Maternal parity predicts variation in alpha diversity of the infant gut and maternal milk microbiota

(A) The infant gut microbiome exhibits significantly lower Shannon Indices than maternal reservoirs at T1 (2–5 days old), but converges toward maternal levels by T2 (4 months old) and remain similarly high at T3 (6 months old).

(B) Shannon Indices (partial residuals) at T1 (2–5 days old) are lowest in low parity infants.

(C) The maternal milk microbiome of low parity females is more diverse (partial residuals of Shannon Indices) than high parity females.
