Comparison of microbial community composition in infants, toddlers and mothers. (A) Overall composition differed among infants, toddlers and mothers, as shown in a Bray Curtis Multidimensional Scaling plot where centroids are shown as square points. Multiple samples from a single individual were combined within each age range. A PERMANOVA analysis showed overall differences between the groups while post hoc PERMANOVAs showed significant differences between mothers and either of the baby groups (mothers:0–2 month p = 0.0039; mothers:10–12 month p = 0.078). (B) Shannon diversity and (C) richness varied significantly among age groups (by Kruskal-Wallis), and increased with increasing age (by LME). Bars indicate significant post hoc comparisons (Mann Whitney test) with the two asterisks showing p values between 0.01 and 0.001. The mean number of species detected per infant from 0–2 mo of age was 30, from 10–12 months it was 33, and in mothers it was 83 (95% CI = 14–47, 15–50, 64–102, respectively).
