Fig. 4.
Counts of CD4 + CD25- immune cells at the age of < 90 days correlate with relative abundance of Bifidobacterium genus and specifically B. longum in multiple linear regression analysis. Genus Bifidobacterium is significantly negatively correlated with the abundance of CD4 + CD25- cells (A). However, when stratifying the analysis by LOS status the negative correlation remains significant only for the control group (B). This deviation between the groups is even more pronounced for the species level assignment of B. longum, where the negative correlation is present for the control group but completely missing for the sepsis group
