Viable colony counts and fraction of aerobic colonies. a Viability. Bacterial density (BGE/ml: bacterial genome equivalents per ml) derived from pan-bacterial PCR of DNA (x-axis) are compared with viable colony counts (CFU/ml). Results are plotted on log-log scales, with each point representing a single research subject. The dotted line represents theoretical 100% colony-forming viability of bacteria detected by DNA. b Aerobic Fraction. Bacterial density in BGE units/ml (x-axis) is plotted on a log scale against the fraction of aerobic colonies, as derived from Table 1. In each case the Pearson correlation coefficient r and p-value for the null hypothesis of r = 0 were calculated
