OBJECTIVES The objectives of this study were to determine the incidence density and the occurrence of horizontal spread of highly resistant gram-negative rods (HR-GNRs) in Dutch hospitals. The factors that influence these outcome measures were also investigated. METHODS All patients with HR-GNRs, as determined by sample testing, who were hospitalized in 1(More)
We compared 2 chromogenic media (Oxoid Brilliance MRSA 2 agar [Thermo Fisher Scientific] and MRSA-ID [bioMérieux]) for the detection of methicillin-resistant Staphylococcus aureus (MRSA) in 1,368 hospital samples. For both media, broth enrichment was essential to obtain satisfactory diagnostic performance. Although with direct cultures only, the diagnostic(More)
The worldwide prevalence of highly resistant Gram-negative rods (HR-GNR) is increasing rapidly. Reliable typing methods are needed to detect and control outbreaks and to monitor the effectiveness of infection control programs in endemic situations. In this study, we investigated the performance of the DiversiLab typing method in comparison with the(More)
The worldwide prevalence of extended-spectrum-beta-lactamase-producing ESBL-producing Enterobacteriaceae (ESBL-E) is increasing, making the need for optimized detection techniques more urgent. In this study we investigated the performance of two ESBL-E screening and two ESBL-E confirmation techniques. In accordance with the Dutch national guidelines(More)
This study evaluated the added value of selective preenrichment for the detection of rectal carriage of extended-spectrum-beta-lactamase-producing Enterobacteriaceae (ESBL-E). ESBL-E rectal carriage was identified in 4.8% of hospitalized patients, and 25.9% of ESBL-E rectal carriers were identified with selective preenrichment only.
Fathers and mothers of Down's syndrome cases show dermal microsymptoms when a large series of parents are compared to the general population. A Walker dermal index score in the overlap range (-2 99 to + 3 '00) is more likely to occur in fathers of age-dependent Down's syndrome cases (mean paternal age 40, range 25 to 54 years) and in Down's syndrome mothers(More)
We assessed the effect of increasing manganese concentrations in test media (0.001 to 1,024 mg/liter) on MICs of tigecycline. For both broth microdilution (BMD) and Etests, this effect was negligible for physiological concentrations, but MICs increased when concentrations exceeded 8 mg/liter. Susceptibility testing should be performed on media with(More)
This paper describes the trends in prevalence of ESBL producing Enterobacteriaceae (ESBL-E) and ESBL genes, measured in five consecutive yearly Point Prevalence Surveys (PPS). All patients present in the hospital and in a day-care clinic (including patients on dialysis) on the day of the survey, were screened for perianal ESBL-E carriage. Perianal swabs(More)
The authors report the case of a patient who developed a Streptococcus Bovis septicemia in the post-operative course of a surgical cure of an incarcerated umbilical hernia. There were no other complaints. A barium enema showed a malignant tumor of the descending colon. There were hepatic metastases. No complementary treatment was undertaken. The patient(More)
Methods In November 2010, a prevalence survey was performed in all patients that were hospitalised in a Dutch teaching hospital by taking rectal swabs. Swabs were placed in a selective broth and incubated overnight. A subculture on a selective agar (EbSA,Cepheid) was performed. Species identification and susceptiblity testing was performed for all isolates(More)
