[ XXXX susceptibility in @entity328 strains isolated at Puerto Montt Hospital between 1995 and 2003].

@entity1 @entity114 @entity2260 @entity328
BACKGROUND: The emergence and dissemination of resistance to @entity114 among @entity328 changed the approach to empiric antimicrobial therapy. AIM: To evaluate the in vitro susceptibility to @entity114 in all @entity2260 strains isolated in Puerto Montt Hospital between 1995 and 2003. MATERIAL AND METHODS: We revised all Microbiology Laboratory files of this period. Identification and antimicrobial susceptibility study methods for @entity2260 did not change during the study period. RESULTS: Six hundred eighteen @entity2260 strains were identified. Of these, 66% came from adults and 48% from invasive diseases. Only 1.9% of strains were @entity114 resistant and 7.6% had intermediate sensibility. Strains isolated from @entity1 and those isolated from non sterile sources had non significantly higher resistance levels. The susceptibility did not change along the years of the study. CONCLUSIONS: Among @entity2260 strains isolated at Puerto Montt Hospital, the prevalence of @entity114 resistance is low.
