Pathophysiology

• 6 species cause disease in humans:

  • A. israelii
  • A. Naeslundii
  • A. odontolyticus
  • A. viscosus
  • A. Meyeri
  • A. gerencseriae

• Gram positive filamentous rod
• Sulfur Granules
• Actinomyces from within, Nocardia from without
• Generally low pathogenicity and cause disease only in the setting of antecedent tissue injury
