Effects of Cold plasma on Staphylococcus Aureus


Objective: To investigate the effect of cold plasma on Staphylococcus aureus destruction at different treatment times.
Materials and methods: Staphylococcus aureus was cultured on 4 plates of LB Agar medium each at
1.5 × 103 CFU / mL (colony-forming unit per milliliter) and one group was selected as the control group and the other 3 groups were treated with plasma for 5, 7 and 10 minutes. They were incubated for
24 hours at 37 °C. Finally, the number of colonies formed was counted.
Results: It was shown that treatment with cold atmospheric plasma significantly reduced bacterial colonies and in comparison to the control plate with a colony count of 1.5 × 103 CFU/mL treatment with air plasma for 10 minutes decreased the Pseudomonas colony count to zero.
Conclusion: It was observed that the cold atmospheric plasma jet device manufactured in atomic Energy Organization of Iran can significantly kill bacteria in a short time. Increasing the duration of treatment significantly reduces bacterial colonies.
