Other members of this genus--namely, orf virus, pseudocowpox
virus, and bovine papular stomatitis virus--commonly infect domestic ruminants and pose a minor occupational hazard to producers of sheep, goat, and cattle.
Recent isolates of parapoxvirus of Finnish reindeer (Rangifer tarandus tarandus) are closely related to bovine pseudocowpox
Other related viruses include pseudocowpox
in cows, and a disease called orf that affects sheep.
The genus Parapoxvirus (family Poxviridae, subfamily Chordopoxvirinae) comprises several members: orf virus (OV), bovine papular stomatitis virus (BPSV), pseudocowpox
virus (PCPV), and parapox of red deer in New Zealand virus (PVNZ).

To the long list of bovine viruses cited in this paper, it seems necessary to add another, the pseudocowpox virus, a widespread parapoxvirus that may infect humans.
Pseudocowpox virus is easily differentiated from orthopoxviruses such as vaccinia virus by the virus's peculiar form on transmission electron microscopy scan, but polymerase chain reaction is probably the best detection method (4).
Such diseases, characterized by the appearance of nodular and pustular lesions on bovine teats, are frequently related to viral infections such as bovine herpes mammillitis, pseudocowpox
, and cowpox infections (9-12).
