Fig. 3From: Cilantro microbiome before and after nonselective pre-enrichment for Salmonella using 16S rRNA and metagenomic sequencing a Alpha diversity measured using Shannon entropy and Faith’s whole-tree phylogenetic diversity. Both metrics indicate a significant increase in the diversity of T0 sample communities relative to the T24 group (P < 0.002; Mann–Whitney test). b Principal coordinates analysis reveals a distinct clustering of samples by T0/T24 status.
