Antibiofilm activity of Cutibacterium acnes cell-free conditioned media against Staphylococcus spp.

ABSTRACT: Staphylococcus spp. and Cutibacterium acnes are members of the skin microbiome but can also act as pathogens. Particularly, Staphylococcus species are known to cause medical devices-associated infections, and biofilm production is one of their main virulence factors. Biofilms allow bacteria to adhere and persist on surfaces, protecting them from antimicrobials and host defenses. Since both bacteria are found in the human skin, potentially competing for niches, we aimed to investigate if C. acnes produces molecules that affect Staphylococcus spp. biofilm formation and dispersal. Thus, we evaluated the impact of C. acnes cell-free conditioned media (CFCM) on S. aureus, S. epidermidis, S. hominis, and S. lugdunensis biofilm formation. S. lugdunensis and S. hominis biofilm formation was signif
