The role of biofilm formation in the pathogenesis and antimicrobial susceptibility of .

(previously known as ) is frequently found on lipid-rich parts of the human skin. While is most known for its role in the development and progression of the skin disease acne, it is also involved in many other types of infections, often involving implanted medical devices. readily forms biofilms and there is growing evidence that biofilm formation by this Gram-positive, facultative anaerobic micro-organism plays an important role and is also involved in treatment failure. In this brief review we present an overview on what is known about biofilms (including their role in pathogenesis and reduced susceptibility to antibiotics), discuss model systems that can be used to study these biofilms and and give an overview of interspecies interactions occurring in polymicrobial communities containing .
