Networks (A) and co-occurrence networks (B) based on intragroup and intergroup intestinal microbiomes. (A) Network analysis of the control group and P. aeruginosa Y12 group. Each point in the figure represents a species, and species with correlations are connected by a line. Red lines represent positive correlations, blue lines represent negative correlations, and the intensity of the line represents the level of correlation. (B) Potential “driver taxa” of infection based on bacterial network analysis of the Y12 experimental groups and the control group W, marked as Y12-W. Node sizes are proportional to their scaled NESH (neighbor shift) score (a score identifying important microbial taxa of microbial association networks), and the nodes colored red are important driver taxa. As a result, large red nodes denote particularly important taxa driving feeding on P. aeruginosa. Line colors indicate node (taxa) connections as follows: association present in only experimental groups (red edges), association present in only the control group (green edges), and association present in both experimental and control groups (blue edges).
