Demonstration of Mycobacterium Tuberculosis in Sputum and Saliva Smears of Tuberculosis Patients Using Ziehl Neelsen and Flurochrome Staining- A Comparative Study

Comparison 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: ...

Automated 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...

a comparative study of the relationship between self-, peer-, and teacher-assessments in productive skills

تمایل به ارزیابی جایگزین و تعویض آن با آزمون سنتی مداد و کاغذ در سالهای اخیر افزایش یافته است. اکثر زبان آموزان در کلاس های زبان از نمره نهایی که استاد تعیین میکند ناراضی اند. این تحقیق جهت بررسی ارزیابی در کلاس های زبان انگلیسی به هدف رضایتمندی زبان آموزان از نمره هایشان انجام گرفته است که در آن نمرات ارائه شده توسط سه گروه ارزیاب (ارزیابی خود دانشجو، همسالان واستاد) در مهارت های تولید (تکل...

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 ...
