Quantification of Streptococcus salivarius using the digital polymerase chain reaction as a liver fibrosis marker

Figure 3 Comparison of bacterial load measured using digital PCR and quantitative PCR. A: Quantitative PCR (qPCR) can reliably detect bacterial concentrations down to 6.40 × 10² colony forming unit (CFU)/mL using a 1 μL sample volume; B: Digital PCR has a higher sensitivity than qPCR, as it can detect lower concentrations of bacteria (6.40 × 10² CFU/mL) with greater accuracy and precision. dPCR: Digital PCR; qPCR: Quantitative PCR; CFU: Colony forming unit.
