Chronic Infections on Articular Prostheses With C. Acnes Diagnosed by Specific PCR

Chronic Infections on Articular Prostheses With C. Acnes Diagnosed by Specific PCR : Descriptive Study of 6 Patients

Osteaoarticular infection due to C. acnes are known to be of late onset, causing chronic infection possibly pauci-symptomatic. Osteaoarticular infection due to C. acnes represents a diagnostic challenge, since C. acnes is slow and difficult to grow, and can also be considered a contaminant.A 16S universal PCR bacteriological diagnosis has been proposed but is lacking of sensitivity. A specific C. acnes PCR was developed in 2010, but is not used routinely.

Inclusion Criteria:

• patients having had infection prothesis vith C. acnes identified by PCR

Exclusion Criteria:
