Venn diagram showing concordance of bacterial taxa inferred by different 16S rRNA sequencing platforms. (a) Concordance of the top classified species between Illumina sequencing, coupled with MSR and Illumina_BLAST+ analysis, and Sanger sequencing. (b) Concordance of the top classified species between Nanopore sequencing, coupled with Epi2ME and nanoBLAST+, and Sanger sequencing. (c) Concordance of the top classified species among Sanger 16S, resolved Illumina 16S, resolved Nanopore 16S, and reference standard.
