Although described as a commensal bacterium with low pathogenicity, Cutibacterium acnes involvement has been reported in many clinical entities: infections associated with devices, such as shoulder prosthetic joint infections, osteosynthesis, breast implants or cerebrospinal fluid shunts. Various studies show that C. acnes grows as a biofilm, contributing to its persistence by allowing its escape from the action of the immune system and antibiotics. Our aim was to assess the activity of different active substances (erythromycin, clindamycin, doxycycline and Myrtacine®) on eight different well-characterized C. acnes strains after growth in biofilm mode.Background
