Serratia marcescens pyarthrosis and osteomyelitis.

We have reported a case of Serratia marcescens arthritis and osteomyelitis in a young man whose source of infection appeared to be a single episode of intravenous amphetamine use. Multiple antibiotics and aggressive surgical management were necessary to effect a cure. He eventually responded to a three-week course of amikacin and moxalactam given in conjunction with surgical debridement of all involved areas.
