🧪 Answer Reveal: Recall Poll Question
Question:
Which characteristic helps differentiate Bacillus cereus from Bacillus anthracis?
✅ Correct Answer: C) Motility
👏 Thanks to everyone who voted! 🎉
🧠 Explanation:
One of the easiest ways to distinguish these two organisms in the laboratory is motility.
✔ Bacillus cereus = Motile 🏃♂️
✔ Bacillus anthracis = Non-motile 🛑
Although both are Gram-positive, spore-forming rods and catalase positive, motility is a key test used to tell them apart.
🔬 Why not the other options?
A) Gram-positive rods ❌
• Both organisms are Gram-positive rods.
B) Spore formation ❌
• Both species produce endospores.
D) Catalase positivity ❌
• Both are catalase positive.
None of these characteristics differentiate one from the other.
💡 Quick Recall Tip:
🦠 B. cereus = Cruises around = Motile 🚢
🦠 B. anthracis = Anchored = Non-motile ⚓
🔥 High-Yield ASCP Clue:
When comparing Bacillus anthracis and Bacillus cereus, remember:
✅ Both are:
- Gram-positive rods
- Spore formers
- Catalase positive
⭐ The distinguishing feature is motility:
- B. cereus = Motile
- B. anthracis = Non-motile
