Table 1 Mean log10 reduction CFU overall and CFU of important pathogens on antimicrobial foil compared to control surfaces

From: Long-term antimicrobial effectiveness of a silver-impregnated foil on high-touch hospital surfaces in patient rooms

  N samples Mean (SD) p value Reduction
CFU/cm2 overall
 Control surfaces 202 378 (± 3240)  < 0.001 1.8 log10 CFU
 Antimicrobial foil 201 5.58 (± 24.8)
CFU/cm2 of important pathogens*
 Control surfaces 202 60.61 (± 843.14)  < 0.001 2.6 log10 CFU
 Antimicrobial foil 201 0.14 (± 0.1.59)
  1. Very few gram-negative bacteria were isolated to make meaningful comparisons
  2. * > 90% S. aureus, E. facalis and E. faecium, see Materials and methods
