Endovascular Infection with Kingella kingae Complicated by Septic Arthritis in Immunocompromised Adult Patient.

We report a case of Kingella kingae endovascular infection in an immunocompromised elderly patient in Israel who had culture-negative septic arthritis. This case highlights potential sources of metastatic infection other than infective endocarditis, and emphasizes the need for molecular diagnostic methods in detection of pathogens in culture-negative septic arthritis in immunocompromised patients.
