title: Immunogenicity and protective efficacy of solubilized merozoite-enriched Theileria sergenti immunogens. III. Characterization of immunodominant peptides.
abstract: Immunoblot analysis utilizing bovine sera from naturally or experimentally infected with Theileria sergenti were used to determine the immunodominant polypeptides of T. sergenti (Korean isolate). The previously recognized major bands, 18 kDa, 29 kDa, 34 kDa and 45 kDa, were excised after electrophoresis and transfer to PVDF membrane. The individual bands were sequenced. The 34 kDa polypeptide which was the most antigenic and immunogenic peptide was observed in the Western blot. However, Chou-Fasman prediction sites (antigenic site) for antigen determinants of the 45 kDa, 24 kDa, 29 kDa and 18 kDa polypeptide were 6, 4, 2 and 0, respectively. However, the 45 kDa polypeptide showed no reaction with anti-T, sergenti hyperimmune serum.
