We report the genome sequence of Mycobacterium tuberculosis INS-MDR from Peru, a multidrug-resistant tuberculosis (MDR-TB) and Latin American-Mediterranean (LAM) lineage strain. Our analysis showed mutations related to drug resistance in the rpoB (D516V), katG (S315T), kasA (G269S), and pncA (Q10R) genes. Our evidence suggests that INS-MDR may be a clonal expansion related to the African strain...

Contacts of persons infected with multidrug-resistant tuberculosis (MDR TB) have few prophylaxis options. Of 50 contacts of HIV- and MDR TB-positive persons who were treated with moxifloxacin, 30 completed treatment and 3 discontinued treatment because of gastrointestinal symptoms. Moxifloxacin was generally well-tolerated; further research of its efficacy against MDR TB is needed.

We investigated multidrug-resistant (MDR) Mycobacterium tuberculosis strains in Bangui, Central African Republic. We found 39.6% with the same spoligotype and synonymous single nucleotide polymorphism in the mutT1 gene. However, strains had different rpoB mutations responsible for rifampin resistance. MDR strains in Bangui may emerge preferentially from a single, MDR-prone family.

We tested intensive care unit patients for colonization with multidrug-resistant Gram-negative bacilli (MDR GNB) and compared the results with those of concurrent clinical cultures. The sensitivity of the surveillance test for detecting MDR GNB was 58.8% (95% confidence interval, 48.6 to 68.5%). Among 133 patients with positive surveillance tests, 61% had no prior clinical culture with MDR GNB.

The focus of this mini-review is to identify non-toxic compounds isolated from natural sources (plants) that exhibit specific activity against efflux pumps of specific multidrug-resistant (MDR) cancer cell lines, inhibit proliferation of the MDR cancer cell lines and inhibit the activity of overexpressed efflux pumps of the MDR cancer cell line.

Treatment outcome in multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB) is often unsuccessful, but the particular determinants of poor treatment outcome have remained obscure. The present authors therefore analysed treatment effectiveness and predictors of poor treatment outcome in pulmonary MDR-TB and XDR-TB in Estonia, a European country with one of the highest M...

A cryptic multidrug resistance (MDR) system in Stenotrophomonas maltophilia, the expression of which is selectable by tetracycline, is described. Tetracycline resistance was the consequence of active efflux of the antibiotic, and it was associated with resistance to quinolones and chloramphenicol, but not to aminoglycosides or beta-lactam antibiotics. MDR is linked to the expression of an outer...

The history of tuberculosis treatment has observed sequential development of resistance to anti-tuberculosis drugs over the decades. Para amino salicylic acid (PAS) and isoniazid (INH) were introduced to reduce the development of streptomycin (SM) resistance, which heralded the era of combination treatment for tuberculosis [1]. Within 20 years, resistance to both INH and SM was already a challe...

The emergence and spread of multidrug-resistant bacteria (MDR) are major public health issues worldwide. objective this study is to evaluate the microbiological efficacy tigecycline against multi-drug-resistant explore its potential place in clinical practice. A retrospective was carried out over 7 years, from January 2015 December 2021, at Avicenne Military Hospital. Were collected all bacteri...

To the Editor—Multidrug-resistant organisms (MDROs) have recently caused infection outbreaks with increased morbidity and mortality. Colonization of the inanimate hospital environment and intestines may contribute to the increased prevalence of MDROs. To prevent the spread of MDROs in the intensive care unit (ICU), the correlation between colonization of MDROs and the length of patient hospital...
