A Comparative Study of Auramine Staining Using Light Emitting Diode (LED) Fluorescent Microscopy with Ziehl-Neelsen Staining for Detection of Acid Fast Bacilli in Sputum in a Tertiary Care Hospital, Karimnagar

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...

A Comparison of Ziehl-Neelsen Staining and Fluorescent Microscopy for Diagnosis of Pulmonary Tuberculosis

According to WHO one third of the world population have tuberculosis. The present study was undertaken to compare the efficacy of flurochrome(FI) stain with conventional Z-N stain in the diagnosis of pulmonary & extrapulmonary tuberculosis. 388 cases of suspected pulmonary tuberculosis were included in the study. All samples were screen for Acid Fast Bacilli (AFB) by Z-N & Fluorescent staining ...

The CyScope® fluorescence microscope, a reliable tool for tuberculosis diagnosis in resource-limited settings.

Poor laboratory equipment and few human resources have made it difficult to implement microscopic diagnosis of pulmonary tuberculosis (TB) on a large scale basis worldwide. Three hundred sputum samples from patients in Cameroon were studied by using the CyScope®, a new light-emitting, diode-based, fluorescence microscope, to compare auramine-rhodamine fluorescence with the conventional Ziehl-Ne...

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

مقایسه ارزش تشخیصی اسمیر خلط به دو روش میکروسکوپی در بیماران مشکوک به سل ریوی با و بدون استفاده ازهیپوکلریت سدیم

Background and purpose: Direct smear microscopy is the most common method of detecting tuberculosis with 70% sensitivity in best conditions, therefore, researches have always focused on improving the sensitivity of sputum smear. This study aimed at comparing the diagnostic value of sputum smear using light microscopy and fluorescence microscopy without sodium hypochlorite in patients with suspe...
