About the Avian Diagnostics Section

Our Avian Diagnostics section offers disease testing services and flock health support for the U.S. poultry industry including:

  • Commercial poultry
  • Backyard flocks
  • Waterfowl flocks
  • Upland gamebird facilities
  • Pet birds

We provide a wide array of avian disease diagnostic services, including avian influenza virus and Newcastle disease virus testing, virus isolation in embyronated eggs and Salmonella Enteritidis culture and real-time PCR.

We conduct a number of research projects, both in the US and in developing countries. We also conduct training courses for local veterinarians and animal health officials in developing countries.

We also provide educational opportunities for commercial poultry and upland gamebird producers and backyard poultry owners.
