In this study, we report the first case of recurrent PJL caused by the same L. monocytogenes strain three years and three months after the first infection. L. monocytogenes.

In this study, we report the first case of recurrent PJL caused by the same L. monocytogenes strain three years and three months after the first infection. L. monocytogenes. We confirmed the strain's ability to form biofilm on prosthetic material surfaces and assess the genomic changes over the three years and three months period. We propose that PJL can lead to biofilm contamination of the joint, offering L. monocytogenes protection against antibiotic treatment and shear stress (e.g. debridement), resulting in asymptomatic persistence of the same strain beyond the time scales previously described
