## Indications for use
The BD PhoenixTM Automated Microbiology System is intended for in vitro quantitative determination of antimicrobial susceptibility by minimal inhibitory concentration (MIC) of most gram-negative aerobic and facultative anaerobic bacteria isolates from pure culture for Enterobacteriaceae and Non-Enterobacteriaceae and most gram-positive bacteria isolates from pure culture belonging to the genera Staphylococcus and Enterococcus. This premarket notification is for the addition of the antimicrobial agent piperacillin-tazobactam at concentrations of 0.5/4-128/4 pig/nml, to gram-negative ID/AST or AST only Phoenix panels. Piperacillin-tazobactam has been shown to be active in vitro against most strains of microorganisms listed below, as described in the FDA-approved package insert for this antimicrobial agent.
