Evaluation of Sensititre Automated Reading and Incubation System for automated reading of Sensititre broth microdilution susceptibility plates

The Sensititre Automated Reading and Incubation System (ARIS) performs automated reading of Sensititre identification and susceptibility plates. ARIS susceptibility results were compared to manually read results. A total of 212 isolates (3,352 organism-antimicrobial agent combinations) yielded 99.4% essential agreement and categorical error rates of 0.2% minor, 0% major, and 1.0% very major. ARIS yields accurate susceptibility results compared to plates read manually.
