Genetic Characterization of an Avian Influenza Virus H4N6 Strain Isolated from a Guangxi Pockmark Duck
نویسندگان
چکیده
An H4N6 subtype avian influenza virus was isolated from a pockmark duck in southern China in November 2013 and named A/duck/Guangxi/149D24/2013 (H4N6). All eight gene segments of the strain were sequenced. Sequence analysis indicated that this H4N6 virus was a natural reassortant virus. This H4N6 virus has two basic amino acids in the cleavage site of hemagglutinin 1 (HA1) and HA2, and the amino acid motif of cleavage site was PEKASRGLF, which is the typical characteristic of the low-pathogenic avian influenza virus. This study will help understand the epidemiology and molecular characteristics of avian influenza virus in pockmark ducks.

A field strain of H3N6 avian influenza virus (AIV), A/duck/Guangxi/175D12/2014(H3N6), was isolated from a native duck in Guangxi Province, southern China, in 2014. All of the eight AIV gene segments were sequenced, and sequence results revealed that there were 11 amino acid deletions at the NA stalk region. The NA, PB2, and NP genes showed highest homology to H5N6 AIV, and the PA gene showed hi...

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...

BACKGROUND: The H9N2 subtype of avian influenzaviruses (AIVs) has been isolated in multiple avian species inmany European, Asian, African and American countries. Sincethe first outbreak of H9N2 virus in Iran in 1998, this virus haswidely circulated throughout the country, resulting in majoreconomic losses in chicken flocks. Several amino acids in thevirus ribonucleoprotein (RNP) complex includi...
