The issue and study of the human microbiome in the recent years have significantly changed the view on the aetiology
and treatment of many diseases. In the obstetrics, the relation between mother’s settlement and another development
of the foetus appears as crucial. The relation to some pathologies in pregnancy is a subject to intensive investigation.
The composition and the quality of microbiome surely will not be a main aetiological mechanism of preeclampsia
origination. However, it seems that in case of preeclampsia the quality or possibly modulation of microbiome may
have an impact on the origination and course of this severe pathology in pregnancy.
