Research Project: Intervention Strategies to Control and Prevent Disease Outbreaks Caused by Avian Influenza and Other Emerging Poultry Pathogens

Location: Exotic and Emerging Avian Viral Diseases Research Unit

Project Number: 6612-32000-063-00
Project Type: Appropriated

Start Date: Oct 11, 2011
End Date: Oct 10, 2016

Objective:
1. Characterize variant and emerging avian influenza viruses in live poultry markets and commercial production systems. 2. Identify genetic and biological determinants of virulence, tissue tropism and host range of avian influenza virus. 3. Identify genetic and biological determinants of avian influenza virus susceptibility and resistance in avian species. 4. Improve existing diagnostic tests and testing strategies for avian influenza virus surveillance, detection, and recovery from disease outbreaks. 5. Develop new vaccine platforms designed to control and prevent avian influenza virus outbreaks.

Approach:
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. 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. 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.
