  1. Morphology/Growth

    Three periplasmic flagella (axial filaments);Not cultured in artificial media; Grown in rabbits.
    Treponema pallidum ssp. pallidum
  2. Morphology/Growth

    Endoflagella; Endemic and epidemic forms
    Borrelia hermsii /B. recurrentis
  3. Morphology/Growth7-20 endoflagella; Microaerophilic; Grown in BSK (Barbour-Stoenner-Kelley) broth
    Borrelia burgdorferi
  4. Antigenic Structure

    No LPS; outer membrane lipoproteins; hyaluronidase; fibronectin

    No extracellular virulence-producing toxins have been identified
    Treponema pallidum ssp. pallidum
  5. Diagnosed using darkfield microscopy of lymph node aspirate

    Immunoserology Confirmatory Tests include: FTA-ABS

    Other tests include: TP-PA test
