a
The following database versions of the automated microbial identification systems were used in this study: WalkAway 40 system, version 20.37; MIS, version 3.8; VITEK system, version DSAMSO-R10.3; Replianalyzer system, version 2.11; MicroLog system, version 3.5.
b
S. aureus and B. cereus cultures were not tested with the Biolog databases because these databases were in the process of being revised at the time of the study.
