Mycobacterium leprae

Hansens Disease

DefensesVaccine : There isn't a vaccine for mycobacterium leprae

DefensesBehavorial : Wash your hands with soap after sneezing or coughing and periodically throughout the day. Also wash your hands before eating as touching food with dirty hands can spread bacteria

The incubation period is difficult to determine. It probably ranges from nine months to 20 years with an average of four years for tuberculoid leprosy and eight years for lepromatous leprosy.Duration : If taking medicine, pauci-bacillary, a type with not many bacteria will go away in six months. For multi-bacillary, with medicine, it will take 12-24 months to disappear. Without medicine, leprosy is permanent.

Brief DescriptionMycobacterium leprae mostly found in warm tropical countries, is a gram-positive bacterium Mycobacterium leprae causes leprosy, which is also known as Hansen's disease. It is part of the family Mycobacteriaceae, which is the same family as the bacteria that cause tuberculosis (Mycobacterium tuberculosis). Mycobacterium leprae grow slowly and mainly affect the skin, nerves, and mucous membranes. The ability for Mycobacterium leprae to survive and cause damage within humans is poorly understood.

Attacks : . Most scientists believe that Mycobacterium leprae transmission occurs from person to person in respiratory droplets. While this may be one mode of transmission, over half of the people who develop leprosy have no confirmed contact with an infected person. The degree of susceptibility of the person, the extent of exposure, and environmental conditions are among the factors that could influence Mycobacterium leprae transmission. Outcome It infects the skin , peripheral nerves , front portion of the eyes , upper respitory passages , testes , hands , and feet Symptoms include skin stiffness and dryness , loss if fingers and toes , severe pain , muscle weakness

Treatment : Without treatment, leprosy causes "progressive and permanent damage to skin, nerves, limbs and eyes.” Losses of fingers, toes, and blindness can ensue if no steps are taken to curb the disease. Leprosy can cause loss of feeling in the extremities, making it easy to badly damage arms and legs, fingers and toes.
