Mycobacterium Leprae

Mycobacterium leprae is a bacterium that causes leprosy, also known as "Hansen 's disease," a chronic infectious disease that damages the peripheral nerves and targets the skin, eyes, nose, and muscles. Leprosy can occur at all ages, from infancy to the elderly, but is curable in which treatments can prevent disabilities. It was discovered by the Norwegian physicist Gerhard Armauer Hansen in 1873 who was searching for the bacteria in the skin nodules of leprosy patients. It was the first bacterium that has been identified as causing human disease. It is a pathogenic, acid-fast, intracellular, pleomorphic bacterium. M. Leprae is an aerobic bacillus (rod-shaped bacterium) with parallel sides and round ends, surrounded by a typical mycobacterial waxy coating. This is closely related in size and shape to Mycobacterium tuberculosis. This bacterium often occurs in large numbers within lepromatous leprosy lesions that are usually grouped together as cigar bundles or arranged in a palisade. Leprosy stains with carbol fuchsin and not traditional Gram stain. It takes several weeks for the culture to mature.
