background and objectives: sputum smear staining for acid-fast bacilli is initial approach to the diagnosis of pulmonary tuberculosis (ptb) but more than 50% of cases are sputum smear-negative. this study was aimed to investigate the diagnostic value of fiberoptic bronchoscopy (fob) guided bronchoalveolar lavage (bal) in patients suspected to have tuberculosis. methods: this prospective cross-s...

we investigated the use of dna amplification by polymerase chain reaction (per) for detection of mycobacterium tuberculosis in 300 patients who were suspected of having pulmonary tuberculosis and compared the results with culture results which were performed in parallel with pcr. two-thirds of each sample was processed for smear and culture by standard methods and one-third was prepared for dna...

The bacterium was resistant to cotrimoxazole, ...
