GASMoC method: a phenol-free technique to detect 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...

Evaluation of a dual-staining method for acid-fast bacilli.

A dual-staining procedure for acid-fast bacilli was found to have poor correlation with the Ziehl-Neelsen and auramine-rhodamine staining techniques.

Comparative morphology of acid-fast bacilli.

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...

Evaluation of a Cold Staining Method for Detecting Acid Fast Bacilli in the Sputum

Tuberculosis is a disease of great importance in developing countries, such as India, where it has caused considerable morbidity and mortality. Sputum smear microscopy is the cornerstone in diagnosis of pulmonary tuberculosis, which is usually done using Ziehl–Neelsen (ZN) method (Vasanthakumari et al., 1986; Gupta et al., 2009; Chandrasekaran et al., 1991). The use of ZN Method in remote areas...
