Characterization of the Whole-Genome Sequence of an H3N6 Avian Influenza Virus, Isolated from a Domestic Duck in Guangxi, Southern China.

ABSTRACT: 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 highest homology to H7N2 AIV. Phylogenetic analysis indicated that the eight AIV gene segments belonged to the Eurasian lineage. These findings provide scientific evidence of possible or potential mutations of H3N6 AIV circulating in waterfowl in southern China.

Avian Influenza Virus with Hemagglutinin-Neuraminidase Combination H3N6, Isolated from a Domestic Pigeon in Guangxi, Southern China.

Project description:The H3 subtype of avian influenza virus can provide genes for human influenza virus through gene reassortment, which has raised great concerns about its potential threat to human health. An H3N6 subtype of avian influenza virus was isolated from Guangxi Province, China, in 2009. All eight gene segments of the strain were sequenced. The sequence analysis indicated that this H3N6 virus was a nature reassortant virus. The genome sequences now can be used to understand the epidemiological and molecular characteristics of the H3N6 influenza virus in southern China.

Full-Genome Sequence Analysis of a Natural Reassortant H4N2 Avian Influenza Virus Isolated from a Domestic Duck in Southern China.

Project description:We report here the complete genome sequence of a novel reassortant H4N2 avian influenza virus strain, A/duck/Guangxi/125D17/2012(H4N2) (GX125D17), isolated from a duck in Guangxi Province, China in 2012. We obtained the complete genome sequence of the GX125D17 virus isolation by PCR, cloning, and sequencing. Sequence analysis revealed that this H4N2 virus strain was a novel reassortant avian in?uenza virus (AIV). Information about the complete genome sequence of the GX125D17 virus strain will be useful for epidemiological studies.

Genome Sequence of a Novel Reassortant H3N6 Avian Influenza Virus from Domestic Mallard Ducks in Eastern China.

Project description:Here, we report the complete genome sequence of an H3N6 avian influenza virus (AIV) isolated from domestic ducks in Jiangsu province of eastern China in 2010. Phylogenetic analysis showed that the H3N6 virus is a natural recombinant virus whose genes were derived from H3N8, H4N6, H6N6, H7N7, and H11N2 AIVs. This analysis will help to understand the molecular characteristics and evolution of the H3N6 influenza virus in eastern China.

Genetic Characterization of an Avian Influenza Virus H4N6 Strain Isolated from a Guangxi Pockmark Duck.

Project description: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.

Epidemiological surveillance of low pathogenic avian influenza virus (LPAIV) from poultry in Guangxi Province, Southern China.

Project description:Low pathogenic avian influenza virus (LPAIV) usually causes mild disease or asymptomatic infection in poultry. However, some LPAIV strains can be transmitted to humans and cause severe infection. Genetic rearrangement and recombination of even low pathogenic influenza may generate a novel virus with increased virulence, posing a substantial risk to public health. Southern China is regarded as the world "influenza epicenter", due to a rash of outbreaks of influenza in recent years. In this study, we conducted an epidemiological survey of LPAIV at different live bird markets (LBMs) in Guangxi province, Southern China. From January 2009 to December 2011, we collected 3,121 cotton swab samples of larynx, trachea and cloaca from the poultry at LBMs in Guangxi. Virus isolation, hemagglutination inhibition (HI) assay, and RT-PCR were used to detect and subtype LPAIV in the collected samples. Of the 3,121 samples, 336 samples (10.8%) were LPAIV positive, including 54 (1.7%) in chicken and 282 (9.1%) in duck. The identified LPAIV were H3N1, H3N2, H6N1, H6N2, H6N5, H6N6, H6N8, and H9N2, which are combinations of seven HA subtypes (H1, H3, H4, H6, H9, H10 and H11) and five NA subtypes (N1, N2, N5, N6 and N8). The H3 and H9 subtypes are predominant in the identified LPAIVs. Among the 336 cases, 29 types of mixed infection of different HA subtypes were identified in 87 of the cases (25.9%). The mixed infections may provide opportunities for genetic recombination. Our results suggest that the LPAIV epidemiology in poultry in the Guangxi province in southern China is complicated and highlights the need for further epidemiological and genetic studies of LPAIV in this area.
