FIG 2 .
Coronal sulcus bacterial densities and female partner bacterial vaginosis, stratified by coronal sulcus community state type. These box plots contrast the coronal sulcus bacterial densities in men with versus men without female partner BV, stratified by CST. There was an approximately 2-fold increase in bacterial density among men with a BV partner in the high-density group (CST4 to 7) (BV group mean of 4.5 × 108 versus normal group mean of 2.3 × 108 16S rRNA gene copies per swab; P = 0.06). In contrast, there was a 5-fold bacterial density decrease in the low-density CST group (CST1 to 3) (BV group mean of 8.2 × 106 versus normal group mean of 5.3 × 107 16S rRNA gene copies per swab; P = 0.04).
