Staphylococcus aureus is one of the most frequent pathogens responsible for biofilm-associated infections (BAI), and the choice of antibiotics to treat these infections remains a challenge for the medical community. In particular, daptomycin has been reported to fail against implant-associated S. aureus infections in clinical practice, while its association with rifampin remains a good candidat...

Stable, homotypic mutants of Chlamydia trachomatis for which MICs of rifampin and rifalazil are elevated were isolated by serial passage at sub-MIC concentrations of these compounds. An alternative approach, in which Chlamydia cells were incubated and subsequently passaged three times, all in the presence of the selective agent at concentrations above the MIC, appeared to be a more effective me...

Tuberculosis (TB) is a global health problem driven by poverty, HIV infection, etc. In Europe, the problem of multidrug resistance (i.e., resistance to at least rifampin and isoniazid) (MR) develops. The cases come essentially from the former U.S.S.R. In Belgium, the incidence of tuberculosis continues to decline to 9.4/100,000 inhabitants in 2008. The percentage of MR germs is 2.8%. The distri...

BACKGROUND Republic of Azerbaijan is considered as an area with high prevalence of multi-drug resistant tuberculosis. Uncontrolled travelling of Azerbaijanis people to Iran is the issue that needs to be considered as an important issue. METHODS This study was conducted on 32 patients with tuberculosis from Baku-Nakhchivan and 48 patients from Iran during 2012 to 2014. Colonies of Mycobacteriu...

To the Editor: In the United States, almost 80% of tuberculosis (TB) cases are diagnosed on the basis of positive culture results for Mycobacterium tuberculosis, and >90% of initial isolates are tested for drug susceptibilities (1,2). Recommended treatment durations are 6–9 months for patients with isoniazidand rifampin-susceptible TB; <18 months for patients with rifampinmonoresistant TB; and,...

Introduction. Multidrug resistance tuberculosis (MDR TB), the combined resistance of Mycobacterium tuberculosis to isoniazid (INH) and rifampin (RFM) is a major public health problem in India as it ranks second among the MDR-TB high burden countries worldwide. WHO recommends RFM resistance as a "surrogate marker" for detecting MDR. FNAC is the most widely used noninvasive investigative techniqu...

We compared the efficiencies of different drug susceptibility testing methods in detecting rifampin (RIF) heteroresistance in Mycobacterium tuberculosis. Our data revealed that the broth dilution method found more resistance than MGIT did (P=0.046) for the low-resistance group. Similarly, the broth dilution method was more sensitive in detecting RIF heteroresistance in subpopulations with low g...
