[Identification of coagulase-negative Staphylococci. Significance of miniaturized systems]

To evaluate accuracy of API Staph. and Staph. Ident. systems for identification of coagulase-negative Staphylococci, the authors have tested 235 clinical and environmental isolates. The results obtained were compared with those of conventional method of Kloos and Schleifer. API Staph. and Staph. Ident. correctly identified respectively 64 and 53 p. cent of the strains. Diagnosis ability coefficient (Descamps and Véron) are close. It should be necessary to compare identification obtained using analytical profile index with described characteristics of species.
