Mapping of quorum sensing interaction network of commensal and pathogenic staphylococci.

ABSTRACT: Staphylococci utilize secreted autoinducing peptides (AIPs) to regulate group behavior through a process called quorum sensing (QS). For pathogenic staphylococci, such as Staphylococcus aureus, QS regulates the expression of major virulence factors, and QS inhibition has been proposed as an alternative to antibiotics for the treatment of infections with methicillin-resistant S. aureus (MRSA). Here, we surveyed the interaction map between QS systems of the pathogens S. aureus, Staphylococcus epidermidis, and Staphylococcus lugdunensis and all the currently known staphylococcal AIPs, covering 21 different species. We identified six of these ribosomally synthesized and post-translationally modified peptides (RiPPs) in this study and compiled the full collection of
