| Abstract: | The usefulness of the virus neutralization (VN) test, the enzyme-linked immunosorbent assay (ELISA), and the agar gel precipitin (AGP) test in differentiating antibodies to infectious bursal disease virus serotypes 1 and 2 was investigated. Sera examined were from chickens that were challenged with live virus or inoculated with inactivated oil-emulsion IBDV vaccines or were both challenged and inoculated. Antibodies to serotypes 1 and 2 were differentiated by the VN test but not by the ELISA, and the AGP test was less than satisfactory. |
