Fig. 2From: Amniotic fluid from healthy term pregnancies does not harbor a detectable microbial communityThe bacterial microbiota of amniotic fluid is indistinguishable from controls. a Richness (number of bacterial OTUs) of each sample type by sequencing depth. b PCoA of unweighted UniFrac distances. c Bray-Curtis dissimilarity analysis compared within sample type and between sample type and buffer control. Statistical significance was assessed by Mann-Whitney test. d Relative abundance of bacterial OTUs unique to amniotic fluid and not present in negative controlsBack to article page
