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 ...
متن کاملDiagnosis of Tuberculosis: Novel Laboratory Methods
Despite advances in medical sciences in recent years, tuberculosis remains a worldwide health problem. Although there are many laboratory methods to accelerate the diagnosis, a delay in the definitive diagnosis of the disease is still a major clinical problem. Due to the slow growth of the causative agent, (Mycobacterium tuberculosis), isolation, identification, and other clinically important m...

متن کاملComparison of Flurochrome , Ziehl-Neelsen and Tan Thiam Hok Staining Methods for Detection of Mycobacterium tuberculosis in Sputums of Patients with Pulmonary Tuberculosis
Abstract Background and objectives: Direct smear microscopy, because of its simplicity, rapidity, low cost and relatively sensitive is a suitable method to detecting pulmonary tuberculosis. This experiment was aimed at determining the best method for detecting Mycobacterium tuberculosis among three kinds of staining methods: Fluorochrome, Ziehl Neelsen and Tan Thiam Hok . Material and Methods: ...
متن کاملAutomated detection of tuberculosis in Ziehl-Neelsen-stained sputum smears using two one-class classifiers.
Screening for tuberculosis in high-prevalence countries relies on sputum smear microscopy. We present a method for the automated identification of Mycobacterium tuberculosis in images of Ziehl-Neelsen-stained sputum smears obtained using a bright-field microscope. We use two stages of classification. The first comprises a one-class pixel classifier for object segmentation. Geometric transformat...
