Question

A most widely employed microscopic staining method in bacteriology:

• A. Acid staining
• B. Cell staining
• C. Gram staining
• D. Safranin staining

Hint:

Gram staining differentiates bacteria into Gram-positive and Gram-negative groups.

Answer 1

The Correct Option is C

Concept:
Staining techniques are used in bacteriology to observe and differentiate bacteria under microscope.

Step 1: Identify the common staining method.
Gram staining is the most widely used differential staining method in bacteriology. \[ \text{Gram staining} \rightarrow \text{bacterial classification} \]

Step 2: Importance of Gram staining.
It divides bacteria into two groups: \[ \text{Gram-positive bacteria} \] and \[ \text{Gram-negative bacteria} \]

Step 3: Final answer.
Therefore, the most widely employed microscopic staining method in bacteriology is Gram staining. \[ \therefore \text{Correct Answer is (C)} \]
