Structure / Classification

• Gram negative
• Curved bacilli
• Long flagellum
• A delta proteobacteria
• Exist independently

3
Habitat / Metabolism

• Found in the ocean and fresh water
• 6C to 37C
• Chemoheterotroph
• Also found in land habitats and the intestines of
  mammals
• Eat gram negative bacteria that often cause
  disease in plants, animals, and humans
• It is both aerobic and anaerobic but it works
  faster in an aerobic environment

4
Adaptations

• Two phases of life, attack stage and growth stage
• Very small 0.2 to 0.5 micrometers x 0.5 to 1.4
  micrometers
• Can move 100 cell lengths per second
• Grows inside the prey cell and can increase its
  length up to 20 times
• Cell then bursts and the cycle repeats

Wow

• Used to fight food borne illness and can destroy
  90 of an E. Coli colony in an hour
• Moves at a speed that is equivalent to a human
  running at 600 km/hr
• Bore into the prey cell at over 100 rotations per
  second
