Triage strategy used in this study.

<p>High-throughput activity screening used robotic spotting and an optical scanner for the determination of the zones of inhibition. MIC testing provided specific activity values for the determination of the potency. Stability testing performed using biologically-relevant substrates. <i>In vivo</i> efficacy performed in the Golden Syrian hamster model of CDAD.
