Duration of carriage of multidrug resistant Enterobacterales in discharged hospital and general practice patients and factors associated with clearance.

Objectives: Dutch guidelines recommend contact precautions in patients with multidrug resistant microorganisms cultured during the previous 12 months. To evaluate this policy, duration of carriage of multidrug resistant was assessed among discharged hospital patients and patients attending their general practitioner (GP). Additionally, we assessed factors associated with clearance.

Clinical and molecular characteristics of extended-spectrum-beta-lactamase-producing Escherichia coli causing bacteremia in the Rotterdam Area, Netherlands.

We investigated the clinical and molecular characteristics of bacteremia caused by extended-spectrum-β-lactamase (ESBL)-producing Escherichia coli over a 2-year period (2008 to 2009) in the Rotterdam region (including 1 teaching hospital and 2 community hospitals) of Netherlands. The majority of patients presented with community onset urinary and intra-abdominal infections, with an increase in prevalence during 2009. The majority of E.

Risk factors for bacteremia with uropathogen not cultured from urine in adults with febrile urinary tract infection.

In a prospective study involving 642 patients with febrile urinary tract infection (UTI), we found antimicrobial pretreatment (odds ratio [OR], 3.3), an indwelling urinary catheter (OR, 2.8), and malignancy (OR, 2.

Evaluation of real-time PCR and conventional diagnostic methods for the detection of Clostridium difficile-associated diarrhoea in a prospective multicentre study.

In this prospective multicentre study, an enzyme-linked fluorescent assay (VIDAS CDA2; bioMérieux), an enzyme-linked assay [Premier Toxins A and B (PTAB); Meridian] and an in-house real-time PCR amplifying the tcdB gene were compared with the cell cytotoxicity assay used as the 'gold standard' for diagnosis of Clostridium difficile-associated diarrhoea (CDAD). Faecal samples from patients with a request for C. difficile diagnosis and samples from patients with diarrhoea hospitalized for at least 72 h were collected for 3 consecutive months from four university medical centres in The Netherlands.

Prospective multicenter evaluation of a new immunoassay and real-time PCR for rapid diagnosis of Clostridium difficile-associated diarrhea in hospitalized patients.

In a prospective multicenter study, 367 fecal samples from 300 patients with diarrhea were tested for Clostridium difficile-associated diarrhea (CDAD) with a new immunochromatography assay for toxins A and B (ICTAB), a real-time PCR on the toxin B gene, and the cell cytotoxicity assay. Twenty-three (6.2%) of the 367 fecal samples were positive by the cell cytotoxicity assay.

Bacterial contamination of inhalation chambers: results of a pilot study.

Spacers are used in the treatment of children with asthma. It is advised to clean the spacers regularly. However, cleaning can influence drug delivery.

Coexistence of multiple PCR-ribotype strains of Clostridium difficile in faecal samples limits epidemiological studies.

Clostridium difficile is an important cause of antibiotic-associated diarrhoea. The simultaneous presence of different strains in individual faecal samples has not yet been established, but is important for epidemiological studies. Recurrences of Clostridium difficile-associated diarrhoea (CDAD) are observed in 15-20 % of patients and have been reported as relapses or reinfections with a new strain.
