[The prevalence of abdominal tuberculosis and the specific features of its detection]
Abstract:
A hundred and thirteen case histories of patients with isolated and generalized forms of abdominal tuberculosis were analyzed. The patients' age was 15 to 79 years; there were 86 (76.1%) males and 27 (23.9%) females. The patients were admitted more frequently from other tuberculosis facilities (66.7%) and less frequently from general hospitals (33.3%). In 62 (54.9%) cases, abdominal tuberculosis showed a complicated course. The residents of Moscow and its region, predominantly the unemployed (85.8%), prevailed in the structure of detected patients with abdominal tuberculosis. In the period of 2001 to 2004, there was a rise in the incidence of new-onset abdominal tuberculosis, its rate increased from 4.4 (2001) to 8.3% (2004) of the total number of patients admitted to Moscow clinical hospital No. 7 for extrapulmonary tuberculosis admitted. This gives no way of considering this site of tuberculosis to be rare. In the structure of abdominal tuberculosis, its generalized forms were prevalent (86.7%), which was associated with the late detection of abdominal tuberculosis and the significant increase in the number of HIV-infected patients from 14.3 (2000) to 33.3% (2004). Abdominal organ lesions were more frequently observed in severe generalized pulmonary processes, such as disseminated (45.1%), infiltrative (18.6%) or fibrocavernous (15.9%) tuberculosis. An algorithm of diagnosis of abdominal tuberculosis and the rates of its detection by various studies are presented in the paper. Abdominal tuberculosis was diagnosed in 8.9% of cases by noninvasive comprehensive examination methods, in 18.6% by laparoscopy, and in most cases (57.5%) intraoperatively. In socially dysadapted persons, postmortem abdominal tuberculosis was detected in 15% of cases.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
