The Importance of a Standard in Examination for Tubercle Bacilli

چکیده
In the Report on the Classification of Pl^~ monary Tuberculosis published by the Tuberculosis Association of India (1940), a plea made for the recognition of a definite standard in the examination of sputum for tubercle bacilli, both on the admission and discharge oi patients. The minimum standard suggested for declaring a patient negative is that on discharge no tubercle bacilli should be found in smears on 4 successive days in 3 successive months, but it is recommended that whenever possible concentration tests and cultures should be made oi the sputum and also of the stomach-wasn water.

THE DETECTION OF Mycobacterium tuberculosis BY PCR IN SPUTUM SAMPLES FROM LONG-TERMTREATED LEPROSY PATIENTS: ASSOCIATIONS WITH SKIN TEST RESULTS AND IMMUNOTHERAPY WITH Mycobacterium vaccae
As part of a series of investigations at Baba Baghi Leprosarium in lran, 44 long-treated leprosy patients were selected for our study. Samples of early morning sputum were obtained from each patient, examined by microscopy for acid-fast bacilli (AFB), and cultured for tubercle bacilli. These tests were negative, but the polymerase chain reaction (PCR) for an insertion sequence believed to b...

Dear Editor-in-Chief We read with interest the study by Khazaei et al. (1) in which the authors have nicely concluded that PCR is more sensitive test than Ziehl-Neelsen staining and histo-pathological examination for the diagnosis of tuberculosis (TB). They have rightly pointed to use PCR, selectively, in acidfast bacilli negative paucibacillary forms of TB. However, we intend to highlight few...
