Fig. 1.

Heatmap shows proportions of microbial species found in the vaginal bacterial communities of 67 pregnant women. As the colour key indicates, light green colour represents the absence of the organisms, and the darker coloured tiles indicate the presence of percentage of that particular organism. Lactobacillus crispatus was the dominant flora in the normal and intermediate group and L. iners was the more frequent organism in the positive group. Nugent's score and pH bars are shown on the right side of the Figure. The Nugent's score increased with increasing pH.
