SPECIAL SECTION

Viral Disease - Pseudo Cow Pox

Etiology

Para poxvirus

Epidemiology

Primarily affects cows in early lactation. Low, but progressive, morbidity in herd. Spread during milking

Clinical findings

Vesicles, pustules, formation of a thick scab elevated by granulating tissue. Horseshoe shaped ring of small scabs surrounding granulating tissue

Clinical pathology

Vesicle fluid for electron microscopy

Differential diagnosis

Differentiation of those diseases in which lesions of the teat are prominent is dealt with in the preceding section on cowpox.

Diagnostic confirmation

Electron microscopy

Treatment

Antiseptics and emollient ointment, locally applied ointments of various kinds appear to have little effect on the lesions. The recommended treatment includes the removal of the scabs, which should be burned to avoid contaminating the environment, application of an astringent preparation, such as triple dye, after milking and an emollient ointment just before.

Control

Milking hygiene
