Introduction and objectives: Antimicrobial resistant (AMR) is a serious global threat and World Health Organization (WHO) declared AMR is the one among 10 public health threat facing the humanity. Increase in Carbapenem resistant is the major problem which hinders the patient treatment. Various genes are responsible for carbapenem resistant but the gene bla-NDM has the ability to inactivate var...

background and objectives: acinetobacter causes a wide variety of illness in debilitated and hospitalized patients. carbapenem resistance in acinetobacter is an emerging problem and is a cause of concern as many nosocomial infections with acinetobacter are resistant to most other antibiotics. the present study was aimed to study metallo-β-lactamase (mbl) production in acinetobacter species. mat...

AIM Carbapenem-resistant strains have been increasingly reported over the last few years. In this study we used laboratory records to determine the occurrence of carbapenem-resistant strains from hospitalized patients with emphasis on the comparative analysis of the incidence in various health-care settings. MATERIALS AND METHODS From January 2012 to November 2012 and from May 2013 to Novembe...

introduction: the inappropriate use of broad- spectrum antimicrobials in intensive care units (icu) is a universal problem. the main goal of this study was to implement antibiotic stewardship program (abs) concentrated on vancomycin and carbapenems, in pediatric icu (picu) of sheikh hospital. as an accessory purpose we looked for the effect of abs on the rate of antibiotic administration, lengt...

BACKGROUND The purpose of this study was to compare the outcome of carbapenem versus non-carbapenem antimicrobial therapy for pediatric urinary tract infections (UTIs) caused by extended-spectrum β-lactamase (ESBL) producing Enterobacteriaceae. MATERIALS AND METHODS From 2006 to 2011, 42 episodes of UTI caused by ESBL-producing Enterobacteriaceae were diagnosed at Seoul National University Ch...

We explored the mechanism of the development from sensitivity to resistance to carbapenem in Pseudomonas aeruginosa. Two P. aeruginosa strains were collected during treatment with carbapenem. Strain homology was investigated using pulsed-field gel electrophoresis. Porin oprD2 expression was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The minimum inhibitory ...

We evaluated the number of deaths attributable to carbapenem-resistant Enterobacteriaceae by using studies from around the world published before April 9, 2012. Attributable death was defined as the difference in all-cause deaths between patients with carbapenem-resistant infections and those with carbapenem-susceptible infections. Online databases were searched, and data were qualitatively syn...

Many hospital antimicrobial stewardship programs restrict the availability of selected drugs by requiring prior approval. Carbapenems may be among the restricted drugs, but it is unclear if hospitals that restrict availability actually use fewer carbapenems than hospitals that do not restrict use. Nor is it clear if restriction is related to resistance. We evaluated the relationship between car...

The aim of this study was to evaluate the impact of carbapenem-resistant K. pneumoniae bloodstream infections on mortality. During the study period 42, 68 and 120 patients were identified with carbapenem-resistant, extended-spectrum β-lactamase producers (ESBL) and susceptible K. pneumoniae bloodstream infections, respectively. Patients with carbapenem-resistant K. pneumoniae had higher rates o...

The emergence of carbapenem-resistant Pseudomonas aeruginosa in the lung of a patient with cystic fibrosis was evaluated. A single strain of P. aeruginosa persisted during a 3-year study despite antipseudomonal treatment. A stepwise decrease in carbapenem susceptibility leading to resistance was observed in the absence of carbapenem treatment. These data suggest that chronic exposure to unrelat...
