BACKGROUND To control multidrug resistant tuberculosis (MDR-TB), the drug susceptibility profile is needed to guide therapy. Classical drug susceptibility testing (DST) may take up to 2 to 4 months. The GenoType MTBDRplus test is a commercially available line-probe assay that rapidly detects Mycobacterium tuberculosis (MTB) complex, as well as the most common mutations associated with rifampin ...

Drug resistance which is at present the main impendence to global tuberculosis (TB) control and drug- resistant (DR) activity of Mycobacterium in various strains have become major challenge worldwide. Nowadays, many researchers use different antibiotics for treatment DR-TB are often not well tolerated adequately efficient. A large group study from research published time described a regimen mul...

Thirty-seven multidrug-resistant and 13 pan-susceptible isolates of Mycobacterium tuberculosis were analysed for the diversity of genotypes associated with known drug-resistance mechanisms. The isolates were obtained from patients attending a university tuberculosis clinic in Monterrey, Mexico. A total of 25 IS6110-RFLP patterns were obtained from the multidrug-resistant tuberculosis (MDR-TB) i...

BACKGROUND & OBJECTIVES The emergence of drug resistance tuberculosis (TB) is a significant challenge for TB control and prevention programmes, and the major problem is multidrug resistant tuberculosis (MDR-TB). The present study was carried out to determine the frequency of drug resistant Mycobacterium tuberculosis isolates among newly and retreated TB lymphadenitis patients and risk factors f...

Drug resistance tuberculosis (TB) and the emergence of multidrug resistant (MDR) isolates are significant concerns regarding TB control programs in several countries. This study was undertaken to evaluate the drug sensitivity of Mycobacterium tuberculosis and to assess its association with strains and lineages of M. tuberculosis. A total of 279 M. tuberculosis strains isolated from Central Ethi...

An immunocompetent patient was dually infected with a resistant and a multidrug-resistant strain of Mycobacterium tuberculosis (TB). The multidrug-resistant strain, which belongs to the W- strain/Beijing family, was first isolated after 3 months of therapy. Inappropriate treatment led to further drug resistance and unsuccessful therapy. Thus, additional infections with resistant M. tuberculosis...

BACKGROUND Current guidelines for treatment of multidrug-resistant tuberculosis (MDR-TB) are largely based on expert opinion and observational data. Fluoroquinolones remain an essential part of MDR-TB treatment, but the optimal dose of fluoroquinolones as part of the regimen has not been defined. METHODS/DESIGN We designed a randomized, blinded, phase II trial in MDR-TB patients comparing acr...

BACKGROUND Tuberculosis (TB) is a widespread infectious disease. Today, TB has created a public health crisis in the world. Genotyping of Mycobacterium tuberculosis isolates is useful for surveying the dynamics of TB infection, identifying new outbreaks, and preventing the disease. Different molecular methods for clustering of M. tuberculosis isolates have been used. OBJECTIVES During a one y...

This case series describes the medical management of four pregnant women with active multidrug-resistant tuberculosis. None of the four patients were infected with human immunodeficiency virus. Three patients had disease due to multidrug-resistant Mycobacterium tuberculosis, and one had disease due to multidrug-resistant Mycobacterium bovis. Only one patient (patient 3) began retreatment during...
