Case Reports

Case: An 65-year-old immunocompetent female developed a Leclercia adecarboxylata infection following the repair of closed olecranon fracture. L. adecarboxylata is associated with polymicrobial infections, infections in immunocompromised patients and penetrating or open wounds. Following speciation, intravenous ceftriaxone was started. Two weeks later, the patient presented with leukopenia and neutropenia. Per infectious disease recommendations, the patient was switched to intravenous ertapenem with resolution of both infection and neutropenia. The olecranon fracture went on to heal fully.

Conclusions: This case describes a rare postoperative monomicrobial infection with L. adecarboxylata in an immunocompetent host following musculoskeletal trauma and identifies L. adecarboxylata as a potential emerging hospital-acquired pathogen following orthopedic surgery.
