Taxonomic distribution of the phylotypes.

<p>*The percent in diseased sites is only shown for families present at more than 1% of the total number of sequences * The percent in diseased sites is only shown for families present at more than 1% of the total number of sequences (1237).</p

Statistics for major bacteria in principal component analysis.

<p>Species labelled * are significant in k-means clustering.</p

MrBAYES tree of the <i>Fusobacterium</i> genus.

<p>Phylotypes found in our study are colored red. The <i>F. necrophorum</i> complex is shown as a grey box.</p

MrBAYES tree of the Prevotellaceae family.

<p>Nodes with a statistical support (posterior probability) > = 95% are circled. Phylotypes and highly supported nodes are colored green or red according to their prevalence in healthy or diseased sites, respectively (see text for details).</p

Radial plot of means for significant bacterial species or phylotypes in K-means clustering.

<p>Polygons of means for healthy and diseased sites are colored in green and red, respectively.</p

Plot of the libraries and the most discriminant bacterial species by principal component analysis.

<p>A: Libraries from healthy and diseased sites are colored green and red, respectively. B: Bacterial species or phylotypes are color-coded according to their weight in healthy (green) and diseased (red) libraries.</p
