Evaluation of the R/B and Minitek systems for identification of Enterobacteriaceae

The R/B and Minitek systems for the identification of Enterobacteriaceae were evaluated, and the results were compared with those obtained by conventional methods. Both systems were rapid and allowed correct identification of about 85% of the 294 isolates (23 species) examined. The individual biochemical reactions showed an overall agreement of 92.6% and 93.1% for the R/B and Minitek systems, respectively.
