Highlights
- •
Stool samples from 122 children diagnosed with acute diarrhea were recollected for detection of STEC and EPEC pathotypes.
- •
E. coli were detected in 68% of the stool samples, of which 18.8% were STEC or EPEC.
- •
STEC O145 and EPEC O130, O113 and O157 were the serotypes detected.

Highlights
- •
Our study revealed noticeable differences in the gut microbiome of women with GDM.
- •
In GDM women's gut, Bifidobacterium, Serratia, and Sutterella were in low abundance.
- •
The diversity and abundance of gut bacteria in GDM infants are similar to that of their mothers.
- •
The analysis of GDM HBM showed Sutterella, Serratia, and Lactococcus in low abundance.
- •
Our results suggest that GDM women could lead to dysbiosis in breast-fed infants.
