Validation of a rapid method for detection of M. tuberculosis resistance to isoniazid and rifampin in Lima, Peru.

Detection of Isoniazid and Rifampin Resistant Strain of Mycobacterium Tuberculosis Isolated from patients in Golestan province (North of Iran)

Abstract Background and objectives: With almost nine million new cases each year, tuberculosis is still one of the most Life-threatening diseases in the World. Distribution of drug resistant strains of M.tuberculosis has a lot of importance. This research was carried out to determine the frequency of drug resistance of M. tuberculosis in strains isolated in Golestan province. Material and...

تشخیص موتاسیون در کدون 315 ژن katG، مارکر مقاومت به ایزونیازید در سوش‌های مایکوباکتریوم توبرکولوزیس‌ جدا شده از بیماران اصفهان و تهران با روش PCR-RFLP

Background and Objective: Drug resistance to tuberculosis is continuously increasing and is a significant threat to tuberculosis control programs because afew effective drugs are present against Mycobacterium tuberculosis. Although isoniazid (INH) is the most effective drug against tuberculosis, resistance to this drug also develops readily. Mutations in katG, specially the Ser315Thr substituti...

Minor Contribution of inhA-15 Mutations to the Rapid Detection of Isoniazid Resistance in Mycobacterium Tuberculosis Isolates

Targeted Drug-Resistance Testing Strategy for Multidrug-Resistant Tuberculosis Detection, Lima, Peru, 2005–2008

The Peruvian National Tuberculosis Control Program issued guidelines in 2006 specifying criteria for culture and drug-susceptibility testing (DST), including district-level rapid DST. All patients referred for culture and DST in 2 districts of Lima, Peru, during January 2005-November 2008 were monitored prospectively. Of 1,846 patients, 1,241 (67.2%) had complete DST results for isoniazid and r...

Investigation of the rpoB Mutations Causing Rifampin Resistance by Rapid Screening in Mycobacterium Tuberculosis in North-East of Iran

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...
