Patent ID: 7919256

Claim:
A method for determining whether a subject has been infected with Borna disease virus (BDV), comprising: (a) providing a support having immobilized thereon p10 BDV synthetic antigen polypeptide and p24 BDV synthetic antigen polypeptide; (b) reacting the resulting support with a sample from a living body; and (c) assaying for both anti-BDV IgM antibody and anti-BDV IgG antibody which bind to said p10 BDV synthetic antigen polypeptide and said p24 BDV synthetic antigen polypeptide immobilized on said support, so as to detect said anti-BDV IgM antibody and/or anti-BDV IgG antibody in said sample, wherein said subject is determined to have been infected with BDV when said anti-BDV IgM antibody or said anti-BDV IgG antibody, or both said anti-BDV IgM antibody and said anti-BDV IgG antibody is detected, wherein the p10 BDV synthetic antigen polypeptide has an amino acid sequence as set forth in SEQ ID NO: 8, wherein the p24 BDV synthetic antigen polypeptide has an amino acid sequence as set forth in SEQ ID NO: 1.
