Table 3 Average composition of the jejunum by genus and its correlation with bacterial load

From: The human jejunum has an endogenous microbiota that differs from those in the oral cavity and colon

  1. Percentages represent average metagenomic abundance of the genus over all 20 subjects, as a percentage of all bacteria (col 2). Linear Pearson correlation of genus abundance with log of the DNA-Based total microbe count (col 3). The Pearson correlation coefficient was used to determine the P-value (column 4) for the null hypothesis that there is no correlation between genus abundance and bacterial load. Only Rothia, Lachnoclostridium, Campylobacter and Ralstonia differed significantly from the null hypothesis (shaded cells). Columns 5–8 display the genus and its taxonomy
