- Abstract
- While the importance of breastfeeding on the developing infant gut
microbiota has been established, few studies have compared the effect of
breastfeeding duration on infant gut microbiota development. In this
pilot study, we included 23 infants, divided into 4 groups to compare
the effect of breastfeeding duration for first 4 (BreastFed_4) or 8
weeks (BreastFed_8) compared to exclusive breast (Exc Breast Fed) or
formula feeding (Formula Fed) for 6 months. We used metagenomics shotgun
sequencing of 88 infant stool samples and 64 corresponding maternal
milk samples to examine the microbial composition. Breast milk samples
showed the presence of previously defined core bacteria including spp.

microbiota has been established, few studies have compared the effect of
breastfeeding duration on infant gut microbiota development. In this
pilot study, we included 23 infants, divided into 4 groups to compare
the effect of breastfeeding duration for first 4 (BreastFed_4) or 8
weeks (BreastFed_8) compared to exclusive breast (Exc Breast Fed) or
formula feeding (Formula Fed) for 6 months. We used metagenomics shotgun
sequencing of 88 infant stool samples and 64 corresponding maternal
milk samples to examine the microbial composition. Breast milk samples
showed the presence of previously defined core bacteria including spp.
belonging to Staphylococcus, Streptococcus, Corynebacterium, Cutibacterium, Rothia and Pseudomonas.
We report that the Exc Breast Fed infant group had the lowest alpha
diversity and a distinct microbial composition compared to the Formula
Fed group. BreastFed_4 clustered distinctly from all other groups,
indicating the impact of duration and time of feeding on infant
microbiota. Certain Bifidobacterium spp. were more associated to certain groups, in particular, B. infantis was more associated to Exc Breast Fed while Bacteroides/Phocaeicola with BreastFed_8. Exc Breast Fed showed the highest frequency of persisters with B. infantis being the dominant persister, while B. bifidum
was the dominant persister in Formula Fed group. Persisters showed
significantly higher abundance of several glycoside hydrolases (GH)
important in early life across all groups compared to non-persisters.
This study highlights infant gut microbiota changes associated with
breastfeeding duration, warranting more detailed studies on the impact
of breastfeeding duration on long-term health outcomes. (Less)
