Correlation analysis of ARGs and bacterial community based on network and Procrustes analysis. a. Correlation-based network statistical analysis reveals the co-occurrence patterns among ARG subtypes and bacterial OTUs. The nodes were colored according to modularity class. The size of each node is proportional to its number of connections. The edges present the correlation between two nodes. A connection represents a strong (Spearman’s rank correlation coefficient ρ > 0.6) and significant (P value < 0.01) correlation. Modularity index 0.786. b. Procrustes analysis depicts correlation between ARG content (Bray-Curtis) and bacterial community (Bray-Curtis), M 2 = 0.606, P < 0.01
