Figure 3 : Shared microbial features between maternal faeces (M), placenta (PL), amniotic fluid (AF), colostrum (C), meconium (Me) and infant faeces (INF) samples.

From: Human gut colonisation may be initiated in utero by distinct microbial communities in the placenta and amniotic fluid

Figure 3

(A) Venn diagram of exclusive and shared family-level phylotypes (non-singleton OTUs, sequences at greater than or equal to 97% sequence identity and present >1%). (B) A neighbour joining phylogenetic tree representing the sequences obtained from maternal faeces samples, placenta, amniotic fluid, colostrum, meconium and infant faeces samples. Maternal faeces (pink), placenta (yellow), amniotic fluid (red), colostrum (light blue), meconium (dark blue) and infant faeces (green) samples are shown as single points. (C) Representative fingerprints of different samples types from four mother-infant pairs obtained by DGGE-PCR targeting the 16S rRNA gene. (D) Heatmap plot of Hierarchical Ward-linkage clustering based on the similarity measure (Euclidean distance) of phylum proportion. Unassigned & unmapped reads were excluded and also, variables with over percent zeroes were removed. Sequences were normalized by log transformation. Individual maternal faeces (pink), placenta (yellow), amniotic fluid (red), colostrum (light blue), meconium (dark blue) and infant faeces (green) samples are shown as single points.
