Background

Staphylococcus epidermidis is one of the main organisms associated with prosthetic joint infections. One of the major pathogenic attributes of this organism is the ability to form biofilms, making it extremely resistant to currently available antimicrobial therapies. There is, therefore, an urgent requirement for novel agents that are effective against this organism. Antimicrobial peptides represent a novel group of agents that show good activity towards biofilm-forming S. epidermidis. Antimicrobial peptides are particularly interesting due to their multiple modes of action which are thought to reduce the rate of resistance development to the agents.
