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...

INTRODUCTION: Non-Fermenting Gram negative bacilli (NFGNB) are emerging multi-drug resistant pathogens causing nosocomial infections. In recent years, carbapenem resistance in NFGNB has increased due to a variety of drug resistance mechanisms, the most common being production of carbapenemases. AIM: To detect carbapenemase and metallo-β-lactamase (MBL) production in NFGNBs by four phenotypic tests and to compare the various phenotypic methods for detection of carbapenemase and MBL production in nosocomial NFGNB isolates...

BACKGROUND: To combat the spread of antimicrobial resistance (AMR), hospitals are advised to screen high-risk patients for carriage of antibiotic-resistant bacteria on admission. This often includes patients previously admitted to hospitals with a high AMR prevalence. However, the ability of such a strategy to identify introductions (and hence prevent onward transmission) is unclear, as it depends on AMR prevalence in each hospital, the number of patients moving between hospitals, and the number of hospitals considered 'high risk'...

Acinetobacter baumannii is a highly versatile nosocomial pathogen. Multidrug resistance among A. baumannii isolates led to the use of colistin, subsequently giving rise to colistin-resistant strains. In this study, the genetic and phenotypic profiles of two colistin-resistant A. baumannii isolates were investigated. Two A. baumannii isolates were obtained from Patient 1 (C071 and C440) and three isolates were obtained from Patient 2 (C080, C314 and C428). Susceptibility profiles were determined by VITEK(®)2 and Etest...

Early detection of patients colonised with carbapenemase-producing Enterobacteriaceae (CPE) is crucial for implementing proper infection control measures. Here we evaluated the biological performance of the Xpert(®) Carba-R v2 (Cepheid) in the daily workflow of a hygiene unit in a country with a low CPE prevalence. Patients repatriated from countries known for high CPE prevalence or contact patients of a known CPE carrier were targeted as being 'high-risk patients' for CPE carriage. Between September 2015 and March 2016, 241 'high-risk patients' for CPE carriage were screened using the Xpert(®) Carba-R v2 and by plating on chromID(®) CARBA Smart medium (bioMérieux) with and without ertapenem-containing enrichment culture for 24 h...
