| Outline of Final Research Achievements |
The gold standard for diagnosing periprosthetic joint infections (PJI) is bacterial culture. Unfortunately, it usually takes a few days for the results of these cultures to be obtained. In this study, the objective was to determine whether PCR-lateralflow (PCR-LF) tests could be used to effectively diagnose PJI. We used PCR-LF to diagnose common causes of PJI and compared the results to those from conventional bacterial cultures of the same samples. Two genetic markers specific to MRSA were being detected during this analysis. PCR results were interpreted as follows MRSA, MSSA, MR-CNS or negative. Our data indicate that PCR-LF was superior to bacterial culture tests in terms of sensitivity, particularly for PJI samples. In conclusion, our results showed that PCR-LF is a useful tool for identifying pathogenic bacteria in PJI.
