of avian influenza circulating viruses, we have genetically analy...
متن کاملSequence Analysis and Phylogenetic Study of Hemagglutinin Gene of H9N2 Subtype of Avian Influenza Virus Isolated during 1998-2002 in Iran
Sequence analysis and phylogenetic study of hemagglutinin (HA) gene of H9N2 subtype of avian influenza virus isolates (outbreaks of 1998-2002) in Tehran province (Iran) were studied. Two sets of forward and reverse primers in highly conserved regions, based on sequences of HA gene in Genbank, were designed. PCR products of a 430-bp fragment of 16 isolates were sequenced and then were aligned wi...

Background and Aims: Avian Influenza (AI) H9N2 subtype was first reported to infect turkeys in the United States in 1966 and has been panzootic in Europe and Asia. The impact of avian influenza caused by H9N2 viruses in Iran is now significantly more severe than in previous years. Methods: Sequence analysis and phylogenetic study of the complete coding region Polymerase A (PA) gene of H9N2 subt...
