DNA-based techniques are frequently used to confirm the relatedness of putative outbreak isolates. These techniques often lack the discriminatory power when analyzing closely related microbes such as E. coli. Here the value of Raman spectroscopy as a typing tool for E. coli in a clinical setting was …

The increase of antibiotic resistance worldwide, rising numbers of deaths and costs associated with this, and the fact that hardly any new antimicrobial drugs have been developed during the last decade have increased the interest in Complementary and Alternative Medicine (CAM) therapeutic interventions, …

Staphylococcus aureus is een bacterie die zich vooral in de neus en op de huid bevindt. Wanneer de S. aureus niet meer gevoelig is voor Methicilline, één van de gebruikelijke antibiotica, noemen we de bacterie Methicilline Resistente Staphylococcus aureus (MRSA). Er zijn in het UMC Utrecht twee verschillende …

Purpose With current diagnostic methods, the majority of patients with symptomatic colorectal anastomotic leakage (CAL) is identified approximately 1 week after operation. The aim of this study is to determine whether real-time polymerase chain reaction (RT-PCR) for detection of Escherichia coli and …

Objectives Burkholderia cepacia complex (Bcc) and Pseudomonas aeruginosa strains, colonize the respiratory tract of cyctic fibrosis patients. These strains are phenotypically difficult to discriminate, but differ greatly in their pathogenic potential and species identification is relevant. Here, three …

In 2005, a new sibling species of Aspergillus fumigatus was discovered: Aspergillus lentulus. Both species can cause invasive fungal disease in immune-compromised patients. The species are morphologically very similar. Current techniques for identification are PCR-based or morphology-based. These techniques …

Lectorale rede dr. Willem van Leeuwen uitgesproken op 12 november 2013. Het lectoraat is er voor studenten en docenten om kennis op te doen in Innovatieve Moleculaire Diagnostiek (IMD). De praktijk vindt plaats binnen het LCAB in het Leiden Bio Science Park. In dit kenniscentrum voeren docenten onderzoek …

Five methods were compared to determine the best technique for accurate identification of coagulase-negative staphylococci (CoNS) (n=142 strains). MALDI-TOF MS showed the best results for rapid and accurate CoNS differentiation (correct identity in 99.3%). An alternative to this approach could be Vitek2 …

This report presents the highlights of the 7th European Meeting on Molecular Diagnostics held in Scheveningen, The Hague, The Netherlands, 12-14 October 2011. The areas covered included molecular diagnostics applications in medical microbiology, virology, pathology, hemato-oncology,clinical genetics …
