[Evaluation of a new system for simultaneous identification and antibiograms of enterobacteria from urine].

A new rotor for the ABAC system has been investigated that allows the main enterobacteria of urinary source to be identified (this is performed manually) and simultaneously the relative antibiogram (this is automatically carried out). The precision of this identification has been shown using control strains previously identified by three miniaturized kits: API 20 E, MICRO-ID and ENTEROPLATE. The accuracy of the ten identification tests present in the new "Identibiogramma" rotor has also been shown. Finally, the correspondence has been shown between the antibiogram performed with the automatized method and that with the KirbyBauer method. The data obtained evidence the validity of the new rotor and of the ABAC system.
