    • n vaccinia A specific eruptive disease occurring in cattle, especially in milch cows. It is characterized by an eruption, at first papular, then changing to vesicular, situated usually at the junction of the teats with the udder. The vesicle is umbilicated, the margin being more elevated than the center, and contains a clear yellowish fluid. The skin surrounding it is somewhat inflamed, reddish in color, and indurated. The vesicle increases in size up to about the tenth day, when the contents become more opaque, and a crust begins to form. This crust increases in size for a few days, and then dries up and falls off at about the end of the third week. During the height of the disease there may be a little fever and loss of appetite, and the yield of milk may be somewhat diminished; but in general the constitutional disturbance is slight. It is by inoculation with lymph taken from the vesicles in this disease as it occurs in the cow or in the human subject that immunity against smallpox is conferred upon man. See vaccination and vaccine. Also vaccina and cowpox.
