Microencapsulated Bifidobacterium longum subsp. infantis ATCC 15697 Favorably Modulates Gut Microbiota and Reduces Circulating Endotoxins in F344 Rats

Figure 5

Correlations between the concentrations of fecal endotoxins and potential endotoxins-producing bacteria in F344 rats: (a) total Gram-negative bacteria, (b) family Enterobacteriaceae, (c) species Escherichia coli, (d) phylum Bacteroidetes, and (e) genus Bacteroides-Prevotella. F344 rats were gavaged daily with APA microencapsulated B. infantis ATCC 15697 or saline during 38 days ( ). Correlations were performed at endpoint (day 38) using Pearson’s correlation in the saline and APA microencapsulated B. infantis ATCC 15697 treatment groups. Indicates statistical significance of the correlation ( ).
