| Outline of Final Research Achievements |
We investigated microbial colonization in intrauterine environment and cystic fluid of women with and without endometriosis. 16S rDNA metagenome sequence analysis was done by Illumina Miseq system. 16S metagenome assay in endometrial swabs indicated that proportion of Lactobacillacae was significantly decreased (P<0.01) and of Streptococcaceae, Staphylococaceae, Enterobacteriaceae was significantly increased (P<0.05 for each) in GnRHa-treated women with endometriosis than in GnRHa-untreated women. A significantly higher percentage of Streptococcaceae (P<0.01) and Staphylococaceae (P<0.05) were found in the cystic fluid derived from women with ovarian endometrioma comparing to that in cystic fluid collected from non-endometrioma cysts. These findings indicate the occurrence of sub-clinical infection in intrauterine environment and in the cystic fluid of ovarian endometrioma.
