[Is the a connection between prolonged carriage and clonal hospital-to-hospital clonal spread of multiresistant Pseudomonas aeruginosa of the O12 serotype? Are the specific habits of the hospitals involved the cause?].
Results obtained using our expert computer program (SIR, 12A, Montpellier, France) over the last seven years (1991-1998) suggest that the increased incidence of superficial pus infection or colonization with O12 Pseudomonas aeruginosa, together with the significantly longer carriage duration for this organism as compared to non O12. P. aeruginosa, may contribute to the current endemic clonal spread of O12 P. aeruginosa in a general hospital in Rodez, France, and in neighboring extended-care facilities. This ecological observation may reflect poor compliance with basic hygiene procedures in the Rodez hospital and in neighboring hospitals. The O12 P. aeruginosa clone in the Rodez hospital is indistinguishable from the one that has disseminated throughout Europe, suggesting that the ecological observation and hypothesis described herein may deserve to be investigated in other institutions that are also the site of endemic clonal O12 P. aeruginosa dissemination.

Y a-t-il un lien entre le portage prolongé et la diffusion clonale inter-hospitalière des Pseudomonas aeruginosa multirésistants de sérotype O12? Des habitudes particulières sont-elles en cause dans les hôpitaux concernés?
