A Real-Life Based Evaluation of the Effectiveness of Antibacterial Fabrics in Treating Atopic Dermatitis

Table 2

Comparison of antibacterial activity of conventional AD fabrics subjected to the S. aureus inoculated artificial skin. Results depicted as log 10 reduction factors, means of triplicates with SDs. The zinc-containing samples displayed considerable stronger antibacterial activities after 18 h followed by the silver-containing samples, but only when the samples were prewetted to their individual water absorption capacity. No short-term effect (1 h) of wetted samples on colonized skin was observed.
