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 fluroescent stainwith Z-N stain in the diagnosis of pulmonary. 793 cases of suspected pulmonarytuberculosis were included in the study. All samples were screen for Acid FastBacilli (AFB) by Z-N & Fluorescent staining methods. Positive samplesdetected by fluorescent stain were 121(15.22%) when compared to Zn stain71(8.95%). Conclusion Compared to Z-N stain(8.95%). flurochrome staining was found to be more efficient (15.22%) in AFBdetection of AFB from cases of Pulmonary Tuberculosis.
