EVALUATION OF DIRECT MICROSCOPY, CULTURE, AND POLYMERASE CHAIN REACTION FOR THE DIAGNOSIS OF TUBERCULOUS MENINGITIS

In view of the importance of early diagnosis of tuberculous meningitis (TBM), the efficiency of the polymerase chain reaction (PCR), one of the most reliable and sensitive DNA-based assays, was compared with conventional methods (acid-fast microscopy and culture) for the detection of M. tuberculosis in cerebrospinal fluid (CSF) specimens from patients suspected of TBM. Of the 29 CSF specim...

Rapid detection of Mycobacterium tuberculosis in sputum by Patho-TB kit in comparison with direct microscopy and culture.

The usefulness of a new rapid diagnostic test (Patho-TB) using antibodies specific to mycobacterial antigens was evaluated for the rapid discrimination between pulmonary tuberculosis (TB) and non-TB pulmonary diseases on sputa. One hundred sputa collected from 79 active TB patients and from 21 patients with non-TB pulmonary diseases (asthma and chronic obstructive pulmonary disease) were enroll...

prevalence of Mycobacterium tuberculosis in patients infected with HIV by microscopical and molecular methods

Background:In some countries, one of the first and most common manifestations of HIV positive patients is tuberculosis (TB). HIV positive people are prone to other infections such as tuberculosis due to immune deficiency and reduced CD4+ cell count. Although increasing access to antiretroviral therapy has led to a reduction in HIV-related opportunistic infections and mortality, the simultaneous...

The Identification of proteins present in culture filtrare of Mycobacterium tuberculosis DT and comparison with human tuberculin proteins by electrophoretic methods

Abstract Background and objectives: Tuberculin is the proteins existed in tuberculosis culture medium which precipitated by trichloroacetic acid (TCA) or ammonium sulfate. Tuberculin is used for diagnosis of Tuberculosis. The aim of this study is to compare the human tuberculin produced by Razi Institute and Mycobacterium tuberculosis Culture Filtrate Protein. Material and Methods: Initially By...
