Comparison of Raman spectroscopy and two molecular diagnostic methods for Burkholderia cepacia complex species identification.

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 methods were compared for their diagnostic capacity.

Detection of colon flora in peritoneal drain fluid after colorectal surgery: can RT-PCR play a role in diagnosing anastomotic leakage?

A semi-quantitative Real-Time PCR strategy was developed to identify potential indicator organisms for anastomotic leakage in peritoneal drainage fluid, Escherichia coli and Enterococcus faecalis. The analytical performance of the amplification method was validated with 10 culture-positive and 7 culture-negative peritoneal drain fluid samples, obtained from 9 different patients with a colorectal anastomosis. Real-Time PCR results were fully concordant with the microbiological culture results.

The Bloodgen Project of the European Union, 2003-2009.

The Bloodgen project was funded by the European Commission between 2003 and 2006, and involved academic blood centres, universities, and Progenika Biopharma S.A., a commercial supplier of genotyping platforms that incorporate glass arrays.

Epigenetic regulation identifies RASEF as a tumor-suppressor gene in uveal melanoma.

Purpose: Recently, a segregation study in families with uveal and cutaneous melanoma identified 9q21 as a potential locus harboring a tumor-suppressor gene (TSG). One of the genes in this area, RASEF, was then analyzed as a candidate TSG, but lack of point mutations and copy number changes could not confirm this. In this study, the RASEF gene was investigated for potential mutations and gene silencing by promoter methylation in uveal melanoma.
