Zambezi ulcer Zam·be·zi ul·ceran ulcer, usually single, about 3 cm in diameter, on the foot or leg, occurring in laborers in the Zambezi Delta in Africa; the ulcer has a sloughing surface, but does not spread and produces no constitutional symptoms or glandular enlargement; it is associated with the presence of a spirillum and a large fusiform bacillus; one attack seems to confer a partial immunity. |
