Fig. 2. Reading graphs of blood culture bottle of the first patient (A) showed positive flag within less than a day after starting to incubate in the automated blood culture system. Additional incubation of blood cultures revealed no change of peaks in reading graphs until 5 days. (B) Normal positive flag within a day showed abrupt peak at 13 hours after incubation.
