Carbapenemase-producing Enterobacteriaceae (CPE) strains have been increasingly reported in Belgium. We aimed to determine the proportion of CPE among Enterobacteriaceae isolated from hospitalised patients and community outpatients in Belgium in 2015. For the hospitalised patients, the results were compared to a previous similar survey performed in the same hospitals in 2012. Twenty-four hospital-based and 10 private laboratories collected prospectively 200 non-duplicated Enterobacteriaceae isolates from clinical specimens...

Resistance to carbapenem antibiotics through the production of New Delhi Metallo-β-lactamase-1 (NDM-1) constitutes an emerging challenge in the treatment of bacterial infections. To monitor possible source of spread of these organisms in Dhaka, Bangladesh, we conducted comparative analysis of waste water samples from hospital adjacent areas (HAR) and from community areas (COM) as well as public tap water samples for the occurrence and characteristics of NDM-1 producing bacteria. Of 72 HAR samples tested 51 (71%) were positive for NDM-1-producing bacteria as evidenced by phenotypic tests and the presence of blaNDM-1 gene, compared to 5 of 41 (12...

Antibiotics are useful for improving the living conditions of livestock. However, residual antibiotics induce several human diseases such as food-borne illness and infection of carbapenem-resistant Enterobacteriaceae (CRE). In this study, the identification of a benzylpenicillin-specific aptamer was selected by rGO-SELEX (reduced Graphene Oxide-Systematic Evolution of Ligands by EXponential enrichment). A random ssDNA library was incubated with rGO for adsorption and eluted with benzylpenicillin. As a result of the selection process, a DNA aptamer was found that specifically bound to benzylpenicillin with high binding affinity, Kd = 383...

INTRODUCTION: Members of family Enterobacteriaceae are the most common Gram-negative bacteria isolated from clinical samples. Those Enterobacteriaceae which have acquired resistance to all β-lactams antibiotics including the carbapenems are considered as Carbapenem Resistant Enterobacteriaceae (CRE). These CRE isolates are often resistant to most other classes of antimicrobials as well, making their treatment a great challenge. Tigecycline is one of the last resort antimicrobials against such multidrug resistant bacteria...

The spread of mcr-1-encoding plasmids into carbapenem-resistant Enterobacteriaceae raises concerns about the emergence of untreatable bacteria. We report the acquisition of mcr-1 in a carbapenem- resistant E. coli after a 3-week course of colistin in a patient repatriated to France from Portugal. Whole-genome sequencing revealed that the KPC-producing E. coli strain acquired two plasmids, an IncL OXA-48-encoding plasmid and an IncX4 mcr-1-encoding plasmid. This is the first report of mcr-1 in carbapenemase-encoding bacteria in France...

Imipenem is active against extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) but favours the intestinal emergence of resistance. The effects of imipenem on intestinal microbiota have been studied using culture-based techniques. In this study, the effects were investigated in patients using culture and metagenomic techniques. Seventeen hospitalised adults receiving imipenem were included in a multicentre study (NCT01703299, http://www.clinicaltrials.gov). Most patients had a history of antibiotic use and/or hospitalisation...

A rapid and accurate diagnosis of the species and antibiotic resistance of bacteria in septic blood is vital to increase survival rates of patients with bloodstream infections, particularly those with carbapenem-resistant enterobacteriaceae (CRE) infections. The extremely low levels in blood (1 to 100CFU/ml) make rapid diagnosis difficult. In this study, very low concentrations of bacteria (6 to 200CFU/ml) were separated from 7ml of whole blood using rapid sedimentation in a spinning hollow disk that separated plasma from red and white cells, leaving most of the bacteria suspended in the plasma...

INTRODUCTION: Cholecystectomy is a common surgical procedure. The presence of common bile duct stones complicates treatment, often requiring a second procedure for stone retrieval. For such patients, endoscopic retrograde cholangiopancreatography (ERCP) provides adequate therapy, and can be performed before, after, or at the same time as cholecystectomy. In 2013, duodenoscopes were implicated by the Centers for Disease Control and Prevention in transmission of carbapenem-resistant Enterobacteriaceae...

Ceftazidime-avibactam is a novel cephalosporin-beta-lactamase inhibitor combination that is active against many carbapenem-resistant Enterobacteriaceae (CRE). We describe a retrospective chart review whereby 60 patients received ceftazidime-avibactam for a CRE infection. In hospital mortality was 32%, 53% of patients had microbiological cure, and 65% had clinical success. In this severely ill population with CRE infections, ceftazidime-avibactam was an appropriate option.
