Gram negative bacteria infections

Patent Pending ram-negative bacteria are a class of bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation,[1] making positive identification possible. The thin peptidoglycan layer of their cell wall is sandwiched between an inner cell membrane and a bacterial outer membrane. In Gram staining, the outer lipid-based membrane of gram-negative bacteria is removed by an alcohol solution.
