FIG. 1.

Clustering of vaginal microbial communities in women with and without frequent VVC based on the data from T-RFLP analysis of 16S rRNA genes. The red line indicates the clustering threshold determined by using three statistical cluster criteria (1). Samples from patients with frequent VVC are indicated by a shaded background. Clusters for more than three women are indicated by different colors of shading and roman numerals. Cluster V is not indicated because it was a “singleton” and was obtained for only one subject (branch on the right). Asterisks indicate the samples used to construct libraries of cloned 16S rRNA genes.
