Summary

Bone and joint infections (BJI) is a public health issue in industrialized countries. Implant-associated BJI, are complex hospital-acquired infections and eradication of the pathogen is challenging in such patients. A prolonged antimicrobial therapy is usually required from 6 weeks to 3 months, but some patients are eligible to several years of treatment and most of patients report gastrointestinal troubles, such as nausea and mild to severe diarrhea (but very few developed C. difficile diarrhea). Moreover, the host gut microbiota is probably largely affected in abundance, richness and diversity. Indeed, it is known, that few days of antibiotics are sufficient to induce significant alterations of the gut microbiota, also called dysbiosis. Severe dysbiosis, which is potentially irreversible and associated with a definitive shift in the gut microbiota metabolism and host homeostasis, may lead to and/or promote a large panel of severe diseases such as Clostridium difficile infection, diabetes mellitus, obesity, inflammatory bowel disease (IBD), cirrhosis, neurological disorders and cancer. It may also be associated with BJI recurrence and then impact global health costs. The main objective of this study is to constitute biobanking of stools and perform DNA sequencing of the gut microbiota in patients with acute or sub-acute implant-related Bone and Joint Infection (BJI), caused by Staphylococcus aureus.
