Serum in vivo and in vitro activity of single dose of ertapenem in surgical obese patients for prevention of SSIs.

Background: Despite progress made in the control of post-operative infections, the incidence of surgical site infections (SSIs) is still high. An improper perioperative antibiotic use can expose patients to the risk of resistant microorganisms, and, in surgical obese patients, the drug dosage and infusion time are critical points. The aim of our study was to evaluate the effectiveness of ertapenem in the prophylaxis of SSIs in obese patients undergoing general or bariatric surgery.

Rapid identification of Burkholderia cepacia complex species recovered from cystic fibrosis patients using matrix-assisted laser desorption ionization time-of-flight mass spectrometry.

The aim of this study was to establish the identification ability of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) for bacteria of Burkholderia cepacia complex (Bcc) and to compare these results with those obtained by a molecular method (PCR-RFLP). A total of 57 isolates was used in the study. Isolates were collected from 31 patients attending the Regional Cystic Fibrosis Unit from January 2001 to December 2005.
