Endometriosis and Peritoneal Dysbiosis

Biological materials (stool, peritoneal/ovarian cyst fluid, endometrial aspirate) will be secured and then subjected to molecular analysis using the Next Generation Sequencing (NGS) method. The stages will include: i) isolation of bacterial DNA from biological materials, ii) preparation of libraries for sequencing, including the performance of the PCR and nested-PCR methods on bacterial DNA isolates from the tested samples of biological materials, iii) purification of amplification products, indexing, validation of the concentration of amplicons, pooling and denaturation of libraries, iv) standardization and optimization of the procedure for the isolation of bacterial metagenomic DNA from biological materials from intestines, peritoneal cavity, uterine cavity and endometrial tissues, v) standardization of the nested-PCR method on bacterial DNA isolates from the tested biological materials, vi) submission of samples for sequencing.
