Pearson r correlation of identified genus with splenic lymphocyte population. Correlation graphs representing significant (p < 0.05) linear correlation between (A) CD45+ immune cells, (B) CD8+ T cells (Gated at CD45+ CD3+ CD4−), (C) CD4+ T cells (Gated at CD45+ CD3+ CD8−), and (D) FOXP3+ CD4 T cell populations in the spleen with the gut abundance of different genera irrespective of treatment groups. Sample identification in the correlation graphs: Control (O)- Black, CFUS (O)- Red, Control (Y)- Blue, and CFUS (Y)- Green.
