MICROBIOLOGY

  • C. canimorsus (previously known as DF-2, dysgonic fermenter) and C. cynodegmi (previously known as DF-2 like organism) are facultatively anaerobic Gram-negative rods, part of normal oral flora of dogs and cats.
    • C. cynodegmi is considered less virulent than C. canimorsus.
    • Other Capnocytophaga species may be part of normal human oral flora or dental plaque, e.g., C. sputigena and C. gingivalis.
  • Organisms have a long, fusiform appearance on gram stain, making it distinctive enough to consider morphologic identification pending cx results.
  • Organisms considered fastidious by micro lab.
  • Most strains are resistant to polymyxin, fusidic acid, fosfomycin and trimethoprim.
