Comparison between C-reactive protein (CRP) levels and treatments given over time. The first antibiotic regime was cefotaxime and gentamicin administered for three days. After the prosthetic valve surgery, the patient received antibiotics for four months. Twelve weeks after surgery, CRP was found to be repeatedly at a normal level. Only the initially drawn blood cultures showed growth of Mycobacterium goodii. The broken line indicates CRP ≤ 3.0 g/L.
