ABSTRACT
[ ABSTRACT]

AIM:

To investigate the characteristics of the intestinal microbial flora in the pregnant women with congenital heart disease fetus ( PW group) and normal pregnant women ( NW group) .

METHODS:

Stool samples were collected from 15 NW and 17 PW cases.The bacterial genomic DNA was extracted.The 16S rDNA was amplified by PCR, and the second generation of Illumina sequencing was conducted.

RESULTS:

We obtained 2 696 276 ( NW group) and 2 445 530 ( PW group) optimized sequences.The coverage was greater than 97%.We obtained 77 243 operational taxono-mic units ( OTUs) in NW group and 75 600 OTUs in PW group after a 97%similarity merge.In NW group, the Chao 1 in-dex and the Shannon index were greater than those in PW group.The diversity analysis of microbial population indicated that they were mainly composed of Firmicutes, Proteobacteria and Actinobacteria.In family, the Bifidobacteriaceae and Cori-obacteriaceae were significantly different through analysis of variance.

CONCLUSION:

The Bifidobacteriaceae and Cori-obacteriaceae may play an important role in the occurrence of congenital heart disease.
