Schematic representation of putative genomic compositions of the four H4N6 AIVs isolated in this study and their possible parent viruses.

Abstract

<p>The eight gene segments (from top to bottom) in each virus are PB2, PB1, PA, HA, NP, M, and NS. Each color represents a separate virus background. The simplified schematic illustration is based on nucleotide-distance comparison and phylogenetic analysis.</p
