The Gram stain is the most useful stain in helping clinicians to decide which antibiotic to prescribe for a bacterial infection. This is because it helps to differentiate bacterial species based on their cell wall composition, which in turn determines their susceptibility to certain antibiotics. Gram-positive bacteria, which have a thick peptidoglycan layer in their cell wall, are more susceptible to antibiotics that target this layer, such as penicillin. Gram-negative bacteria, which have a thinner peptidoglycan layer and an outer membrane, are less susceptible to these antibiotics but can be targeted by others, such as cephalosporins or tetracyclines.
