Background: Hospital-acquired infections with extensively drug-resistant (XDR) Pseudomonas aeruginosa (PA) have become a worrisome concern because of unfavorable outcomes and limited antimicrobial treatment options. Studies new substances against XDR-PA show very promising results in different infection types, but the data for central nervous system (CNS) are scarce. Case presentation: Here, we...
Multidrug-resistant tuberculosis (MDR-TB) and lately, extensively drug-resistant TB (XDR-TB) are increasing global health concerns. Here, we present the genome sequences of two MDR-TB isolates from Myanmar, one of 27 countries with a high MDR-TB burden, and describe a number of mutations consistent with these being XDR-TB isolates.
BACKGROUND Emergence of extensively drug-resistant tuberculosis (XDR-TB) represents an enormous challenge to Public Health globally. METHODS Progression towards XDR-TB was investigated in Belgium, a country with a typically low TB incidence, by analyzing the magnitude, characteristics, and treatment success of multidrug-resistant tuberculosis (MDR-TB) through a population-based study from 199...
OBJECTIVES Extensively drug-resistant (XDR) tuberculosis (TB) threatens the global control of TB worldwide. Lisbon has a high XDR-TB rate [50% of the multidrug-resistant tuberculosis (MDR-TB)], which is mainly associated with Lisboa family strains. Few studies have addressed the identification of mutations associated with resistance to second-line injectable drugs, and the relative frequency of...
BACKGROUND Multidrug-resistant (MDR) tuberculosis (TB) is more difficult to treat than is drug-susceptible TB. To elucidate the optimal therapy for MDR TB, we assessed the treatment outcomes and prognostic factors for patients with MDR TB. METHODS This study included patients who received an individualized treatment regimen for MDR TB at Samsung Medical Center, a tertiary referral hospital in...
OBJECTIVE Extreme drug-resistant Pseudomonas aeruginosa (XDR-PA) with decreased susceptibility to polymyxin B (PB) has emerged in Singapore, causing infections in immunocompromised hosts. Combination therapy may be the only viable therapeutic option until new antibiotics become available. The objective of this study is to assess the in vitro activity of various antibiotics against local XDR-PA ...
BACKGROUND Drug-resistant tuberculosis (TB) remains extremely difficult to treat because there are often few remaining active medications and limited diagnostic options to detect resistance. Resistance to isoniazid is typically caused by mutations in either katG or the inhA promoter. inhA mutations confer low-level resistance to isoniazid and cross-resistance to ethionamide while katG mutations...
BACKGROUND The prevalence of extensively drug-resistant (XDR) tuberculosis is increasing due to the expanded use of second-line drugs in people with multidrug-resistant (MDR) disease. We prospectively assessed resistance to second-line antituberculosis drugs in eight countries. METHODS From Jan 1, 2005, to Dec 31, 2008, we enrolled consecutive adults with locally confirmed pulmonary MDR tuber...
Kumanan Wilson, Michael Gardam, Christopher McDougall, Amir Attaran, Ross Upshur (This letter appears in response to the May 2007 PLoS Medicine Editorial: “How Is WHO Responding to Global Public Health Threats?” [1]) The travels of a patient with extensively drug-resistant tuberculosis (XDR-TB) from North America to Europe and back have heightened concerns about this growing global disease prob...
The emergence of pre-extensively drug-resistant tuberculosis (pre-XDR-TB) is a threat to TB control programs in developing countries such as Zambia. Studies Zambia have applied molecular techniques understand drug-resistance-associated mutations, circulating lineages and transmission patterns multi-drug-resistant (MDR) Mycobacterium tuberculosis. However, none has reported genotypes mutations a...
