Here, we report the complete genome sequence of an H6N8 avian influenza virus (AIV) isolated from wild waterfowl in Poyang Lake, China, in 2016. Phylogenetic analysis showed that it was a novel reassortant AIV between domestic ducks and wild waterfowl. The finding of this study is helpful for our understanding of the ecology and the evolutionary characteristics of H6 subtypes of AIV in birds.

Avian influenza caused by avian influenza virus (AIV) has a negative impact on poultry production. Low-pathogenic AIV (LPAIV) is naturally present in wild birds, and the introduction of the virus into domestic poultry is assumed to occur through contact with wild birds and by human activity, including the movement of live and dead poultry, and fomites such as clothing and vehicles. At present, ...

Avian influenza (AI) is an infectious disease caused by avian influenza viruses (AIVs) which belong to the influenza virus A group. AI causes tremendous economic losses in poultry industry and pose great threatens to human health. Active serologic surveillance is necessary to prevent and control the spread of AI. In this study, a protein microarray using nucleoprotein (NP) of H5N1 AIV expressed...

To determine the effectiveness of ducks as sentinels for avian influenza virus (AIV) infection, we placed mallards in contact with wild birds at resting sites in Germany, Austria, and Switzerland. Infections of sentinel birds with different AIV subtypes confirmed the value of such surveillance for AIV monitoring.

Wild waterfowl are primary reservoirs of avian influenza viruses (AIV). However the role of sea ducks in the ecology of avian influenza, and how that role differs from freshwater ducks, has not been examined. We obtained and analyzed sera from North Atlantic sea ducks and determined the seroprevalence in those populations. We also tested swab samples from North Atlantic sea ducks for the presen...

We report the complete genome sequence of a natural recombinant H9N2 avian influenza virus (AIV) that was isolated from a wild bird in the Republic of Korea in 2005. The genomic sequence and phylogenetic analyses showed that this virus contains six genes of North American lineage AIV and two genes of Eurasian lineage AIV. These data are beneficial for investigating the ecology and epidemiology ...

New antiviral therapy for pandemic influenza mediated by the H9N2 avian influenza virus (AIV) is increasingly in demand not only for the poultry industry but also for public health. Aptamers are confirmed to be promising candidates for treatment and prevention of influenza viral infections. Thus, we studied two DNA aptamers, A9 and B4, selected by capillary electrophoresis-based systemic evolut...

Avian influenza virus (AIV) can infect birds and mammals, including humans, and are thus a serious threat to public health. Vaccination is vital for controlling AIV circulation. In this study, we generated a recombinant lactobacillus expressing the NP-M1-DCpep of H9N2 avian influenza virus and evaluated the activation effect of NC8-pSIP409-NP-M1-DCpep on dendritic cells (DCs) in a mouse model. ...

Although wild birds are the recognized source and reservoir for all subtypes of avian influenza viruses (AIV), the complex interaction among these diverse host and virus populations has not received adequate attention. A general concept of AIV epidemiology in wild birds exists; however, the presence of highly pathogenic avian influenza (HPAI) H5N1 viruses in wild birds has reinforced the need f...

In 1994, an H7N2 subtype avian influenza virus of low pathogenicity was detected in live-bird markets (LBMs) of the Northeast United States. Since that time the H7N2 virus continues to circulate in the LBMs despite efforts to eradicate the virus by market closures followed by extensive cleaning and disinfection. Since 1996, the LBMs have been implicated as the source of virus in five outbreaks ...
