Variations of food-associated resistome profile and microbiota taxonomy. Principle coordinate analysis (PCoA) plots of calculated Bray–Curtis dissimilarities between food enrichment culture samples were constructed based on samples’ ARG profiles (A) and genus-level taxonomic composition (B). Procrustes analyses (C) were conducted to examine the degree to which bacterial and ARG profiles were correlated with each other. Arrows indicate changes in ordination position when resistome (square) were compared to the microbiome (circle) of individual samples
