Paracetamol modulates biofilm formation in Staphylococcus aureus clonal complex 8 strains

Abstract Staphylococcus aureus biofilms are a major problem in modern healthcare due to their resistance to immune system defenses and antibiotic treatments. Certain analgesic agents are able to modulate S. aureus biofilm formation, but currently no evidence exists if paracetamol, often combined wit...
