Gram-negative bacteria (or negibacteria) is a bacteria that

not retain crystal violet dye in the Gram staining protocol.

Characteristics of Gram-negative cell wall structure

Gram-positive and-negative bacteria mainly

differ in their cell wall structure. The following characteristics appear Gram-negative bacteria

consists of lipid, the major polysaccharides, as well as the antigen)
