Definition
- Noun:
- A species of anaerobic, spore-forming bacterium: Clostridium botulinum is a rod-shaped bacterium that thrives in environments without oxygen and produces highly resistant spores.
- The producer of botulinum toxin: This bacterium synthesizes a potent neurotoxin called botulin, which is the causative agent of the serious illness botulism.
Usage
The term Clostridium botulinum is used primarily in scientific, medical, and public health contexts to identify the specific bacterial species responsible for botulism food poisoning and wound botulism. - It functions as a singular noun, though it represents a species comprising many individual cells. - It is often referred to simply as C. botulinum in technical writing after its first full mention.
Examples
- Scientific Context:
- The canned food was recalled after tests confirmed the presence of Clostridium botulinum.
