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.

The characterization of an orf virus (OV) isolated from skin lesions of a goat kid with severe, persistent, proliferative dermatitis, and designated orf virus-San Angelo 2000 (OV-SA00) strain, is described. The identity of OV-SA00 was confirmed by a combination of methods, including electron microscopy, amplification of specific fragments of viral DNA by polymerase chain reaction, restriction enzyme analysis of viral DNA and gene sequencing. Restriction endonuclease analyses of viral DNA and the protein profile studied by Western blot revealed differences between OV-SA00 strain and the profiles of other OV strains that have been published. The restriction enzyme profile of OV-SA00 was also different from the orf virus vaccine (OV-V) strain used to vaccinate this kid. Comparison of the nucleotide and deduced amino acid sequences indicated that OV-SA00 is closely related to OV-V strain, the Scottish OV strains orf11 and MRI Scab, and the human OV-CE/Shoe strain and more distant to bovine papular stomatitis virus (BPSV) reference strain and the pseudocowpox virus (PCPV)-MNV/Till strain. These results indicate that OV-SA00 is a strain of OV rather than a different parapoxvirus. Further studies are necessary to determine if the severity of orf-induced lesions in this goat kid was the result of individual host susceptibility factors.
