SERT−/− mice have altered bacterial community structure. Bacterial-bacterial co-occurrence networks were generated for significant co-occurrences in (A) SERT+/+ and (B) SERT−/− mice. Bacteria are colored by class and sized is by betweeness centrality. Significant edge testing was determined using SPARCC with 500 bootstraps, p < 0.001 was considered significant. Differences in (C) network diameter, (D) clustering coefficient, (E) scale-free fit, and (F) overlap in edges display differential network structure.
