Short summary
We define an algorithm to optimize bone and joint infection diagnosis in adults on synovial fluid samples. This prospective multi-center study included a large number of synovial fluids and compared the performance of classical culture on different media, inoculation of synovial fluid in blood culture bottles, and broad-range and specific PCR. We proposed an algorithm associating culture onto three solid media and into blood culture bottles and 16S, Staphylococcus, and Streptococcus PCR.
