MUC5AC and prediabetes syndrome: Interestingly, after a 12-month follow-up, we identified eight abundant SCFA-producing genera: Fusicatenibacter, Atopobiaceae, Coprococcus 1, Lachnospiraceae ND 3007 group, Anaerostipes, Dorea, Lachnospiraceae FCS020 group, and Blautia. Surprisingly, Akkermansia and other mucin-degrading bacteria were not significant in subjects with prediabetes, contrary to T2D reports37–39.
