Method to Detect Antibodies Specific for Type-2 Turkey Astrovirus


Stacey Schultz-Cherry, Matthew Koci

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing an improved method for identifying animals exposed to turkey astrovirus-2.
OVERVIEWTurkey astrovirus-2 (TAstV-2) is associated with poultry enteritis and mortality syndrome (PEMS), a highly infectious emerging disease that affects young turkeys. Current methods for detecting animals infected with TAstV-2 require ongoing infection in the turkeys, as well as diagnostic facilities capable of performing molecular biology techniques. Results can also be greatly affected by sampling methods.
THE INVENTIONUW-Madison researchers have developed an improved method for identifying animals exposed to turkey astrovirus-2. In the method, a physiological fluid sample from an animal suspected of exposure is contacted with an antigen of TAstV-2. If the animal was exposed to TAstV-2, antibodies specific for the antigen of TAstV-2 are detected.
  • Identifying turkeys exposed to TAstV-2
  • Allows for routine surveillance of flocks
  • Does not require presence of virus to detect infection
  • Uses tools and techniques widely found in state diagnostic facilities
  • Assay can be performed in a 96-well plate
  • Results available within hours
  • May enable development of a vaccine for TAstV-2
