These objectives include a combination of basic and applied research to give us the knowledge and tools to effectively control avian influenza virus (AIV). The first objective focuses on characterizing new and emerging strains of AIV, initially by genome sequencing and analysis, then by pathogenesis and transmission studies, and finally by antigenic characterization. The second objective will elucidate specific viral factors involved in pathogenesis and virulence at a molecular level including utilizaiton of variant isolates initially characterized under objective 1. Experimental challenge in poultry and wild bird species will be conducted. The third objective will investigate the viral factors involved in transmission and host adaptation of AIV among avian species with reverse genetics and pathogensis studies. Transmission in chickens and pekin ducks will be evaluated. Under objective 4 diagnostic tests will be improved by characterizing novel isolates to assure specificity and by adapting novel technologies to improve sentivity and specificity. New vaccines will be developed and evaluated through a variety of approaches including antigenic and molecular characterization for objective 5.
