paravaccinia

paravaccinia

 [par″ah-vak-sin´e-ah]
an infection due to the paravaccinia virus, a species of the genus Parapoxvirus that produces lesions similar to those of cowpox and orf on the udders and teats of milk cows. Paravaccinia may be transmitted to humans during milking, producing purple nodules on the fingers or adjacent areas; the lesions break down and crust and heal without scarring.

In mammals, numerous viruses are detectable in semen, including viruses that can cause disease in humans, such as Japanese encephalitis virus, foot and mouth disease virus, parainfluenza virus, and paravaccinia virus (6).
Negative-stain electron microscopy can confirm a parapoxvirus infection by demonstrating classic ovoid cross-hatched virions (Figure 2) but cannot distinguish orf virus from other parapoxviruses such as paravaccinia (pseudocowpox) virus; serologic testing has the same limitation.
