Polymicrobial interactions influence the agr copy number in Staphylococcus aureus isolates from diabetic foot ulcers

Diabetic foot ulcers are a major complication of diabetes and are often colonised by complex bacterial communities, where Staphylococcus aureus is frequently co-present with Pseudomonas aeruginosa. These bacteria interact through quorum sensing, encoded in S. aureus by the accessory gene regulator (...
