Clostridium perfringens type C
Introduction
Classification
Taxonomy
- Kingdom: bacteria.
- Phylum: firmicutes.
- Class: clostridia.
- Order: clostridiales.
- Family: clostridiaceae.
- Genus: clostridium.
- Species: C. perfringens.
Etymology
- Gk: Clostridium: klōstēr - a spindle. L:perforare- to pierce.
Distribution
- Worldwide distribution.
- Found in the soil, decaying vegetation, marine sediments and gastrointestinal tract of animals.
Significance
- Characterized by the production of exotoxins (some of which cause enterotoxemias).
- There are five toxinotypes types (A, B, C, D and E) which produce one or more of the following toxins, alpha (CPA), beta (CPB), epsilon (EXT) and iota (IXT). Some other toxins are also produced but they are not used in the classification of this pathogen.
- Types B and C are relevant in cattle causing enteritides, dysentery, toxemia, death in calves and enterotoxemia (type C) in adult cattle.
- Type D is less frequently reported in cattle.
- There have also been reports of type A being associated with hemorrhagic bowel, bloody gut, or jejunal hemorrhage syndrome in dairy cows.
