A rare case of ankle peri-implant infection by multi drug resistant Chryseobacterium indologenes.

Chryseobacterium indologenes is a rare human pathogen which is nowadays considered an emerging fearsome organism because of its upcoming antibiotic resistance. We present a quite unique case of a multi drug resistant C. indologenes surgical wound infection in a patient submitted to cannulated screw fixation of a displaced medial malleolus fracture. The microorganism was identified only after three months of attempts to treat pharmacologically the unhealed wound, by removing the ostheosynthesis device and sonicating it, and the surgical wound progressively restored by second intention.
