Natural Reassortment of Eurasian Avian-Like Swine H1N1 and Avian H9N2 Influenza Viruses in Pigs, China

Emerging Infectious Diseases, 2022
Several zoonotic influenza A viruses detected in humans contain genes derived from avian H9N2 subtypes. We uncovered a Eurasian avian-like H1N1 swine influenza virus with polymerase basic 1 and matrix gene segments derived from the H9N2 subtype ...

Chicken Origin Tribasic H9N2 Avian Influenza Virus Induces Potent Early Antiviral Response With Low Pathogenicity in Japanese Quails. [PDF]

Vet Med Sci
This study gives valuable insights into host–pathogen interaction and confirms that the circulating tribasic H9N2 virus remains phenotypically low pathogenic in Japanese quails in Bangladesh but cause long‐term impairment of important productivity parameters (weight gain, laying rates).

Phage-Mediated Presentation of a Conserved HA2 Epitope From Influenza A Virus Elicits Significant IgY Antibody Responses in Broiler Chickens. [PDF]

Vet Med Sci
The conserved region of HA2 peptide of Influenza A virus was expressed on the surface of Protein VIII from M13 phage. Immunization of broiler chickens by this hybrid phage showed high levels of antibody responses, highlighting its potential as a promising tool for universal vaccine development against Influenza A virus.
