1. 1H NMR-based fecal metabolomics assessment of gut microbial functional activity in response to monkey milk, standard infant formula, or B. lactis-supplemented infant formula.
1H NMR-based fecal metabolomics assessment of gut microbial functional activity in response to monkey milk, standard infant formula, or B. lactis-supplemented infant formula. (A) Score plot from independent principal-component analysis (iPCA) of fecal metabolic profiles of infant rhesus macaques fed breast milk (BF, green), infant formula (FF, red), or infant formula supplemented with B. lactis (FF + B. lactis, blue). Ellipses were constructed based on multivariate normal distribution at 95% confidence interval. (B, C, and D) Multiple observations from the same rhesus monkey infant were age ascendingly linked by lines and presented as increasing thickness with age.
