Describes a phage-display method producing a fusion-protein antigen for specific, scalable serological detection of Newcastle disease antibodies in poultry.
Key Takeaways
- Phage-displayed immunodominant region of the NDV F protein was developed as a diagnostic antigen
- Displayed antigen detected NDV-GVII-specific antibodies in vaccinated chicken serum samples
- ELISA results using the phage antigen significantly correlated with hemagglutination inhibition test outcomes
