[Nosocomial infections: main causative agents].
BACKGROUND
Nosocomial Infections acquired within a care unit, may be related to various agents (Bacteria, virus, fungi, parasites...). The study purpose is to give relevent data on the main causative agents.
The authors have shown the prevalent role of bacteria, mainly Enterobacteria, Staphylococcus and Pseudomonas; Legionella is also frequently isolated in some countries. Multiresistant Bacteria could be sometimes associated to nosocomial infections and severe infections. Among Nosocomial Virus: VRS, Rotavirus, Hepatitis B and C Viruses, HIV, Influenza Virus are cited. Fungal Agents (Aspergillus, Candida), Plasmodium, Non Conventional Agents (Prions) are also causative agents of Nosocomial Infection.


CONCLUSIONS
The Isolation of contagious Agent in a hospitalized patient is not the only criteria for Nosocomial Infection typing; Rigorous analysis needed to be done for every case.
