Microbial functions computationally predicted present in neonatal microbiota along the first month of life. a, b Discriminant analysis of principal components (DAPC) of the neonatal (a) and infant fecal microbiota at 7 days and 31 days (b). Adonis analysis was used to stablish the significance of studied variables. c, d Computational analysis of lipopolysaccharide (LPS) biosynthesis (c) bacterial toxins (d) routs presents in the fecal microbiota of newborns along the first month of life. Results were expressed as percentage of total functional routs for each sample. *p < 0.05, **p < 0.01, ***p < 0.001. C-section (CS, n = 65), hospitalized vaginal delivery (VAG, n = 92), and homebirth (HB, n = 23)
