Differentiation of parapoxviruses by application of orf virus-specific monoclonal antibodies against cell surface proteins.
|
| Abstract |
Monoclonal antibodies were produced against orf virus-specified cell surface proteins in an attempt to develop reagents capable of differentiating between members of the Parapoxviridae. Two immunization protocols were used to induce an anti-orf response in BALB/c mice, one of which resulted in virus replication in the recipient. The monoclonal antibodies produced were tested for crossreactivity with bovine papular stomatitis virus (BPS) and milker's node virus (MNV) by indirect immunofluorescence assay (IFA) and immunoblotting. The results indicate that significant antigenic overlap exists between isolates of orf, MNV and BPS, even at the level of specificity provided by monoclonal antibodies. One monoclonal antibody reacted strongly in IFA with orf virus isolates, very weakly with MNV, and not at all with BPS. On immunoblots this same antibody recognized a 40-43 kDa protein in orf virus-infected cells, and also a 45-48 kDa protein in cells infected with MNV or BPS virus. The data suggest that it may be possible to define parapoxvirus strains on the basis of small variations in specific virus-directed cell surface proteins.
