We evaluated risk factors and treatment outcomes associated with multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB) in Germany in 2004-2006. In 177 (4%) of 4,557 culture-positive TB cases, Mycobacterium tuberculosis isolates were identified as MDR TB; an additional 7 (0.15%) met criteria for XDR TB. Of these 184 patients, 148 (80%) were born in countries of the for...

The worldwide emergence of extensively drug-resistant tuberculosis (XDR TB) and a provisional definition for this form of TB were first reported in November 2005. A more detailed description of these findings and preliminary data from the U.S. National TB Surveillance System (NTSS) were published in 2006. The U.S. data indicated that 74 TB cases reported during 1993-2004 met the case definition...

BACKGROUND . The treatment of extensively drug-resistant tuberculosis (XDR TB) presents a major challenge. Second-line antimycobacterial drugs are less effective, more toxic, and more costly than first-line agents, and XDR TB strains are, by definition, resistant to the most potent second-line options: the injectable agents and fluoroquinolones. We conducted a meta-analysis to assess XDR TB tre...

Fluoroquinolones are rapidly emerging as important drugs in the treatment of tuberculosis (TB) worldwide [1]. In drugsusceptible TB, their use is currently under investigation and, according to the American Thoracic Society/Centers for Disease Control guidelines, fluoroquinolones are indicated only in patients receiving the conventional regimen who present severe adverse reactions [2]. However,...

Extensively drug-resistant (XDR) tuberculosis is defined as disease caused by Mycobacterium tuberculosis with resistance to at least isoniazid and rifampicin, any fluoroquinolone, and at least one of three injectable second-line drugs (amikacin, capreomycin, or kanamycin). The definition has applicable clinical value and has allowed for more uniform surveillance in varied international settings...

Dear Editor, Tuberculosis (TB) is responsible for a large portion of morbidity and mortality worldwide. According to WHO report, tuberculosis is responsible for at least 2 million deaths per year, so 90% of these occurring in developing countries. 1,2 Recently, it has been shown that multidrug-resistance (MDR) and extensively drug-resistant tuberculosis (XDR-TB) are the most important factors c...

Background:Different phylogenetic groups of uropathogenic Escherichia coli are associated with increased virulence and multidrug resistance, highlighting the importance understanding genetic characteristics these isolates for effective treatment prevention UTIs. Genomic analysis was conducted on 100 obtained from multiple hospitals in Baghdad, Iraq, which showed extensive resistance to drugs, i...

TB is an underappreciated public health threat in developed nations. In 2014, an estimated 9.6 million TB cases and 1.5 million deaths occurred worldwide; 3.3% of these cases resulted from multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) strains. These figures underestimate the economic burden associated with MDR-TB and XDR-TB, as the cost of treati...
