"Gram-positive" Pronounce,Meaning And Examples

"Gram-positive" Meaning

Gram-positive bacteria are a group of bacteria that have a thick peptidoglycan layer in their cell walls, giving them a positive result when tested with Gram's stain. This test differentiates bacteria into two main groups: Gram-positive and Gram-negative. Gram-positive bacteria, such as Staphylococcus aureus and Bacillus subtilis, have a specific structure of their cell walls that allows them to retain the Gram stain, appearing pink or purple under a microscope.
