Bacterial community profiles determined by shotgun and 16S rRNA gene sequencing data. Comparison of bacterial profiles analysed by shotgun and 16S rRNA gene sequencing data. Normalised data and relative abundance of the bacterial taxa was represented in percentages of number of reads. Bar colours represent different genus taxa, and bar lengths signify the relative abundance of each taxon. 16S rRNA bacterial profiles are named according to the different 16S rRNA hypervariable region amplified: (V1 + V2 + V3, primers 27F-519R), (V4 + V5, primers 530F-926R), and (V6 + V7 + V8, primers 926F-1394R). a Bacterial community profiles determined by shotgun and 16S rRNA gene sequencing from an ELBW infant (sample AP8C) with no supplementation. b Bacterial community profiles determined by shotgun and 16S rRNA gene sequencing from an ELBW infant (sample P29F) with supplementation. c Bacterial community profiles determined by shotgun and 16S rRNA gene sequencing from a term baby (sample V3 J).
