Detection of metallo-β-lactamases-encoding genes among clinical isolates of Pseudomonas aeruginosa in a tertiary care hospital, Kathmandu, Nepal

BMC Research Notes, 2017
Objectives This study was carried out to determine the prevalence of metallo-β-lactamases (MBLs) producing Pseudomonas aeruginosa in imipenem-nonsusceptible isolates and to detect MBL-encoding genes among MBLs-positive isolates.

Protein determinants of dissemination and host specificity of metallo-β-lactamases

Nature Communications, 2019
Metallo-β-lactamases (MBLs) confer resistance to carbapenem antibiotics. Here, López et al. show that the host range of MBLs depends on the efficiency of MBL signal peptide processing and secretion into outer membrane vesicles, which affects bacterial ...

Post-Transplant Fecal Carriage of Antibiotic Resistant and β-Lactamases-Producing Enterobacteriales among Renal Transplant Recipients

Journal of Nepal Health Research Council
Background: The intestinal colonization and transmission of antibiotic-resistant Enterobacteriales to renal transplant recipients may pose a threat to them because they are profoundly immunocompromised and vulnerable to infection.

A general reaction mechanism for carbapenem hydrolysis by mononuclear and binuclear metallo-β-lactamases

Nature Communications, 2017
Carbapenem-resistant bacteria pose a major health threat by expressing metallo-β-lactamases (MβLs), enzymes able to hydrolyse these life-saving drugs. Here the authors use biophysical and computational methods and show that different MβLs share the same ...

Urinary tract infections caused by Gram-negative bacteria in elderly hospitalized patients: Epidemiology, clinical features and outcomes in the era of antimicrobial resistance

Journal of Global Antimicrobial Resistance
Objective: Urinary tract infections (UTI) are among the most common infections in elderly hospitalized patients, often caused by multi-drug resistant (MDR) organisms and characterized by poor clinical outcomes.
