Question

Match List-I with List-II

List-I (Colony characters)	List-II (Name of specific bacteria)
(A) Swarming growth on Nutrient agar	(I) Hemophillus
(B) Metallic sheen on Eosin Methylene Blue agar	(II) Pseudomonas
(C) Green pigment on Nutrient agar	(III) Proteus
(D) Growth on Chocolate agar	(IV) Escherichia coli

• (A) - (III), (B) - (IV), (C) - (II), (D) - (I)
• (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

Associate these unique bacterial characteristics:
- *Proteus* \(\rightarrow\) Swarming (always moves like a wave).
- *E. coli* on EMB \(\rightarrow\) Metallic green sheen (very classic board question).
- *Pseudomonas* \(\rightarrow\) Green pigment (produces pyocyanin).
- *Haemophilus* \(\rightarrow\) Chocolate agar (fastidious, requires lysed RBC factors).

Answer 1
