• Gram reaction
• Shape and arrangement of organism

Discussion (20 points)

• Explain how your organism’s tests differed from the other gram – or +
• Write at least two paragraph about the significance of your organism
  • g. Diseases it causes, Interesting facts etc. (The information can be collected from sources such as your text book, lab manual, or internet.)

References (5 points).
