  1. Susceptibilities to the agents in Table 1 were evaluated by broth microdilution (MicroScan; Siemens, Tokyo, Japan).
  2. Isolate 1: blood culture on the first hospital day; Isolate1’: pus from the abscess on the first hospital day; Isolate 2: pus from the abscess on the sixth hospital day; Isolate 3: blood culture on the 40th hospital day; Isolate 4: pus from the abscess on the 55th hospital day. S: Susceptible; I: Intermediate; R: Resistant.
