Networks (a) and co-occurrence networks (b) based on intra- and intergroup intestinal microbiomes. a Network analysis between the control groups (Lb, Wa) and the experimental group (Eh). Each point in the figure represents a species, and those species with correlations are connected by a line. The red line represents a positive correlation, the green line represents a negative correlation and the depth of the line represents the level of correlation. b Potential “driver taxa” of infection based on bacterial network analysis of the experimental group (Eh) and the control groups (Lb, Wa), marked as Eh–Lb and Eh–Wa, respectively. Node sizes are proportional to their scaled NESH (neighbour shift) score (a score identifying important microbial taxa of microbial association networks), and those nodes colored red were important driver taxa. As a result, large red nodes denote particularly important driver taxa under conditions of E. hormaechei feeding. Line colors indicate node (taxa) connections as follows: red edges, association present only in experimental groups; green edges, association present only in control groups; blue edges, association present in both the experimental and control groups
