[Catheter-related infections: microbiology].
Coagulase negative staphylococci, Staphylococcus aureus and Pseudomonas sp. are the most frequent microorganisms responsible for catheter-related infections. A relative frequency of microorganisms varies according to the countries, microenvironment and outbreaks of multiresistant bacterias. Infections due to fungi, S. aureus and Pseudomonas sp. are associated with the more severe complications. Recent data suggest that chlorhexidine, either used for cutaneous antisepsis or for catheter impregnation decreases infections due to gram positive cocci. Ecological data should be taken into account when deciding a probabilistic treatment in case of suspicion of catheter-related infection.
