title: Bacillus cereus: a significant pathogen in postoperative and post-traumatic wounds on orthopaedic wards.
abstract: Over a period of 19 months, Bacillus species, most frequently B. cereus, were isolated from postoperative and post-traumatic wounds in 24 patients on orthopaedic wards in a Swedish hospital. Clinical signs of infection were found in all but 3 patients: in 9 patients, mild signs with increased secretion from the wounds; in 10 patients, moderate signs with fever and/or significant local reaction around the wounds; and in 2 patients, severe signs with necrotic infections. Bacillus spp. were isolated from one-fourth of all patients with wound complications following total hip arthroplasty. Their hospitalization was significantly prolonged, compared with a control group (p = 0.0042). Isolates of B. cereus from wounds should not be dismissed as contaminants or as non-pathogenic, but must be assessed in the light of the clinical situation.
