Bacterial communities associated with open fractures at emergency room presentation. The bacterial communities of open fracture wounds (left) and their corresponding adjacent, unaffected skin (right), as reported by Hannigan et al.²³ The communities were grouped into four anatomical categories. The top 10 bacterial families, calculated as median relative abundance across all samples, were calculated for the wound and skin groups. The bacterial communities upon patient presentation to the emergency room are shown. The skin communities are primarily dominated by Corynebacteriaceae and Staphylococcaceae, while the wound communities are less dominated by these or other bacteria. The wound and skin communities differ from each other at the same anatomical locations, and the different anatomically located communities also differ within the wound and skin categories. The bacteria labels are listed in the legend near the figure bottom. To see this illustration in color, the reader is referred to the web version of this article at www.liebertpub.com/wound
