Haemophiltus parainfluenzae seldom causes human infections. It has been isolated in clinical specimens of patients with pneumonia, meningitis and endocarditis but rarely in bone or joint infections. We present a 62 years old man with an intense pain in his neck and left shoulder. Two sets of blood cultures were positive for Haemophilus parainfluenzae. Bone scan and CT suggested a septic process in the clinically affected areas. Posterior evolution confirmed the presence of an underlying infectious endocarditis. Ampicillin first and ciprofloxacin afterwards were the antibiotic, treatments. This quinolone has a good penetration into the bone and, as an oral treatment, it can be a good alternative for osteoarticular infections in outpatients, However, controversy exists about its efficacy when infectious endocarditis is suspected.
