Latest Patents
Daxin Peng holds a patent for a recombinant H7N9 subtype avian influenza virus, inactivated marked vaccine, and its preparation method. This patent describes a recombinant H7N9 subtype avian influenza virus, utilizing strain JD/17 as the parent virus. The invention involves replacing a peptide sequence in the HA protein of strain JD/17 with a peptide sequence from the HA protein of H3 subtype. The strain JD/17 has a preservation number of CCTCC No. V201862. The results indicate that the rescued virus maintains similar biological characteristics to the parent virus, such as high HA titers and EID50. Chickens immunized with the marked inactivated and emulsified vaccine produce a high level of antibody, which can be distinguished from antibodies produced by chickens naturally infected with the H7N9 subtype avian influenza virus.
