Periodontal pathogen
Periodontal pathogens are
periodontitis
.
bacteriophages—are most common in the oral cavity. Viral roles in the progression of periodontal disease as of 2017 remains poorly explored.[1]
Although approximately 700 bacterial species have been identified in the
periodontal pocket, there is a much smaller number of species that have been shown to be more closely related to the initial incidence and continued persistence of periodontitis, including:[2]
- Aggregatibacter actinomycetemcomitans
- Porphyromonas gingivalis
- Tannerella forsythia (formerly Bacteroides forsythus)
- Treponema denticola
- Fusobacterium nucleatum
- Prevotella intermedia
- Prevotella nigrescens
- Eikenella corrodens
- Eubacterium nodatum
- Parvimonas micra (formerly Peptostreptococcus micros or Micromonas micros)
- Streptococcus intermedius
- Campylobacter rectus
- Capnocytophaga sp.
A number of types of fungi, especially Candida spp., also play a smaller but not insignificant role in periodontal disease.[3]
