FIG 2.

Prevalences of the oral treponeme pyrH genotypes detected in the periodontitis (P) and gingivitis (G) subject groups. The heights of the bars indicate the detection frequencies of the pyrH genotypes (pyrH001 to pyrH034) in the P and G subject groups (i.e., indicate the total number of subjects that tested positive for each pyrH genotype). The colors represent the prevalences within the subject groups as shown below the graph. The numbers in the bars indicate the clonal abundances of the 34 pyrH genotypes (i.e., the corresponding number of cloned pyrH gene sequences) in the P and G subject groups (out of a total of 1,224 cloned pyrH gene sequences). Thirteen pyrH genotypes (pyrH022 to pyrH034) were identified by a single cloned pyrH gene sequence.
