Abstract

An H12N8 subtype avian influenza virus (AIV) was isolated from a wild bird in China in 2011. It is the first report of isolation of the H12N8 subtype AIV in Asia. Phylogenetic analysis results suggested it is a reassortant, and all eight gene segments belong to the Eurasian gene pool.

Highlights

  • An H12N8 subtype avian influenza virus (AIV) was isolated from a wild bird in China in 2011

  • In order to understand the ecology and evolution of AIVs in wild birds in central China, we conducted a continuous survey from November 2011 to April 2012 in the Hunan East Dongting Lake National Nature Reserve, Yueyang, Hunan, China, an important overwintering habitat of East Asian migratory birds, located at the middle reaches of the Yangtze River

  • We isolated an H12N8 subtype AIV from wild aquatic bird feces in November 2011 and named the strain A/wild goose/ Dongting/C1037/2011 (H12N8), which is the first report of the detection of an H12N8 subtype AIV in Asia

Summary

Introduction

An H12N8 subtype avian influenza virus (AIV) was isolated from a wild bird in China in 2011. Wild aquatic birds are natural reservoirs of all subtypes of avian influenza viruses (AIVs) [1,2,3]. Long-term surveillance of AIVs in wild aquatic birds in North America and Europe has occurred since 1976 and 1998, respectively [4, 5].
