Is leprosy an organism?
Leprosy, also known as Hansen’s disease (HD), is a long-term infection by the bacteria Mycobacterium leprae or Mycobacterium lepromatosis. Infection can lead to damage of the nerves, respiratory tract, skin, and eyes.
Which gram causes leprosy?
M leprae is the causative agent associated with leprosy, which has been recognized as an infectious disease for the last 2 millennia. M leprae was discovered as the causative agent in 1873. The acid fast, gram-positive bacillus is an obligate intracellular organism with a predilection for Schwann cells and macrophages.
What is the mode of transmission of leprosy?
The infection spreads from person to person by nasal secretions or droplets. Leprosy rarely spreads from chimpanzees, mangabey monkeys, and nine-banded armadillos to humans by droplets or direct contact. Susceptibility to getting leprosy may be due to certain human genes.
How do people get leprosy?
Scientists currently think it may happen when a person with Hansen’s disease coughs or sneezes, and a healthy person breathes in the droplets containing the bacteria. Prolonged, close contact with someone with untreated leprosy over many months is needed to catch the disease.
Who is prone to leprosy?
Leprosy can develop at any age but appears to develop most often in people aged 5 to 15 years or over 30. It is estimated that more than 95% of people who are infected with Mycobacterium leprae do not develop leprosy because their immune system fights off the infection.
How do you prevent leprosy?
How can leprosy be prevented? The best way to prevent the spread of leprosy is the early diagnosis and treatment of people who are infected. For household contacts, immediate and annual examinations are recommended for at least five years after last contact with a person who is infectious.
What is the name of the bacteria that causes leprosy?
Related Pages. Hansen’s disease (also known as leprosy) is an infection caused by slow-growing bacteria called Mycobacterium leprae. It can affect the nerves, skin, eyes, and lining of the nose (nasal mucosa). With early diagnosis and treatment, the disease can be cured.
What kind of disease is leprosy or Hansen’s disease?

How does leprosy affect the body and nervous system?
Leprosy is a slowly developing, progressive disease that damages the skin and nervous system. Leprosy is caused by an infection with Mycobacterium leprae or M. lepromatosis bacteria. Early symptoms begin in cooler areas of the body and include loss of sensation.
Are there different types of leprosy in different people?
There are multiple forms of leprosy described in the literature. The forms of leprosy are based on the person’s immune response to M. leprae. A good immune response can produce the so-called tuberculoid form of the disease, with limited skin lesions and some asymmetric nerve involvement.

What kind of disease is caused by Mycobacterium leprae?
Mycobacterium leprae, the cause of leprosy. Leprosy is a chronic infectious disease caused by Mycobacterium leprae. It damages peripheral nerves and can affect the skin, eyes, nose and muscles. Nerve injury in leprosy can cause severe disabling deformities.
How long does it take for leprosy to develop?
Hansen’s disease (also known as leprosy) is an infection caused by bacteria called Mycobacterium leprae. These bacteria grow very slowly and it may take up to 20 years to develop signs of the infection. The disease can affect the nerves, skin, eyes, and lining of the nose (nasal mucosa).
