The secondary objectives are:~A. Should a first regimen of antibiotics fail, to describe the bacterial community present in the wound, and its potential to create biofilms.~B. To investigate the role of antibiogramme-antibiofilmogramme concordance (in terms of S. aureus strains and prescribed antibiotics) in wound healing.~C. To study the potential role of additional antibiofilmogramme data, as well as that of other pre-defined co-factors, in predicting wound changes.~D. Create an S. aureus strain collection for future ancillary studies.
This is an observational study that does not change routine care.~The primary objective of this study is to investigate the role of antibiogramme-antibiofilmogramme concordance (in terms of S. aureus strains and prescribed antibiotics) in the presence/absence of S. aureus strains at the end of a first regimen of antibiotics.
