Similar to our findings, a comparative study concerning hematogenous vertebral osteomyelitis by GNB vs. methicillin-sensitive Staphylococcus aureus (MSSA) showed that patients with MSSA hematogenous vertebral osteomyelitis were more likely to have epidural abscess, and CRP values were higher in MSSA infection [6]. Here, CRP is linked to epidural abscess.
