[Objective] The B cell epitopes for VP73 protein of African swine fever virus was predicted. [ Method] Based on the analysis of the amino acid sequence and the flexible regions of VP73 protein, the B cell epitopes for VP73 protein of African swine fever virus were predicted by method of Kyte-Doolittie, Emini and Jameson-Wolf. [Result] The B cell epitopes were located at or adjacent to the N-terminal No. 11 - 18,26 -48,73 -82,136 - 150,159 - 174,181 - 189,191 - 210,247 - 276,279 - 295,313 - 323 and 382 - 392. [Conclusion] The multi-parameters analytic method was adopted to predict the B cell epitopes for VP73 protein of African swine fever virus, which laid solid foundation for further characterizing the protein of VP73 and researching epitope vaccine.
