Question

Quizplus · Accepted Answer

Gram staining is a method used to differentiate bacterial species into two large groups (Gram-positive and Gram-negative) based on the physical properties of their cell walls. This differentiation helps in guiding antibiotic therapy, as Gram-positive and Gram-negative bacteria can respond differently to antibiotics. It does not directly speed up culturing processes or identify tuberculosis organisms, which are better identified using acid-fast staining.
