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-...
in recent years, tuberculosis has had a significant rise, caused mainly by the epidemic of acquired immunodeficiency syndrome. the anorectal tuberculosis is a very rare presentation. herein, we presented a 67-year-old man who has had renal transplantation and presented with hematochezia and painful defecation since 6 months before. biopsy was taken from the lower rectal ulcerated lesion. histop...
Background and Objective: Tuberculosis is still a major health problem, involving about 1/3 of the world´s population. Diagnosis is difficult when we only use Ziehl-Neelson staining. Many cases may be missed. A more rapid and sensitive diagnostic method is necessary. PCR may be helpful. The aim of this study was to compare PCR, Zieh-Neelsen staining and histopathologic findings in diagnosis of ...

Introduction: Mycobacterium tuberculosis is the second most infectious cause of death in adults globally and major health trouble Nepal. The diagnosis pulmonary mainly carried by acid-fast bacilli smear microscopy, culture on Lowenstein–Jensen media, GeneXpert MTB/RIF assay. This study aimed to evaluate Acid-Fast Bacilli stain used for tuberculosis.

The goal of this study was to evaluate the effect of the specimen-processing method that uses the detergent C18-carboxypropylbetaine (CB-18) on the sensitivity of acid-fast bacillus (AFB) staining. Vietnamese immigrants with abnormal chest radiographs provided up to three sputum specimens, which were examined for acid-fast bacilli by use of direct auramine and Ziehl-Neelsen staining. The remain...
AIMS To evaluate a safe sputum processing method for detection of tuberculosis in developing countries. METHODS A sample processing method was developed in which acid fast bacilli were killed with 1% sodium hypochlorite and concentrated by flotation on a layer of xylene before staining by the Ziehl Neelsen or auramine O methods. RESULTS Best results were obtained by auramine O staining afte...
