In this video, we observe Bacillus cereus, an important foodborne pathogen, growing on blood agar.

🔬 Colony Morphology
- Good growth
- Large gray-white colonies
- Beta-hemolysis (clear zone around colonies)
- Rough texture with irregular edges
- Characteristic ground-glass appearance
- May show spreading growth

🧪 Key Identification Tests
✔ Gram-positive large rods
✔ Spore-forming (central or subterminal spores)
✔ Motile
✔ Catalase positive
✔ Lecithinase positive (on egg yolk agar)

Bacillus cereus is associated with food poisoning (emetic & diarrheal types) and can also cause opportunistic infections.
