Mycobacterium- Leprae
Mycobacterium leprae is a bacterium that causes leprosy, also known as "Hansen’s disease", which is a chronic
infectious disease that compensations the peripheral nerves and targets the skin, eyes, nose, and muscles.
Leprosy can arise at all ages from infancy to elderly, but is curable in which treatments can avert debilities. It was discovered in 1873 by the Norwegian physician Gerhard Armauer Hansen, who was examining for the bacteria in the skin knobs of patients with leprosy. It was the first bacterium to be recognized as causing disease in humans.
It is an intracellular, pleomorphic, acid-fast, pathogenic bacterium. M. leprae is an aerobic bacillus (rod-shaped bacterium) with parallel sides and round ends, bounded by the characteristic waxy covering unique to mycobacteria. This bacterium recurrently ensues in great numbers within the grazes of lepromatous
leprosy that are usually grouped together like bundles of cigars or prepared in a palisade. These patches have dry, light, hairless centers, accompanied by a lack of sensation at the skin. The loss of sensation may also expand as a result of invasion of the peripheral sensory nerves. The macule on the cutaneous website online of access and the loss of ache sensation are key scientific indicators that an character has a tuberculoid shape of leprosy.

The second form of
leprosy is the "lepromatous" form, in which the microbes proliferate inside the macrophages on the web site of entry. They also grow in the epithelial
tissues of the face and ear lobes. The suppressor T-cells that are caused are severa, but the epithelioid and large
cells are rare or absent. With cellular-mediated
immunity impaired, huge numbers of M. Leprae appear within the macrophages and the inflamed patients broaden papules on the access website online, marked by a folding of the pores and skin. Gradual destruction of cutaneous nerves lead to what's called "conventional lion face." Extensive penetration of this microbe might also lead to extreme body harm; for example the loss of bones, hands, and feet.
