N2 - OBJECTIVE: The purpose of this study was to determine whether the Qoustic Wound Therapy System (Arobella Medical, LLC, Minnetonka, Minnesota) kills planktonic bacterial cells and/or removes bacterial biofilms. DESIGN: The Qoustic Wound Therapy System was evaluated against Pseudomonas aeruginosa, Staphylococcus epidermidis, and Staphylococcus aureus planktonic cells and biofilms in vitro. MAIN RESULTS: P aeruginosa, S epidermidis, and S aureus planktonic cells decreased by a mean of 5.10, 4.99, and 5.22 log10 colony-forming units/mL, respectively, with 4 Qoustic Wound Therapy System treatment minutes. After 10 minutes of treatment, P aeruginosa, S epidermidis, and S aureus biofilms decreased by a mean of 1.34, 1.46, and 1.02 log10 colony-forming units/cm, respectively. CONCLUSION: The Qoustic Wound Therapy System, using the Qoustic Qurette, kills planktonic bacteria and reduces bacterial biofilms in vitro.
