Periodontal pathogen

Periodontal pathogens are bacteria that have been shown to significantly contribute to periodontitis.

Although approximately 700 bacterial species have been identified in the oral cavity and nearly 300 species have been cultured and found to contribute to the biofilm of 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:

• 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.
