title: [Antibiotypes of bacterial strains isolated from patients at the intensive care units].
abstract: The indiscriminate use of antibiotics in intensive care units has permitted the selection of multiple resistant bacterial strains in the hospital setting. Antibiograms present the sensitivity or resistance of these strains to drugs in current use. In this study, 100 bacterial strains were isolated from patients on medical and surgical ICU wards. The strains were identified by API-20E and sensitivity testing was performed by the E-test procedure. MIC were further analyzed with the WHONET software wich permits the identification of antibiotypes. Acinetobacter anitratus, Pseudomona aeruginosa and Enterobacter cloacae were the most resistant strains. Nine antibiotypes were determinated for A. Anitratus. Predominant strain presented antibiotypes with multiple resistance to ten antibiotics. P. aeruginosa presented 10 antibiotypes, the predominant one being CTX, CRO, CTX. Antibiotype determination allows phenotypic identification or resistance patterns in particular species as well as facilitates follow up and recognition of its epidemiological distribution.
