Morphology of Clostridium perfringens

  1. Clostridium perfringens is large rectangular gram positive bacilli with rounded or truncated ends.
  2. It is pleomorphic with straight or curved rods.
  3. Size is about 3-8 µm X 0.4-1.2 µm.
  4. It is capsulated, non-motile and non-flagellated pathogenic bacteria.
  5. It contains spores with central or sub-terminal spores but spores are rarely seen.
  6. Endospores are able to survive long periods of exposure to air and other adverse environmental conditions.
  7. Spores are wider than bacillary body, giving bacillus a swollen appearance resembling spindle.
  8. It is heat resistant anaerobic bacterium.
  9. It have a protective thick cell wall made up of peptidoglycan.
  10. It is able to glide across surface because their bodies are lined with filaments from end-to-end.

Genome Structure

  • Single circular chromosome
  • 6 million base pair
  • GC content from 24 to 55%
  • Contains 10 rRNA gene and 96 tRNA genes.
