Resumo(s)
Le seul diagnostic de Ps. aeruginosa n’a qu’une signification mineur en matiére d’épidémiologie. L‘ubiquité de la bactérie, l’absence de critères de virulence et l’existence d’une ecologie du bacille pyocianique dans l’environnement rendent nécessaire l'utilisation das marqueurs epidémiologiques. En effet, nos connaissances actuelles sur les conditions du contrôle et de la préventjon de l’infectjon hospitalière Ps. aeruginosa sont la conséquence de l’utilisation de ces marqueurs en épidémiologie hospitalière.
Les marqueurs utilisés dans notre étude sont les suivants: le sérotype. le lysotype et le pyocinotype
(ou bacteriocinotype).
En ce qui concerne l’application des marqueurs épidémiologiques à l’épidémiologie hospïtaliàre à Lisbonne. deux situations ont été analysées: la prémiêre est celie d’un Centre de Réanimation (malades trachéotomisés) fortement contaminés avec un taux d’infection élevé. malgré une antibiothérapie globale
préventive; I’autre est celle d’un Centre de Récuperation dont le taux de contamination est étudié à travers les résultats des examens microbiologiquesdes urines. effectués pendant une përiode de 13 mois.
The only diagnosis of Ps. aeruqinosa has one «minort» meaning in matters ol epidemiology. The ubiquity of the bacterium, the Iack of virulence criterious and the existence of an ecology of the pyocyaneous bacillus in the environment make the use of epidemiologic markers necessary. In fact our present knowledge about the conditions of control and prevention of hospital infection on Ps. aeruginosa is the consequence of the use of those markers in hospital epidemiology. The markers used in our assay are the following the serotype, the phage type and the pyocin-sensitivity-type. About the application of epidemiological markers on hospital epidemiology in Lisbon two situations have been analysed: firstly the one of Reanimation Center (tracheotomized patients) highly contaminated with a high rate of infection in spite of a global preventive antibiotherapy; secondly the one of a Recuperation Center from which the rate of con mination is studied through the results mirobiological exams of the urines carried out during a period of 13 months.
