Avian Influenza — China
Abstract
——–
To analyze the whole genome sequence and pathogenicity of H9N2 subtype influenza virus carried by pet dogs in Guangxi, we amplified and sequenced the whole genome by RT-PCR. The amino acid homology and evolutionary tree were analyzed in DNA-Star and MEGA 6.0 software, and pathogenicity was studied through mouse infection experiments. 8 gene segments of 13 H9N2 strains were derived from 5 different lineages, which belonged to the new genotype. The amino acid sequence
