What is haemophilus influenzae gram stain?
Gram stain is a method of staining. Through this way, bacterial species are distinguished and classified into two large groups (gram-positive and gram-negative).
- Gram-positive bacteria retain the crystal violet dye, and thus are stained violet.
- Gram-negative bacteria are stained a pink color.
Haemophilus influenzae is a gram-negative bacterium, thereby showing a pink color after gram stained.
