Abstract

Haemophilus parainfluenzaeis a normal inhabitant of the human respiratory tract. However it is an increasingly recognized pathogen in invasive infections, particularly in the immunocompromised host and where there is disruption of the normal skin or mucosal barriers. We present a case of a 56-year-old female with a history of asplenia who developedH. parainfluenzaeseptic arthritis of the hip following an intra-articular steroid injection. We also summarize previously reported cases of bone and joint infections caused byH. parainfluenzae.
