[Nosocomial bacteria: profiles of resistance]. / Les bactéries nosocomiales: profils de résistance.

ABSTRACT

Nosocomial infections may be parasitic, mycosal or viral, but bacterial infections are more frequent. They are transmitted by hands or by oral route. This paper describes the main bacteria responsive of nosocomial infections, dominated by Staphylococcus, enterobacteria and Pseudomonas aeruginosa. The author relates natural and savage profiles of these bacterias, characterized by multiresistance due to large use of antibiotics. Knowledge of natural resistance and verification of aquired resistance permit to well lead probabilist antibiotherapy.
