Cardiac surgery induced intestinal flora dysbiosis. A. Phylogenetic distribution of fecal microbiota differences between the Con and Cardiac groups. Red colour is represented with significant differences of taxonomic representation in the Cardiac groups, while green color represents significant differences in taxonomic representation in the Con groups. The fecal microbiota shared between the Con and Cardiac groups is marked by yellow color. B. The taxonomy of the intestinal flora was analyzed by linear discriminant analysis (LDA) with effect size measurements (LEfSe). The length of bars in the chart represents the significance of differences in fecal microbiota between the two groups. For LDA scores >2, P<0.05 (n = 6). Compositions of different species of fecal microbiota associated with cardiac surgery and control rats assessed by LEfSe analysis. Con = control.
