Evaluation of Spectrum-10 system for identification of members of the family Enterobacteriaceae.

摘要

A total of 378 isolates of the family Enterobacteriaceae were tested with conventional biochemical tests and with the Spectrum-10 identification system. Of these, 97.4% were correctly identified to the species level by using the seven-digit profile of Spectrum-10. The preliminary four-digit profile provided the correct species for 61.1% and the correct genus for 79.4% of the strains. Most misidentifications were observed with aberrant biotypes of Citrobacter freundii.
