  1. Non-parametric statistics were used to identify metadata variables significantly correlated with clustered OTUs lagged forward or backwards in time (q <0.05, Spearman correlation). Representative taxonomic names from each cluster are shown along with the percentage of overall reads accounted for by each OTU cluster (‘Abundance’). Redundant correlations (for example, yogurt subtypes associated with the same OTU cluster) are shown in Additional file 9, and a full list of taxa associated with each cluster can be found in Additional files 10 and 11. We excluded Subject A’s travel period and Subject B’s post-infection period from metadata correlation analysis. No significant correlations were found among Subject B’s microbiota and metadata.
