| 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) |
| tuberculosis, avian | A variety of tuberculosis affecting various birds, including chickens and ducks. It is caused by mycobacterium avium and characterised by tubercles consisting principally of epithelioid cells. It may be transmitted to other animals including man. (12 Dec 1998) |
| tuberculosis, bovine | An infection of cattle caused by mycobacterium bovis. It is transmissible to man and other animals. (12 Dec 1998) |
| tuberculosis, cardiovascular | Tuberculosis of the heart, pericardium, or blood vessels. (12 Dec 1998) |
| tuberculosis, cutaneous | Tuberculosis of the skin. It includes scrofuloderma and tuberculid, but not lupus vulgaris, which is lupus. (12 Dec 1998) |

| tuberculosis, gastrointestinal | Gastric and/or enteric tuberculosis. This condition is marked by spreading ulcers and diarrhoea. (12 Dec 1998) |
| tuberculosis: gastrointestinal manifestations | <radiology> Ileocaecal area, most common site (80-90%), Stierlin sign, Fleischner sign, thickened ileocaecal valve, fissures, ulcers, sinus tracts, fistulas, perforation, colon, segmental involvement; especially on right side, ulcerating colitis with pseudopolyps, hourglass stricture, wall thickening, gastroduodenal area, simultaneous involvement of pylorus and duodenum, stenotic pylorus with gastric outlet obstruction, narrowed antrum (linitis plastica appearance), ulcers, thickened folds, antral fistula, oesophagus, least common site, ulcers, stricture, mass, sinus tracts (12 Dec 1998) |
