| miliary tuberculosis | Usually a chronic tuberculosis infection where spread of the original primary infection has occurred via the patients lymphatic system (or bloodstream). Disseminated disease occurs primarily in the immunocompromised individual (for example AIDS, cancer patient). The elderly are at increased risk for dissemination. In disseminated disease, organs and tissues that can be affected include pericardium, peritoneum, larynx, bronchus, bone, joints, lymph nodes, stomach, meninges, eyes, kidneys and skin. Treatment is with INH, rifampin, ethambutol and other antibiotics. (27 Sep 1997) |

| multiple drug resistant tuberculosis | A strain of TB that does not respond to two or more standard anti-TB drugs. MDR-TB usually occurs when treatment is interrupted thus allowing mutations in the organism to occur that confer drug resistance. (09 Oct 1997) |
| mycobacterium tuberculosis | The Gram-positive bacterium that causes tuberculosis. (09 Oct 1997) |
| postprimary tuberculosis | Tuberculosis found in adults and characterised by lesions near the apex of an upper lobe, which may cavitate or heal with scarring without spreading to lymph nodes; theoretically, secondary tuberculosis may be due to exogenous reinfection or to reactivation of a dormant endogenous infection. Synonym: adult tuberculosis, postprimary tuberculosis, reinfection tuberculosis. (05 Mar 2000) |
| cutaneous tuberculosis | Pathologic lesions of the skin caused by Mycobacterium tuberculosis. Synonym: dermal tuberculosis, tuberculosis cutis. (05 Mar 2000) |
| healed tuberculosis | A scar or a calcified, fibrous, or caseous nodule in the lung pleura, lymph node, or other organ, resulting from previous tuberculosis that has regressed; reactivation is possible. Synonym: arrested tuberculosis, inactive tuberculosis. (05 Mar 2000) |
| primary tuberculosis | First infection by Mycobacterium tuberculosis, typically seen in children but also occurs in adults, characterised in the lungs by the formation of a primary complex consisting of small peripheral pulmonary focus with spread to hilar or paratracheal lymph nodes; may cavitate or heal with scarring or may progress. Synonym: childhood type tuberculosis. (05 Mar 2000) |
| secondary tuberculosis | Tuberculosis found in adults and characterised by lesions near the apex of an upper lobe, which may cavitate or heal with scarring without spreading to lymph nodes; theoretically, secondary tuberculosis may be due to exogenous reinfection or to reactivation of a dormant endogenous infection. Synonym: adult tuberculosis, postprimary tuberculosis, reinfection tuberculosis. (05 Mar 2000) |
| pulmonary tuberculosis | Tuberculosis of the lungs. (05 Mar 2000) |
| dermal tuberculosis | Pathologic lesions of the skin caused by Mycobacterium tuberculosis. Synonym: dermal tuberculosis, tuberculosis cutis. (05 Mar 2000) |
| disseminated tuberculosis | <microbiology> Usually a chronic tuberculosis infection where spread of the original primary infection has occurred via the patients lymphatic system (or bloodstream). Disseminated disease occurs primarily in the immunocompromised individual (for example AIDS, cancer patient). The elderly are at increased risk for dissemination. In disseminated disease, organs and tissues that can be affected include pericardium, peritoneum, larynx, bronchus, bone, joints, lymph nodes, stomach, meninges, eyes, kidneys and skin. Treatment is with INH, rifampin, ethambutol and other antibiotics. (11 Jan 1998) |
| inactive tuberculosis | A scar or a calcified, fibrous, or caseous nodule in the lung pleura, lymph node, or other organ, resulting from previous tuberculosis that has regressed; reactivation is possible. Synonym: arrested tuberculosis, inactive tuberculosis. (05 Mar 2000) |
| open tuberculosis | Pulmonary tuberculosis, tuberculous ulceration, or other form in which the tubercle bacilli are present in the excretions or secretions; in the lung, usually the result of cavity formation. (05 Mar 2000) |
| enteric tuberculosis | A complication of cavitary pulmonary tuberculosis usually resulting from expectoration and swallowing of bacilli that then infect areas of the digestive tract where there is relative stasis or abundant lymphoid tissue. See: tuberculous enteritis. (05 Mar 2000) |
| tuberculosis | <disease, microbiology> An infection caused by a species of Mycobacterium, still remains a major worldwide health problem. Although deaths from this disease have declined since the 1950's there has been some increase in tuberculosis incidence. Tuberculosis is transmitted from person to person by an aerosol of organisms suspended in tiny droplets that are inhaled. Acronym: TB (27 Sep 1997) |
