Abstract
The full-genome sequence of A/swine/Henan/1/2010, a strain of influenza A virus isolated in central China, was determined. Phylogenetic analyses show that its eight genomic segments are human-like, and some of its segments have appeared in swine H1N2, swine H1N1, and human H1N2 influenza viruses.
Highlights
The full-genome sequence of A/swine/Henan/1/2010, a strain of influenza A virus isolated in central China, was determined
Viruses of the H1N1, H1N2, and H3N2 subtypes are enzootic in swine [3, 4]
This will produce new virus strains that may not be recognized by antibodies to earlier influenza virus strains, or it may result in a new influenza virus that can infect humans and has an HA protein or HA and NA protein combination that has not been seen in humans for many years
Summary
The full-genome sequence of A/swine/Henan/1/2010, a strain of influenza A virus isolated in central China, was determined. Swine influenza virus (SIV) contains eight separate negativesense RNA segments and belongs to the Orthomyxoviridae family [1, 2]. The influenza A viruses are divided into subtypes based on two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA).
