| 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 chelonae | A species of gram-positive, aerobic bacteria commonly found in soil and occasionally isolated from sputum. It causes postoperative wound infections as well as gluteal abscesses. (12 Dec 1998) |
| Mycobacterium chelonae subsp. abscessus | A species originally found in a traumatic infection of the knee. Synonym: Mycobacterium abscessus. (05 Mar 2000) |
| mycobacterium fortuitum | A rapid-growing, nonphotochromogenic species that is potentially pathogenic, producing lesions of lung, bone, or soft tissue following trauma. It has been found in soil and in injection sites of humans, cattle, and cold-blooded animals. (12 Dec 1998) |
| mycobacterium haemophilum | A species of gram-positive, aerobic bacteria that causes granulomatous or ulcerating skin lesions in immunosuppressed persons. This organism owes its name to its requirement for growth of high levels of iron, conveniently supplied as blood, haem, or ferric ammonium citrate. (12 Dec 1998) |
| mycobacterium infections | Infections with bacteria of the genus mycobacterium. (12 Dec 1998) |
| mycobacterium infections, atypical | Infections with so called atypical mycobacteria (tuberculoid bacilli): m. Kansasii (kansas), m. Marinum, m. Scrofulaceum, m. Flavescens, m. Gordonae, m. Obuense, m. Gilvum, m. Duvali, m. Szulgai, m. Intracellulare (see mycobacterium avium complex), m. Xenopi (littorale), m. Ulcerans, m. Buruli, m. Terrae, m. Fortuitum (minetti, giae), m. Chelonae. (12 Dec 1998) |
| Mycobacterium intracellulare | A species found in lung lesions and sputum of humans; may cause bone and tendon-sheath lesions in rabbits; some strains are pathogenic for mice. Recently linked to opportunistic infections in humans. Synonym: Battey bacillus. (05 Mar 2000) |
| mycobacterium kansasii | A slow-growing, photochromogenic species that is the aetiologic agent of a tuberculosis-like disease in humans and is frequently isolated from human pulmonary secretions or tubercles. The incidence of infection is sharply increased among immunocompromised individuals. (12 Dec 1998) |
| 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) |
| mycobacterium lepraemurium | The aetiologic agent of rat leprosy, also known as murine leprosy. (12 Dec 1998) |
