A major threat to tuberculosis (TB) control programs is the emergence of drug resistant Mycobacterium tuberculosis strains that cause TB that cannot be cured by standard anti-TB drug regimens. Because few data exist on ...

Tuberculosis remains as a serious infection disease of worldwide distribution, with high morbidity and mortality, mainly in low socio-economic condition countries. The state of emergency of tuberculosis caused by the ...

This cross sectional study aimed at the determination of the prevalence of the knowledge about the adherence to the tuberculosis treatment that clients suffering of pulmonary tuberculosis and their families have concerning ...

Drug resistant tuberculosis continues to increase and new approaches for its treatment are necessary. The identification of M. tuberculosis clinical isolates presenting efflux as part of their resistant phenotype has a ...

Introduction: Reports of Mycobacterium tuberculosis resistant to multiple drugs are increasing globally and laboratories are becoming increasingly aware of the need for drug susceptibility testing. In recent years, due ...

RDRio is a novel Mycobacterium tuberculosis lineage of the Latin American– Mediterranean (LAM) family. LAM has been found worldwide but is more predominant in South America. The aim of this study was to assess the presence ...

Aspergillus is a phagocyte opportunistic fungus that causes aspergillosis, an unusual disease in patients with AIDS. Six cases of fungal ball in patients with AIDS are reported here. In this group, all patients had hemoptysis ...

A series of twenty-three N-acylhydrazones derived from isoniazid (INH 1-23) have been evaluated for their in vitro antibacterial activity against INH- susceptible strain of M. tuberculosis (RG500) and three INH-resistant ...

Tuberculosis remains one of the major causes of mortality worldwide. The early detection of new cases is an important goal in the program of tuberculosis control. Several methodologies for rapid and accurate laboratorial ...

Mycobacterium bovis is the main causative agent of animal tuberculosis (TB) and it may cause TB in humans. Molecular typing of M. bovis isolates provides precise epidemiological data on issues of inter- or intra-herd ...

Objectives: The purpose of this study was to develop the nitrate reductase assay (NRA) for the rapid detection of pyrazinamide resistance in Mycobacterium tuberculosis using nicotinamide resistance as a marker of ...

We validated the nitrate reductase assay (NRA) for the detection of multidrug-resistant Mycobacterium tuberculosis (MDR-TB) using sodium nitrate (NaNO3) in replacement of potassium nitrate (KNO3) as nitrate source. NaNO3 ...

High speed countercurrent chromatography (HSCCC) was used to isolate the dammarane type triterpene shoreic acid from the dichloromethane extract of leaves of Cabralea canjerana, which showed activity against Mycobacterium ...

Backgound and Objectives: This study is justified by the high TB prevalence in prisons, which constitutes a public health problem and aims to estimate the prevalence of active tuberculosis (TB) and determine the variables ...

ABSTRACT Introduction: The World Health Organization endorses the BACTEC Mycobacterial Growth Indicator Tube (MGIT)™ system as a rapid, sensitive, and specifi c method to diagnostic of tuberculosis. Here, we compared the ...
