What is Newcastle disease virus?
Newcastle disease virus (NDV) is a highly contagious virus affecting birds, particularly poultry.
Why is accurate antigen preparation important?
Accurate antigen preparation is crucial for reliable serological testing and effective disease surveillance.
What is a hemagglutination inhibition assay?
It is a common method used to detect antibodies against viruses like NDV by measuring their ability to inhibit hemagglutination.
How does the back-titration method work?
Back-titration involves diluting a known quantity of antigen to determine its hemagglutination titer accurately.
What technologies can enhance serological testing?
