Cover Story: Chronic wounds, which respond poorly to treatment, are a major concern worldwide, affecting millions of patients every year. The microorganisms colonising the wound contribute to the establishment of chronicity through polymicrobial biofilm. Clinical management of chronic wounds relies on tissue debridement at regular intervals, which removes dead tissue, and the associated microbial communities, contributing to reorganize them. The complex network of species and interactions found in chronic wounds has the potential, through antagonist and/or synergistic crosstalk between different microorganisms, to accelerate or to impair wound healing. Understanding these interactions between microorganisms encountered in this clinical situation is essential to improve the management of chronic wounds. View this paper
