Surviving bacteria after plasma treatment of 10 μl MRSA strain LUH14616 (a) in dry CEM (n=6 in duplicate), (b) in wet CEM (n=5 in duplicate) or (c) on human dermis (n=3–6 in duplicate). All samples were placed on chicken meat; human skin was placed around them. Distance between plasma pad and tissue was increased by adding layers of skin surrounding the CEM. Mean values and standard deviation are shown. * Significant difference compared to untreated control samples (0 s), p<0.05 (MWU).
