Prevalance of preterm birth-associated species in samples from pregnant subjects. Stacked barplot of the percentage of reads from preterm birth-associated bacterial taxa in African Americans versus women of European ancestry.

The plot is based on americans black females pussy African Americans and 76 pregnant women of European ancestry. Of these subjects, 33 African Americans and five European ancestry women were diagnosed with BV and African Americans and 45 women of European ancestry were healthy.
