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.
