The Gram stain is the most useful stain in helping clinicians to decide which antibiotic to prescribe for a bacterial infection. It differentiates bacteria into two major groups; Gram-positive and Gram-negative, based on the differences in the composition of their cell walls. Gram-positive bacteria stain purple/blue, while Gram-negative bacteria stain red/pink. This information is essential as different types of bacteria may respond differently to antibiotics, and knowing the Gram status can guide the choice of appropriate antibiotics.
