2
Scientific Name

• Clostridium tetani

3
Classification

• Strain There are currently eleven identified
  strains of Clostridium tetani. (but I could not
  find any specific strains)
• Shape/Arrangement Bacillus (rod shaped),
  Straphylo.

4
Metabolism

• Clostridium tetani is an anaerobic bacterium

5
Habitat

• Clostridium tetani colonizes the intestinal tract
  in humans and animals, but is also found in soil.

6
Adaptations

• Clostridium tetani bacteria feature two primary
  life stages, sporular and vegetative. The
  vegetative stage is highly anaerobic and is
  unable to survive any exposure to oxygen. On the
  other hand, the sporular form is quite hardy and
  can withstand oxygen and other environmental
  factors.
• Infecting wounds Clostridium tetani parasitizes
  its host using extracellular excretions to
  degrade surrounding organic material for
  fermentation.
• As with the majority of bacteria, Clostridium
  tetani reproduces asexually. Clostridium tetanis
  growth is exponential.

7
Gram Negative or Positive, Endotoxin or Exotoxin

• Clostridium tetani is gram positive which is an
  exotoxin.

8
Function/Impact on the Environment

• Clostridium tentani produces a potent biological
  toxin, called tetanospasmin, and is the cause of
  tetanus, a disease characterized by painful
  muscular spasms that may lead to respiratory
  failure.
