pseudocowpox

milk·ers' nod·ules

an infection of cows' udders by pseudocowpox virus, a member of the Poxviridae, that is transmitted to the fingers and hands of milkers, producing nodules and lymphangitis, and occasionally widespread papular or papulovesicular eruptions; human infection is transferable to uninfected cows.

pseudocowpox

an infectious disease of the skin of teats of cows caused by a paravaccinia virus. Typical lesions commence as erythema, progress to a vesicle, pustule or scab which is shed leaving a horseshoe-shaped ring of small scabs. Persons milking the cows may develop lesions on their hands. Called also milker's nodule.

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).
