Genome Sequences of an H5N1 Highly Pathogenic Avian Influenza Virus Isolated from Vaccinated Layers in China in 2012

摘要

An H5N1 virus was isolated from vaccinated layers during an outbreak of highly pathogenic avian influenza (HPAI) in Ningxia, China, in 2012. Phylogenetic analysis revealed that the virus is a novel variant in clade 7.2, and the outbreak likely resulted from mutations in the viral hemagglutinin (HA) gene.
