Physical differences amp clinical signifigance Figure 48b Gram positive bacteria Gramnegative bacteria Figure 48a GramPositive cell walls Teichoic acids Lipoteichoic acid links to plasma membrane. Gram Stain Reaction. The Gram stain reaction, named after the Danish bacteriologist Hans Christian Gram, was originally devised in 1882.. Gram staining is based on the ability of the bacterial cell wall to retain the crystal violet dye. . Bacteria . One of our kingdoms. Bacteria. Bacteria are minute microscopic prokaryotes.
