The Gram stain classifies bacteria according to whether they retain crystal violet stain (gram-positive—blue) or not (gram-negative—red) and highlights cell morphology (eg, bacilli, cocci) and cell arrangement (eg, clumps, chains, diploids). Such characteristics can direct antibiotic therapy pending definitive identification. Finding a mixture of microorganisms with multiple morphologies and staining characteristics on Gram stain suggests a polymicrobial bacterial infection. To do a Gram stain, technicians heat-fix specimen material to a slide and stain it by sequential exposure to Gram crystal violet, iodine, decolorizer, and counterstain (typically safranin)..
