Intestinal bacterial cooccurrence microbiome networks between different processing groups. A Network analysis of different groups. Each point in the figure represents a species, and species with correlations are connected by a line. Red lines represent positive correlations, green lines represent negative correlations, and the intensity of the line represents the level of correlation. B NetShift analysis of different groups. Potential “driver taxa” of infection based on bacterial network analysis of the experimental group (P, K, CuP, CuK, and Cu) and the control groups (Lb), marked as P vs. Lb, K vs. Lb, CuP vs. Lb, CuK vs. Lb, respectively. Node sizes are proportional to their scaled NESH (neighbor 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 different conditions. 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.
