Figure 2. USA300 strains are relatively resistant to plasma treatment.

Figure 2

Aliquots of either A) 102 or B) 103 CFU of four strains of S. aureus were exposed to plasma for 30, 60, or 180 seconds. An asterisk (*) indicates significantly better killing of the Newman or USA400 (NRS193) strains compared to the two USA300 (LAC and LB) strains at the indicated timepoints and inocula (p < 0.05 by ANOVA).
