Extrapulmonary tuberculosis: a potential source of laboratory-acquired infection.

Tuberculous myositis: an unusual presentation of extrapulmonary tuberculosis.

The prevalence of Mycobacterium tuberculosis infection in Taiwan has increased in recent decades. Extrapulmonary infection accounts for 40% of all tuberculosis cases. Here we report a seven-year-old girl with culture-proven tuberculous myositis manifested as progressive enlargement of chest wall mass. No congenital or acquired immune deficiency could be traced at presentation. After surgical ex...

Mycobacterium tuberculosis Dominance over Nontuberculous Mycobacteria Irrespective of Immune Status: An Indian Scenario

Introduction: In HIV-associated tuberculosis cases, identifying nontuberculous Mycobacteria (NTM) from clinical samples has become essential regarding patients’ treatment and prognosis. This study aims to determine the prevalence of different Mycobacteria species from immunocompromised and immunocompetent patients with suspected tuberculosis attending a tertiary care hospital in Kolkata, India....

Epidemiology of extrapulmonary tuberculosis. A comparative analysis with pre-AIDS era.

To study the changes in the epidemiology of extrapulmonary tuberculosis in Tennessee, we compared the 454 cases of extrapulmonary tuberculosis reported between 1977 and 1981 with 356 cases encountered between 1982 and 1986. The data were analyzed by age, sex, race and site of the disease which were compared with the national statistics during the periods. We observed that 11.3 percent of the to...

Extrapulmonary Tuberculosis Masquerading Neoplasm: A Series of Seven Cases Diagnosed by FNAC

pncA Mutations in the Specimens from Extrapulmonary Tuberculosis

BACKGROUND Pyrazinamide (PZA) is an effective antitubercular drug that becomes toxic to Mycobacterium tuberculosis when converted to pyrazinoic acid by pyrazinamidase (PZase), encoded by mycobacterial pncA. A strong association was noted between the loss of PZase activity and PZA resistance. The causative organisms in extrapulmonary tuberculosis are rarely cultured and isolated. To detect pncA ...
