COW-POX

n. Ku8'u4-po2x. Lat., vaccinia, variolas, vaccince [Jenner]. Fr., cowpox, vaccine. Ger., Kuhpocken. It., vaccina. Sp., vacuna. A specific contagious disease of bovine animals (chiefly milch-cows), communicable to man and to various animals by inoculation, but not by effluvium; characterized by lesions resembling those of small-pox, usually on the udder in cows, with swelling and tenderne of the parts about the teats, due to injury in milking, accompanied by slight fever. It is thought by some to be a disease sui generis, by others to be a modified form of horsepox, and by others to be a modified form of small-pox. The liquid contents of the pocks (lymph, vaccine) are used in the practice of vaccination, and the disease is now propagated purposely in calves for furnishing supplies of that material. Cf. VACCINIA and VACCINE. Casual c.-p. C.-p. occurring as the result of contagion from an accidental or unknown source. Natural c.-p., Spontaneous c.-p. C.-p. that is not the result of artificial inoculation. Spurious c.-p. Fr., faux cowpox. Any affection of the udder in cows resembling c.-p. [A, 301.J COWQUAKE, [s. 432]
