Group of flora markers for predicting stability of intracranial aneurysm and application thereof

The invention relates to the field of microorganisms, and particularly discloses a group of flora markers for predicting the stability of intracranial aneurysm and application of the flora markers. The bacterial flora marker is any one of a group consisting of a group consisting of ruminococcus, a group consisting of Fournierella, a group consisting of Ruthiobacillus, a group consisting of Ruthiobacillus, and a group consisting of anaerobic coccus, and the bacterial flora marker is any one of the group consisting of Ruminococcus, Fournierella, Ruthiobacillus, and anaerobic coccus. According to the invention, the intestinal flora is used as a detection marker, and the sample is noninvasive and easier to obtain, can be used for large-scale population screening, is beneficial to timely discovery of unstable intracranial aneurysm and dynamic monitoring of stable aneurysm, and reduces huge risks brought to patients by rupture of intracranial aneurysm. 本发明涉及微生物领域，具体公开了一组预测颅内动脉瘤稳定性的菌群标志物及其应用。所述菌群标志物为瘤胃球菌科(Ruminococc
