Figure 2. The presence of bacterial DNA within the culture media and PCR amplification from the automated blood culture system. A: Automated blood culture media (20 ul) directly loaded on 0.7% agarose gel electrophoresis after centrifugation. MW is the 1kb molecular weight marker. B: 6% non-denaturing acrylamide gel electrophoresis of PCR amplification using the DNA from the automated blood culture bottles. MW is the 100 bps molecular weight ladder
