  1. n represents the number of samples in each group.
  2. (a) All-bacteria results obtained by qPCR were expressed as the mean of the log10 value ± SEM.
  3. (b) Results were expressed as the mean of the log10 value ± SEM of normalized data calculated as the log of targeted bacteria minus the log of All-bacteria number.
  4. The non parametric Wilcoxon test was performed.
  5. Data not sharing the same letter within a column are significantly diferrent at p < 0.05.
