T-SNE plots summarizing the overall growth effects of bacterial cells (a) and secretomes (b) on six human cell lines. Colored circles correspond to strains belonging to particular bacterial families. Magenta and light blue shading around the circles indicate enhancing and inhibiting effects of strains, respectively. Families labeled as “Others” contains the following strains for bacterial cells (A): Lactobacillaceae (1), Peptostreptococcaceae (2), Desulfovibrionaceae (3), Eubacteriaceae (4), Bifidobacteriaceae (5), Enterococcaceae (6), Veillonellaceae (7), Synergistaceae (8), Burkholderiaceae (9), Pseudomonadaceae (10), Propionibacteriaceae (11), Ruminococcaceae (12), Akkermansiaceae (13), Acidaminococcaceae (14). And the following strains for secretomes (B): Lactobacillaceae (1), Eubacteriaceae (2), Clostridiaceae (3), Peptostreptococcaceae (4), Bifidobacteriaceae (5), Enterococcaceae (6), Veillonellaceae (7), Synergistaceae (8), Burkholderiaceae (9), Desulfovibrionaceae (10), Propionibacteriaceae (11), Ruminococcaceae (12), Pseudomonadaceae (13), Akkermansiaceae (14), Acidaminococcaceae (15), Bacillaceae (16).
