Prosthetic joint infection due to Haemophilus aphrophilus

A case of prosthetic joint infection due to Haemophilus aphrophilus is presented. A 76-year-old woman, with a long history of pain in her left hip and raised inflammatory markers, underwent prosthetic joint excision. Six samples of pus and tissue were taken from the joint and Haemophilus aphrophilus was cultured from 3 of these specimens. We review the clinical and microbiological findings. Treatment with ciprofloxacin after removal of the prosthesis resulted in clinical improvement
