Abstract
One thousand two hundred and eighty one clinically suspected untreated patients with pulmonary tuberculosis were studied from an urban tuberculosis clinic in Dhaka. Majority of the 1281 patients (77.6%) were from the age group of 14 to 44 years. Sputum, 106 (8.3%) were found positive for mycobacteria (both by Ziehl-Neelsen smear staining and culture to consider those as confirmed cases of mycobacterial infection. Out of these 106 cases, 101 (95.3%) were identified as M. tuberculosis and the rest 5 (4.7%) as Non-tuberculous Mycobacteria (NTM). Among the 101 M. tuberculosis strains, 30 (29.7%) were resistant to at least one drug; 16 (15.8%); to isoniazid, 11 (10.9%) to rifampicin, 07 (6.9%) to streptomycin, 03 (2.9%) to ethambutol and 04 (3.9%) to pyrazinamide. Multi-drug resistant tuberculosis (MDR-TB) was found in 5 (4.95%) cases. 5 (4.95%) cases were resistant to two drugs and 3 (2.97%) cases to three drugs. Ciprofloxacin was tested against 30 strains of M. tuberculosis; 2 (6.67%) of which were resistant. This is the first report of ciprofloxacin resistant Mycobacterium tuberculosis from Bangladesh. All the 5 strains of NTM tested for said 5 anti-tuberculous drugs, were found resistant to more than one.
