TABLE 3.
Summary of taxa implicated in periodontal diagnoses as well as anxiety disorders, depressive disorders, and trauma- and stressor-related disorders.
| Taxa | Results | References |
|---|---|---|
| Prevotella | Prevotella intermedia, and Prevotella nigrescens was correlated with diseased periodontal tissues | (100, 101) |
| Negatively associated with distress and negatively associated with inflammatory markers and part of a consortium of taxa that could accurately predict distress and inflammation (saliva samples) | (102) | |
| Decreased in schizophrenia and mania cohorts (oropharyngeal samples) | (103) | |
| Neisseria | Decreased in schizophrenia and mania cohorts (oropharyngeal samples) | (103) |
| Neisseriales order was positively associated with CRP; Neisseriaceae family was positively associated with CRP and cortisol (saliva samples) | (104) | |
| Fusobacterium | Fusobacterium nucleatum was correlated with diseased periodontal tissues | (105) |
| Positively correlated with depression (saliva samples) | (104) | |
| Leptotrichia | Associated with persistent generalized periodontal disease | (105) |
| Positively correlated with depression and cortisol levels (saliva samples) | (104) | |
| Positively associated with distress and host inflammation (saliva samples) | (102) | |
| Streptococcus | Higher proportions in patients successfully treated using active periodontal treatment (saliva samples) | (105) |
| A Streptococcus taxon was associated with cortisol, anxiety and depression | (104) | |
| Streptococcus taxa could accurately predict distress | (102) | |
| Selenomonas | Associated with persistent generalized periodontal disease | (105) |
| Implicated to be involved in the pathogenesis of periodontitis | (106–108) | |
| A Streptococcus taxon was associated with cortisol, anxiety and depression | (104) |
CRP, C-reactive protein.
