Background Multidrug resistance (MDR) TB is on the rise globally and is associated with significant morbidity and mortality. Conventional culture based drug susceptibility testing (DST) for TB drugs is time consuming, leading to diagnostic delays contributing to higher TB morbidity and mortality and exacerbation of ongoing transmission. Moreover most of the NTM(Non tuberculous mycobacteria) tha...
The goal of this study was to evaluate the prevalence of first-line anti-tuberculosis drug resistance and risk factors associated with multidrug-resistant tuberculosis (MDR TB) among young soldiers in the Korean military, which has a strict tuberculosis control program. All patients with culture-confirmed pulmonary tuberculosis during their service at the Armed Forces Capital Hospital from Janu...
Introduction: Aloe vera has anti-bacterial ability against Gram-positive and Gram-negative bacteria; however, study, especially in multidrug resistant strain of Mycobacterium tuberculosis, not been evaluated yet. This study aims to determine the potential as an antituberculosis drug-resistant strains tuberculosis. Method: Stages research include production ethanol extract vera, then testing phy...
Nitrate reductase assay using sodium nitrate for rapid detection of multidrug resistant tuberculosis
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 is cheaper than KNO3 and has no restriction on use which facilitates the implementation of NRA to detect MDR-TB.
Background and Objectives: The incidence of rifampin-resistant strains of Mycobacterium tuberculosis has attracted more attention than the tuberculosis infection due to laborious treatment and control. Recognizing the Mycobacterium tuberculosis genotypes involving in drug resistance via multiplex PCR, a simple and rapid genotyping method, is an emergency for better tre...
The emergence and spread of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB) has raised public health concern about global control of TB. To estimate the transmission dynamics of MDR and XDR TB, we conducted a DNA fingerprinting analysis of 55 MDR/XDR Mycobacterium tuberculosis strains isolated from TB patients throughout Japan in 2002. Twenty-one (38%) of the st...
Mycobacterium tuberculosis strains that are resistant to an increasing number of second-line drugs used to treat multidrug-resistant tuberculosis (MDR TB) are becoming a threat to public health worldwide. We surveyed the Network of Supranational Reference Laboratories for M. tuberculosis isolates that were resistant to second-line anti-TB drugs during 2000-2004. We defined extensively drug-resi...
A promising modified sugar molecule was identified which was active against multidrug-resistant (MDR) strains of Mycobacterium tuberculosis, suggesting involvement of a new target. The compound was demonstrated to be bactericidal, inhibited the growth of M. tuberculosis in mice, and targeted alpha-mannosidase as a competitive inhibitor with a Ki value of 353.9 μM.
Although drug susceptible tuberculosis (TB) is a curable disease, spread of rifampicin-resistant TB, including multidrug-resistant (MDR)and extensively drug-resistant (XDR)-TB, is a threat to disease control worldwide [1], in particular in Eastern Europe [2]. XpertMTB/RIF (Xpert; Cepheid Inc., Sunnyvale, CA, USA) is an accurate [3] and affordable [4] automated PCR-based assay that detects DNA o...
OBJECTIVE This study represents an early attempt to determine the diversity of Mycobacterium tuberculosis in Egypt, particularly of drug-resistant strains. METHODS We characterized 45 Mycobacterium tuberculosis complex isolates from sputum samples of Egyptian patients with pulmonary tuberculosis, in order to establish a database of strain types and antimicrobial susceptibility patterns. RES...
