[Non fermentative gram negative bacilli isolated in a hospital laboratory].
OBJECTIVE
To report a prospective study on non fermentative gramnegative bacilli, excluded Pseudomonas aeruginosa, isolated at Dr. Julio C. Perrando Hospital in Resistencia (Argentina). The goal of this study was to know their frequency and antimicrobial susceptibility.


METHODS
For bacterial identifications we used biochemical tests.


RESULTS
The greatest percentages of non fermentative gramnegative bacilli isolates were found in blood samples (25%), respiratory secretions and urine (23.9%). Acinetobacter baumannii (34.7%), Pseudomonas fluorescens/Pseudomonas putida (15.2%), Stenotrophomonas maltophilia (9.7%) and Burkholderia cepacia (8.7%) were the non fermentative gramnegative bacilli species most commonly isolated. Distribution of microorganism strains according to samples and area is also assessed. Antimicrobial sensitivity of most commonly isolated non fermentative gramnegative bacilli strain analyzed.


CONCLUSIONS
We concluded that non fermentative gramnegative bacilli are most frequently present in hospitalized that in outpatients and antibacterial therapy must be provided according to bacteriological information.
