Question

The bacterium (Clostridium botulinum) that causes botulism is

• A. An obligate aerobe
• B. A facultative anaerobe
• C. An obligate anaerobe
• D. A facultative aerobe

Answer 1

The correct option is C An obligate anaerobe

Clostridium botulinum is the name of bacteria commonly found in soil all over the world. The bacteria are considered to be anaerobic, which means these organisms grow best in low or absent oxygen levels. Clostridium bacteria are gram-positive rod-shaped bacteria that form spores that allow the bacteria to survive in a dormant state until exposed to conditions that can support growth.

So, the correct answer is 'An obligate anaerobe'.
