Fig. 4From: Rapid change of fecal microbiome and disappearance of Clostridium difficile in a colonized infant after transition from breast milk to cow milkThe structure of microbial communities is distinct before and after weaning. Principal coordinate analysis based on unweighted UniFrac metrics indicates that microbiota community structures are distinct between pre-weaning (blue dots) and post-weaning (red squares) fecal samples. Weaning happened between experiment days 224 and 230. On experiment day 292 when the infant produced two loose stools, significant alteration of the microbiota composition was observedBack to article page
