From: Identification of the core bacteria in rectums of diarrheic and non-diarrheic piglets
Co-correlation network analysis of bacterial genera constructed in diarrheic and non-diarrheic piglets. Co-correlation networks were deduced from the top 20 genera identified upon16S rRNA sequencing. Each node represents a genus, the size of each node is proportional to the relative abundance and the color of the nodes indicates their taxonomic assignment. The width of the lines indicates the correlation magnitude, while red represents a positive correlation and green a negative correlation. Only lines corresponding to correlations with a magnitude greater than 0.5 are shown. Co-correlation network of (A) Escherichia-Shigella genus in the diarrheic group (clustering = 0.82, closeness centrality = 0.86) and (C) Prevotellaceae UCG-003 genus in the non-diarrheic group (clustering = 0.30, closeness centrality = 0.34). Comparison of the relative abundance of (B) the genus Escherichia-Shigella and (D) the genus Prevotellaceae UCG-003 between diarrheic and non-diarrheic samples, which were visualized based on the means ± SEM. An independent t test was used to identify differences between groups. *P < 0.05; **P < 0.01; ***P < 0.001.
