| mycobacterium leprae | A species of gram-positive, aerobic bacteria that causes leprosy in man. Its organisms are generally arranged in clumps, rounded masses, or in groups of bacilli side by side. (12 Dec 1998) |

| Hansen's bacillus | A species of gram-positive, aerobic bacteria that causes leprosy in man. Its organisms are generally arranged in clumps, rounded masses, or in groups of bacilli side by side. (12 Dec 1998) |
| hansen disease | <infectious disease> Caused by Mycobacterium leprae, an obligate intracellular parasite that survives lysosomal enzyme attack by possessing a waxy coat. Leprosy is a chronic disease associated with depressed cellular (but not humoral) immunity, the bacterium requires a lower temperature than 37쵣 and thrives particularly in peripheral Schwann cells and macrophages. Only humans and the nine banded armadillo are susceptible. (18 Nov 1997) |

| Hansen's disease | <infectious disease> Leprosy is a chronic granulomatous infection of humans by the bacterium Mycobacterium leprae. Leprosy affects the superficial tissues, especially the skin and peripheral nerves. It is estimated that there are between 10 and 20 million persons affected with leprosy in the world. Leprosy is most common in tropical climates (even as close as Mexico), but quite rare in the United States. Ninety percent of the cases diagnosed in the U.S. Have occurred in immigrants from leprosy-endemic countries. Some sporadic reports of leprosy have come out of Hawaii and the Gulf Coastal areas of the U.S. (27 Sep 1997) |
| Fosdick-Hansen-Epple test | A test for determining dental caries activity based on a solution of powdered human enamel in a saliva-glucose-enamel mixture. (05 Mar 2000) |
| mycobacterium | <microbiology> An organism of the genus Mycobacterium. (18 Nov 1997) |
| Mycobacterium abscessus | A species originally found in a traumatic infection of the knee. Synonym: Mycobacterium abscessus. (05 Mar 2000) |
| mycobacterium, atypical | So-called atypical species of the genus mycobacterium. They are also called tuberculoid bacilli, i.e.: m. Buruli (see m. Ulcerans), m. Chelonae, m. Duvalii, m. Flavescens, m. Fortuitum, m. Gilvum, m. Gordonae, m. Intracellulare (see mycobacterium avium complex), m. Kansasii (kansas), m. Marinum, m. Obuense, m. Scrofulaceum, m. Szulgai, m. Terrae, m. Ulcerans, m. Xenopi. (12 Dec 1998) |
| mycobacterium avium | A bacterium causing tuberculosis in domestic fowl and other birds. In pigs, it may cause localised and sometimes disseminated disease. The organism occurs occasionally in sheep and cattle. It should be distinguished from the m. Avium complex, which infects primarily humans. (12 Dec 1998) |
| mycobacterium avium complex | A serious opportunistic infection caused by two similar bacteria (Mycobacterium avium and Mycobacterium intercellulare) found in the soil and dust particles. In AIDS, MAC can spread through the bloodstream to infect lymph nodes, bone marrow, liver, spleen, spinal fluid, lungs and intestinal tract. Typical symptoms of MAC include night sweats, weight loss, fever, fatigue, diarrhoea and enlarged spleen. MAC is usually found in people with CD4 counts below 100. MAC is also called MAI. (09 Oct 1997) |
| mycobacterium avium complex disease | <infectious disease> A disease process caused by infection by the organism Mycobacterium avium intracellulare. Almost unheard of in a patient with a normal functioning immune system, this can be a common infection in those with advanced HIV infection. (27 Sep 1997) |
| Mycobacterium avium-intracellulare complex | An opportunistic agent of people with AIDS. Difficult to treat because Mycobacterium is resistant to many antibiotics. May also cause chronic lower respiratory tract infections. (05 Mar 2000) |
| mycobacterium avium-intracellulare infection | Nontuberculous infection occurring in humans. This condition is frequently associated with pulmonary disease and recently recognised as an opportunistic infection in aids patients. (12 Dec 1998) |
| mycobacterium bovis | The bovine variety of the tubercle bacillus. It is called also mycobacterium tuberculosis var. Bovis. (12 Dec 1998) |
