Bacterial phylotypes in the small intestine whose population level increased upon PG-administration.

<p>Percent increase was calculated by subtracting the percent population level of each specific phylotype found in the PG-administered mice with that found in the PBS control mice. Associations between bacterial phylotypes and PG administration were examined by Fisher exact test. The phylotypes having <i>P</i> values less than 0.05 at least in 2 groups (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0075008#pone.0075008.s007" target="_blank">Table S6</a>) are shown. Asterisks *, ** and *** indicate bacterial phylotypes having <i>P</i> values less than 0.05 in 3, 4 and 5 groups, respectively. §: Saccharolytic bacteria, †: short-chain fatty acids-producing bacteria, ‡: bacteria with immunomodulatory effect, ▲: disease-associated bacteria.
