Scatter plot of Pearson’s correlation coefficienct (r) between Lactobacillus murinus (A), Lactobacillus johnsonii (B), and Lactobacillus rueteri (C) abundance and neurological score or histological score.

(D) Pearson’s correlation matrix between different variables. Pearson correlation coefficient values (r) are shaded with different color codes: positive correlations are from white to blue on the color scale, and negative correlations are from white to red. No negative correlation was seen between these variables. Bacterial abundance was qPCR data. A.U., arbitrary unit. n = 6 mice in the uninfected and infected group.
