Tests for bacterial motility

• Used to detect bacteria that are motile
• Tube motility
  • Stab an inoculum down into a tube with semisolid agar
  • Check at intervals for diffuse, fuzzy growth that appears outside of the stab line
• Wet prep
  • Put a drop of inoculum in distilled water and check under a microscope
  • Can compare to a drop of peptone water to identify Vibrio (motile in peptone water, not distilled)
