Staphylococcus aureus biofilm in atopic dermatitis (AD): In vitro model and in vivo early AD study

Introduction and objectives: Biofilm is one of the most important virulence factors in infectious diseases; biofilm-associated bacteria show an innate resistance to antibiotics and host innate immune defenses. The presence of S. aureus biofilms in AD lesions has been described recently. In AD, biofilm seems to play a role in pruritus, inflammation and in resistance to antimicrobial peptides (PAMs). We used in vitro models to study the role of S. aureus and its biofilm in AD and to evaluate a lipid-replenishing balm specifically formulated for baby and child with atopic skin.
