[Bacteriologic profile of bacteremia due to multi-drug resistant bacteria at Charles-Nicolle Hospital of Tunis].
OBJECTIVE
The authors had for aim to evaluate the place of multi-drug resistant bacteria (MDR) in nosocomial bacteremia.


METHODS
A retrospective study was carried out at the Microbiology laboratory of Charles Nicolle hospital of Tunis (2001-2003). One hundred and ninety-five isolated MDR [third generation cephalosporin resistant enterobacteria, methicillin-resistant Staphylococcus aureus (MRSA), Acinetobacter baumannii and Pseudomonas aeruginosa resistant to ceftazidime and imipenem]. An automated system was used to detect bloodstream infections. Microorganism identification was performed by conventional methods and antibiotic susceptibilities were determined by the disk diffusion method.


RESULTS
MDR bacteria were resistant to third generation cephalosporins (29%), A. baumannii (24%), P. aeruginosa (24%), and MRSA (10%). ERC3G were resistant to aminosides and fluorquinolones. A. baumannii and P. aeruginosa had high resistance rates. Associated resistance rates in MRSA were moderate.


CONCLUSIONS
MDR bacteria are of great concern in our hospital. This situation emphasizes the importance to maintain rigorous measures of hygiene as well as adapted antibiotic prescriptions.
