Screening and Identification of B-Cell Epitopes in the P61 Protein of .

The P61 protein is an immunodominant antigen of that is observed in the sera from patients infected with the bacterium. However, the B-cell epitopes of are still unresolved. To identify the antigenic determinants of P61, we screened seven monoclonal antibodies (mAbs) against P61 protein that was expressed in the system.
