The association of bacterial infection with intracranial aneurysm disease

The human body abounds in micro-organisms that maintain the vital balance of the internal ecosystem. Though it is well known that several benefit the human body while others are linked to disease, how the microbiota affects the pathology of intra-cranial aneurysms is an interesting arena that still requires exploration. Studies have suggested possible association between the excess of bacteria, such as those causing gingivitis, as well the deficit of bacteria, such as loss of gut flora due to antibiotics, to intracranial aneurysms and their subsequent behavior. The authors review existing literature on the subject and outline the scope for further research on the subject.
