Source: Text: Gut Microbiota Is Altered by Feeding Modality- (At 14 weeks, EBF infants had higher relative abundance of Streptococcus lactarius, as well as Actinomyces and Atopobium) and Supplementary Figure 2.

Description: Specific taxa differentially abundant in (exclusively breastfed) EBF versus (non-exclusively breastfed) NEBF infants at 14 Weeks. This study represents the gut microbial composition changes observed in non-exclusively breastfed (NEBF) infants compared to exclusively breastfed (EBF) infants.

Abundance in Group 1: increased abundance in Exclusively breastfed (EBF) infants at 14 weeks.

Description: Specific taxa differentially abundant in (exclusively breastfed) EBF versus (non-exclusively breastfed) NEBF infants at 14 Weeks. This study represents the gut microbial composition changes observed in non-exclusively breastfed (NEBF) infants compared to exclusively breastfed (EBF) infants.

Abundance in Group 1: decreased abundance in Exclusively breastfed (EBF) infants at 14 weeks.
