muciniphila and Lachnospiraceae bacterium A2 were significantly higher in the control group than in the AAA group, while six species were increased in AAA mice: Lachnospiraceae bacterium, COE1, Corynebacterium stationis, Firmicutes Bacterium ASF500, Helicobacter bilis and Clostridium leptum (Fig. 4a-b). This evidence concerns the gene EBF1 and triple-A syndrome.
