Hyperglycemia is one of the metabolic characteristics of gestational diabetes mellitus (GDM). Considering that GDM is able to cause changes in the gut bacterial community and function in the mother's intestine compared with healthy pregnant women, we aimed to clarify the correlation between hyperglycemia and gut microbiota in a GDM mouse model. Mice were divided into four groups: CE0, GDME0, CE18, and GDME18. C and GDM represent the control (C) and GDM groups, while E0 and E18 represent early or late trimesters of embryo day 0 or 18, respectively. GDM mouse models were created by injecting streptozocin on embryo day 0. The gut microbiota was characterized using the Illumina MiSeq platform targeting the V3-4 region of the 16S rRNA. Operational taxonomic unit analysis revealed a significant difference between CE18 and CE0, in which Akkermansia and Prevotellaceae were more abundant in the early trimester group, CE0. Moreover, the Clostridiales_vadinBB60 group was more abundant, while Parasutterella was much lower in GDME18 than in CE18. The gut microbiota community structure correlated with the GDM state, and LEfSe and molecular ecological network analysis further confirmed these diversities. Our research shows that changes in the community structure of the gut microbiota from the early to late trimester correlate with the GDM state. Changes in the abundance of the probiotic bacteria Akkermansia, Prevotellaceae , and Parasutterella may be involved in the GDM state.
