Abstract:
Recurrent pregnancy loss (RPL) is one of the most difficult problems in reproductive health since
Effective treatments are rarely accessible and its causes are frequently unclear.To identify the independent culture vaginal microbiota of recurrent aborted women by sequencing 16S ribosomal RNA .Vagina specimens were collected from recurrent abortion women . Multiplex PCR technique was performed based 16S RNA gene to identify the uncultured bacteria. The DNA sequencing method was performed using Sanger’s method and phylogeny for mutation analysis by using NCBI BLAST analysis. Megasphera, Atopobium, Mobiluncus, Erysipelothrix, Catibacterium, and Bifdobacterium were diagnosed . This alignment study revealed the 16S ribosomal RNA gene’s substitution mutations and nucleotide alignment similarities across isolates . Phylogenetic tree analysis of local isolates related to NCBI-BLAST showed genetic relationship with some variation or substitution of nitrogen bases of target nucleotides. The maternal vaginal microbiome has an important role in the recurrent pregnancy loss etiology.
