BACKGROUND Multidrug-resistant (MDR) tuberculosis is a potential threat to tuberculosis elimination, but the extent of MDR tuberculosis disease in the USA that is attributable to transmission within the country is unknown. We assessed transmission of MDR tuberculosis and potential contributing factors in the USA. METHODS In a cross-sectional study, clinical, demographic, epidemiological, and ...
BACKGROUND Multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis are emerging worldwide. The Green Light Committee initiative supported programmatic management of drug-resistant tuberculosis in 90 countries. We used estimates from the Preserving Effective TB Treatment Study to predict MDR and XDR tuberculosis trends in four countries with a high burden of MDR tuberculosis:...
BACKGROUND The prospects for global tuberculosis control in the near future will be determined by the effectiveness of the response of countries to their burden of multidrug-resistant (MDR; resistance to, at least, isoniazid and rifampicin) tuberculosis. During the 2009 World Health Assembly, countries committed to achieve universal access to MDR-tuberculosis care by 2015. We assessed the progr...
Children exposed to multidrug-resistant (MDR) Mycobacterium tuberculosis are at risk of developing MDR tuberculosis. Where treatment is available, it is lengthy, expensive, and associated with poor adherence and notable morbidity and mortality. Preventive treatment effectively lowers the risk of disease progression for contacts of individuals with drug-susceptible tuberculosis, but this strateg...
Multidrug resistant tuberculosis (MDR-TB) has been an area of growing concern and is posing a threat to the control of tuberculosis (TB). The exact magnitude of problem of resistance to anti-tuberculosis drugs worldwide was not known till the 1994-97 global project on anti-tuberculosis drug resistance surveillance initiated by the World Health Organization (WHO) and International Union Against ...
Introduction: Infections by multidrug resistant Mycobacterium tuberculosis (MDR-TB) is a major public health challenge. Secretion of proteins by M. tuberculosis plays an important role in the pathogenesis of the bacterium. We compared the protein profiles of susceptible M. tuberculosis and MDR-TB isolates using proteomic analyses, namely two dimensional gel electrophoresis (2DE) and mass spectr...
BACKGROUND It is difficult to determine whether early tuberculosis treatment is effective in reducing the infectiousness of patients' sputum, because culture takes weeks and conventional acid-fast sputum microscopy and molecular tests cannot differentiate live from dead tuberculosis. METHODS To assess treatment response, sputum samples (n=124) from unselected patients (n=35) with sputum micro...
New and better drugs are needed for tuberculosis (TB), particularly for the multi-drug resistant (MDR) disease. However, the highly infectious nature of MDR Mycobacterium tuberculosis restricts its use for large scale screening of probable drug candidates. We have evaluated the potential of a screen based on a 'fast grower' mycobacterium to shortlist compounds which could be active against MDR ...
We investigated the linezolid susceptibility of Mycobacterium tuberculosis strains isolated from a tertiary care hospital in Izmir. A total of 67 M. tuberculosis strains (33 multidrug-resistant [MDR] and 34 non-MDR) were isolated and identified by the Tuberculosis Laboratory, Department of Microbiology and Clinical Microbiology, Faculty of Medicine, Ege University. The activity of linezolid was...
TO THE EDITOR—How does the global community gain more traction in an effort to combat multidrug-resistant (MDR) tuberculosis globally? We have considered whether it would be helpful to address MDR tuberculosis as a separate epidemic. We introduced the idea because the dominant strategy globally for the past 2 decades has been based on the premise that MDR tuberculosis could be controlled by str...
