[Application of a computer program for identifying different genera and species of the Enterobacteriaceae family in clinical bacteriology].

Computer programs were developed for the selection of a minimum set of biochemical tests that allow the identification of the species of Enterobacteriaceae with major clinical significance. The system proposed consists of nine conventional biochemical tests, the results of which are interpreted with the help of a numeric code. This selects the most probable species for each result and, when necessary, additional tests can be performed to confirm the identification proposed. The system (SYS9E) was used in the identification of 66 strains of nosocomial origin. The results were compared with those of commercial systems.
