To determin the accuracy of serological methods in detecting Borna-disease(BD) viral antibodies, 273 experimentally infected rabbit sera were compared by using indirect immunofluorescence antibody test(IFA), serum neutralization test(SN) and enzyme-linked immunosorbent assay(ELISA). One hundred twenty-three serum samples had BD viral antibodies detected by IFA. CELISA antibodies to BD virus were also present in the same one hundred twenty-three serum samples. However, neutralization test antibodies to BD virus were present in 27 of the in rabbit serum samples. Neutralization test was sensitive in comparison with KFA and CELISA. In comparison with IFA, CELISA was both sensitive and specific in detecting BD viral antibodies. These results extend observations made with laboratory animals to the diagnosis of naturally infected animals.

The value of the cell enzyme-linked immunosorbent assay as a possible replacement for the indirect immunofluorescence antibody test for the estimation of antibodies against BD virus was assessed in four animal models. The serum antibody response was measured by both assay systems;the variability of both tests was less than one diluent step, and correlation of the two tests was assessed using regression analysis. The study showed that the all four animal models gave satisfactory correlation of CELISA and IFA. There, CELISA is acceptable for use in mouse, rabbit, chicken and rat models.
