1. Acid-fast stain
A staining technique used to determine the cell wall property of a microorganism. After stained with dye such as hot carbol fuschin, an acid-fast organism, (.e.g. mycobacterium species) will retain the color in its cell wall after being washed with acid-alcohol.

2. Leprosy (Hansen's disease)
A chronic disease that causes lesions on the bones, skin, mucous membranes, and peripheral nervous system. People suffering from leprosy often lose sensation in their limbs and extremities because of nervous system lesions, and can unknowingly injure themselves and/or not care for wounds, thus causing further disfigurement. This disease, which was widely feared in ancient times and is still a problem in undeveloped countries, is caused by the Gram-positive , rod-shaped bacterium mycobacterium leprae. Armadillos can also catch this disease (there have been a few isolated incidents of people catching leprosy from them) and so are used in medical research on the illness.

3. Mycobacteria (Mycobacteriaceae)
A family of Gram-positive , rod-shaped bacteria that normally live in acidic conditions (soil, water, and dairy products); they include the bacteria that cause leprosy (mycobacterium leprae) and tuberculosis (mycobacterium tuberculosis).

4. Mycobacterium tuberculosis
The Gram-positive bacterium that causes tuberculosis .

5. Mycomycin
This antibiotic is used to treat tuberculosis (kills mycobacterium tuberculosis).

6. Tuberculin
A protein extracted from the tuberculosis bacterium mycobacterium tuberculosis. It is used in tests to determine if a person has been exposed to the bacteria and is in danger of coming down with the disease.

7. Tuberculin test
A test for previous infection with mycobacterium tuberculosis .

8. Tuberculosis (TB)
A highly infectious, potentially fatal disease of humans and animals caused by the Gram-positive bacteria mycobacterium tuberculosis. TB causes the formation of hard nodules (tubercules) and crusty dead spots in lung and bone tissue. People suffering from tuberculosis exhibit symptoms such as a bad cough and wasting debility. Prior to the development of antibiotic s such as penicillin , TB was known as "consumption" and was widely feared. Now, because TB infection is on the rise again as a common secondary infection accompanying AIDS , antibiotic-resistant strains have developed which could potentially cause major epidemics in the near future if alternate treatments aren't found.
