Gram-positive cocci, including Staphylococcus aureus, Staphylococcus epidermidis, and other coagulase-negative staphylococci, are common causes of periprosthetic joint infections (PJI). This is the first reported case of PJI caused by Kytococcus schroeteri, a rarely encountered Gram-positive coccus. K. schroeteri, which belongs to the micrococcus branch, is typically found as a symbiotic bacterium on the skin.
Oftentimes, Gram-positive cocci are the cause for periprosthetic joint infections (PJI). Most of these infections include bacteria such as Staphylococcus aureus, Staphylococcus epidermidis or other coagulase-negative staph-ylococci. We here present the first case of a PJI caused by Kytococcus schroeteri. While being a Gram-positive coccus, it is very rarely the cause for infections in the human body. K. schroeteri is part of the micrococcus branch and often encountered as a symbiotic bacterium living on the skin. Regarding its pathogenic poten-tial, not a lot is known since less than a few dozen human infections have been reported worldwide. Further-more, many of the cases reported are either associated with implanted material, especially heart valves, or associated with patients whose immune response is deficient. Only 3 reports of osteoarticular infections are described so far. (c) 2023 Elsevier Inc. All rights reserved.
