Molecular Basis for antigenic variation in H9N2 and impact on vaccination
H9N2 LPAI (Low Pathogenic Avian Influenza) is causative agent for egg performance issues in laying hens. H9 causes follicle atresia, internal & external egg defects due to inflammation response in the oviduct.
He briefed on molecular and antigenic variances in H9N2. Antigenic cartography as tool to select right vaccine seed.
