Abstract

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.

Highlights

  • In this study, strain A/duck/Jiangsu/4/2010 (H3N6) was isolated from apparently healthy domestic mallard ducks in the Jiangsu province of eastern China

  • The complete genomic sequence was determined by reverse transcription-PCR (RTPCR) using a universal primer set [7]

  • The amino acid sequence at the cleavage site in the HA molecule is PEKQTR2G, which is characteristic of lowpathogenic Avian influenza viruses (AIV)

Summary

Introduction

Strain A/duck/Jiangsu/4/2010 (H3N6) was isolated from apparently healthy domestic mallard ducks in the Jiangsu province of eastern China. The complete genomic sequence was determined by reverse transcription-PCR (RTPCR) using a universal primer set [7]. MEGA5.0 software was used to analyze the genomic sequences.
