The Impact of Age and Pathogens Type on the Gut Microbiota in Infants with Diarrhea in Dalian, China

Figure 3

The beta diversity and predominant microbiota of healthy and diarrheic infants. (a) The nonmetric multidimensional scaling (NMDS) of beta diversity is calculated on ranking order. (b) The ANOSIM Similarity Analysis is based on a nonparametric test to compare intragroup and intergroup differences. (c) Cladogram indicating the phylogenetic distribution of microorganisms as related to group characteristics; the difference was shown in red for the healthy group and green for the diarrhea group. The diameter of each circle was proportional to the taxa’s abundance. The strategy of multiclass analysis was not strict (at least one somewhat differential). The circle from inside to outside represented the phylogenetic level from domain to genus. (d) Indicator microbial groups within the two types of sediments with a linear discriminate analysis (LDA) value greater than 4.0. The color lump represented the microbes with a significant difference at different taxonomic levels. Red and green represented the healthy group and the diarrhea group, respectively. The x-axis represented the LDA score of the microbes. The y-axis represented the microbes, which were detected to be significantly different in the groups.
