THE PREPARATION OF CARBOL-FUCHSIN FOR ZIEHL-NEELSEN'S STAIN.

Comparison of variants of carbol-fuchsin solution in Ziehl-Neelsen for detection of acid-fast bacilli.

To evaluate Ziehl-Neelsen (ZN) staining using variants of carbol-fuchsin solution, duplicate smears from 416 samples were stained with ZN, one set with 1% basic fuchsin and the other 0.3%. Another set of duplicate smears from 398 samples were stained with ZN, one with 1% basic fuchsin and the other 0.1%. The coded smears were read and discrepancies resolved. All samples underwent mycobacterial ...

Inefficiency of 0.3% carbol fuchsin in ziehl-neelsen staining for detecting acid-fast bacilli.

We compared the sensitivity and specificity of a modified Ziehl-Neelsen (modified-ZN) staining method for acid-fast bacilli (AFB) with that of the standard Ziehl-Neelsen (standard-ZN) staining method, using culture results with Mycobacterium tuberculosis as the "gold standard." The sensitivity (72%; 101 of 140) of the modified-ZN staining method, which uses 0.3% carbol fuchsin, was significantl...

Comparison of two different strengths of carbol fuchsin in Ziehl-Neelsen staining for detecting acid-fast bacilli.

Evaluation of detection methods for Campylobacter infections among under-fives in Mwanza City, Tanzania

INTRODUCTION Campylobacter species are recognized as a major cause of acute gastroenteritis in humans throughout the world. The diagnosis is mainly based on stool culture. This study was done to evaluate the effectiveness of staining methods (Gram stain using 0.3% carbol fuchsin as counter stain and 1% carbol fuchsin direct stain) versus culture as the gold standard. METHODS A total of 300 ch...
