  1. NOTE. Blood and/or bone cultures were performed in all 70 patients. MSSA = methicillin-susceptible Staphylococcus aureus. MRSA = methicillin-resistant S. aureus. There were five cases of coagulase-negative staphylococci diagnosed with blood cultures, and two diagnosed by bone biopsies and blood cultures. The single Propionibacterium sp. infection was diagnosed by bone biopsy. There were two polymicrobial infections: one Staphylococcus aureus infection together with unidentifiable Gram-negative bacilli, and one coagulase-negative staphylococcal and Corynebacterium sp. infection.
