| 520 | 3 | |a Porcine parvovirus type 1 (PPV1) is a major causative agent of embryonic and fetal death in swine. The PPV1 VP2 protein is closely associated with viral immunogenicity for eliciting neutralizing antibodies, but its antigenic structures have been largely unknown. We generated three monoclonal antibodies (MAbs) against baculovirus-expressed recombinant PPV1 VP2 protein. A PEPSCAN analysis identified the minimal B cell linear epitopes of PPV1 VP2 based on these MAbs. Three core epitopes, 228QQITDA233, 284RSLGLPPK291, and 344FEYSNGGPFLTPI356, were defined and mapped onto three-dimensional models of the PPV1 virion and VP2 monomer. The epitope 228QQITDA233 is exposed on the virion surface, and the other two are located inside the protein. An alignment of the PPV1 VP2 amino acid sequences showed that 284RSLGLPPK291 and 344FEYSNGGPFLTPI356 are absolutely conserved, whereas 228QQITDA233 has a single substitution at residue 233 in some (S→A or T). We developed a VP2 epitope-based indirect enzyme-linked immunosorbent assay (iELISA) to test for anti-PPV1 antibodies. In a comparative analysis with an immunoperoxidase monolayer assay using 135 guinea pig sera, the VP2-epitope-based iELISA had a concordance rate of 85.19%, sensitivity of 83.33%, and specificity of 85.47%. MAb 8H6 was used to monitor VP2 during the PPV1 replication cycle in vitro with an indirect immunofluorescence assay, which indicated that newly encapsulated virions are released from the nucleus at 24h postinfection and the PPV1 replication cycle takes less than 24h. This study provides valuable information clarifying the antigenic structure of PPV1 VP2 and lays the foundations for PPV1 serodiagnosis and antigen detection. | |
