| Epizootic aphtha | Biology & Biotechnology | An acute, highly contagious, viral infection of cloven-hooved animals (cattle, deer, sheep, goats, pigs, etc) characterized initially by vesicular lesions and subsequently by erosions of the epithelium of the mouth, nares, muzzle, feet, teats, udder, and rumen pillars. Very rarely lesions of foot-and-mouth disease occur in man (and have to be differentiated from hand, foot-and-mouth disease). Source: European Union. (references) | |
