A,B, Comparison of gut bacterial diversity between AHDS and healthy dogs (HD) from the outbreak. A, Diversity as represented by the Shannon index was significantly reduced in dogs with acute hemorrhagic diarrhea syndrome (AHDS) (P < .001, Wilcoxon rank sum test; median, 2.7; range, 0.9–3.5) relative to healthy dogs (median, 3.2; range 2.6‐4.0). B, Dogs with AHDS had reduced observed species richness (P < .001; median, 67, median range 32‐91) relative to healthy dogs (median, 80; range, 69‐141)
