Studies on Non-Pathogenic Acid-Fast Bacilli

Comparative morphology of acid-fast bacilli.

Safer staining method for acid fast bacilli.

To develop a method for staining acid fast bacilli which excluded highly toxic phenol from the staining solution. A lipophilic agent, a liquid organic detergent, LOC High Studs, distributed by Amway, was substituted. The acid fast bacilli stained red; nuclei, cytoplasm, and cytoplasmic elements stained blue on a clear background. These results compare very favourably with acid fast bacilli stai...

Relationship between CT Findings of Pulmonary Tuberculosis and Acid-Fast Bacilli Sputum Smears

Background and purpose: Computed tomography (CT) scan is of great help in confirming the diagnosis of tuberculosis (TB) before the sputum test result. The purpose of this study was to investigate the relationship between pulmonary involvement patterns in CT scans of TB patients with positive sputum smears. Materials and methods: This retrospective descriptive-analytical study was conducted usi...

Identifying non-tuberculous mycobacterium lung diseases in acid-fast bacilli positive patients.

We conducted a case-control study by comparing the clinical and radiographic features of acid-fast bacilli positive patients with pulmonary tuberculosis (PTB) to those with non-tuberculous mycobacterium (NTM) lung diseases diagnosed according to American Thoracic Society (ATS) criteria. The occurrence of NTM lung disease was associated with persistence in symptoms after the fifth month of treat...

The Cellular Reactions to Lipoid Fractions from Acid-fast Bacilli

1. A comparative study has been made of the cellular reactions induced by phosphatides from five strains of acid-fast bacilli. Each of these reactions is characterized principally by epithelioid cells and giant cells. 2. The phosphatides are first phagocytized by young connective tissue cells or monocytes. The lipoid is then dispersed into fine particles with the formation of classical epitheli...
