FIG 3.
Evaluation of gut microbiota persistence in SS2 and SS4. (a) Bar plot representing results from 16S rRNA gene profiling of SS2, SS2_T6m, SS4, and SS4_T6m at the genus level. Only taxa with relative abundances of >5% in at least one sample are shown. u.m., unclassified members. (b) The bifidobacterial taxonomic profiles in SS2, SS2_T6m, SS4, and SS4_T6m obtained through bifidobacterial ITS profiling. (c) Heat map showing persistence of bifidobacterial OTUs (putative bifidobacterial strains) in SS2 and SS4 after 6 months. The most represented OTUs in the infant samples of SS2 and SS4 are highlighted in blue and green, respectively.
