An account is given of the close correlations that exist between virus strains of bovine papular stomatitis, orf, pseudocowpox, and milker's nodule. Reference is made to literature data on natural infection of man with the above virus strains. A report then is presented on experimental infection of human volunteers, using paravaccine birus. While fairly tough and elevated nodules, 4 mm to 5 mm in diameter, were produced on the probends' skin, no re-isolation of virus was achieved.

The DNAs of eight parapoxviruses (four stomatitis papulosa viruses isolated from infected calves, a pseudocowpox virus isolated from a teat lesion of an infected cow and three orf viruses, one isolated from an infected sheep and two isolated from human infections) were analysed in CsCl gradients. The mole % of G+C was calculated from the buoyant density and found to be approx. 63% for all virus isolates examined. Parapoxvirus DNA thus has by far the highest G+C content of all poxvirus DNAs so far examined.

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.

In a search for new fingerprinting probes for use with sheep, repeat sequences derived from five poxviruses, an iridovirus and a baculovirus were screened against DNA from sheep pedigrees. Probes constructed from portions of the parapox viruses, orf virus and papular stomatitis virus and the baculovirus from the alfalfa looper, Autographa californica, nuclear polyhedrosis virus all gave fingerprint patterns. Probes from three other poxviruses and an iridovirus did not give useful banding patterns.

Eight stomatitis papulosa (SP), four orf and two milker's nodes (MN) virus isolates were compared by restriction enzyme analysis. Considerable genetic heterogeneity was found not only between isolates belonging to the three different taxonomic groups but also between members of the same group. This heterogeneity precludes classification of parapoxviruses simply by comparison of their DNA cleavage patterns. Restriction maps were therefore prepared for 12 parapoxvirus DNAs. Fragments from defined regions of the genome were then selected and used as probes for cross-hybridizations to all other parapoxvirus DNAs. DNA fragments derived from an internal region of the genome hybridized strongly to all parapoxvirus isolates examined. In contrast, cross-hybridization of the end region of the DNA molecule was observed only between members of the same virus group. Molecular hybridization as a means of classifying parapoxvirus isolates is discussed.

Superficial epidermal surgical removal of localized bullous lesions of viral origin is recommended. An example is presented in which the patient had what we have termed "farmyard pox." This is our generic label for the clinically indistinguishable parapox viral infections acquired from farm animals, which include orf, milker's nodules, and the pox of bovine papular stomatitis. The surgery is simple and rapid, and completely removes the lesions. This eliminates the possibility of enlargement and contagion, and also promotes rapid healing.

Inasmuch as orf, milker's nodules and bovine papular stomatitis pox are clinically identical in man and are induced by currently indistinguishable parapox viruses, we propose a new generic term 'farmyard pox' for these diseases. This affords the clinician a diagnosis based on a common set of clinical and electron microscopic findings rather than one based on an uncertain or even misleading history. A case in point is reported in which the history failed to reveal a specific animal source of the virus, but electron microscopy confirmed the presence of parapox infection.

Neutralizing and non-neutralizing monoclonal antibodies against parapoxviruses (PPV) were generated by immunizing BALB/c-mice with gradient-purified PPV Orf D-1701 or purified envelopes. Epitope specificity studies identified three distinct epitopes localized in the virus envelope. These antigenic sites allowed a differentiation between orf and stomatitis papulosa viruses. For a rapid diagnosis of parapoxviruses transmission-electron microscopy, immunofluorescence- or immunoperoxidase-staining, antigen capture ELISA, and polymerase-chain-reaction were used.

There are three accepted members of the parapoxvirus genus, orf virus (OV), papular stomatitis virus (PSV), and pseudocowpox virus (PCV). OV is maintained in sheep and goats and PSV and PCV in cattle. Restriction endonuclease profiles of the DNA derived from representatives of these established members of the genus were compared with profiles from a parapoxvirus recently isolated from red deer. In no case did the profile of this latter virus (DPV) resemble those generated from the other parapoxviruses. Southern blot hybridization using total DPV DNA as a probe revealed homology between DPV and the central regions of the genomes of the other parapoxviruses but not to their terminal regions. These results indicate that the genome of DPV is as different from the genomes of the three accepted members of the genus as the latter are from each other and argue for the inclusion of DPV as a new member of the parapoxvirus genus.

Monoclonal antibodies (Mabs) were generated in BALB/c mice immunized with gradient-purified particles, envelopes and cores of intracellular mature orf virus D-1701. Three distinct antigenic sites were identified in this virus strain. Their topographical relationships was determined by pairwise epitope specificity studies in competition ELISAs. One MAb (class IgM) neutralized virus infectivity. Four micrograms/ml purified IgM gave a 50% reduction of 100 PFU of orf virus D-1701. As shown by immunogold electron microscopy (ELMI), all MAbs reacted with epitopes localized on the virus surface. Western blotting analysis demonstrated that two proteins of a Mr of 39kDa and 22kDa were the main targets for the Mabs. Cross-reactivity studies of several parapoxviruses (PPV) differentiated stomatitis papulosa virus strains from orf virus and milker's node virus (MNV) by a missing antigenic site.
