Classic Spotlight: Gram-Negative Bacteria Have Two Membranes.
The Danish microbiologist Hans Christian Gram developed a staining technique (1884) that classifies most bacteria into two large groups that are referred to eponymously, as Gram-positive and Gram-negative bacteria (1). His stain is still used in medical microbiology labs today, and because of its explanatory power, this classification is the most commonly used descriptor of a particular bacteri...
متن کاملGram-Negative Bacteria: The cell Membranes
This chapter presents a brief outline of our current knowledge of the structures of the bounding membranes (the inner and the outer membranes and the intermediate periplasmic layer) of a Gram-negative bacterial cell. Also the structure and chemical composition of the outer membrane vesicles (OMVs) originating from the surface of these bacteria including their proteomic profile, as obtained main...

متن کاملBiogenesis of outer membranes in Gram-negative bacteria.
The outer membrane, an essential organelle of Gram-negative bacteria, is composed of four major components: lipopolysaccharide, phospholipids, beta-barrel proteins, and lipoproteins. The mechanisms underlying the transport of these components to outer membranes are currently under extensive examination. Among them, the sorting of lipoproteins to the outer membrane of Escherichia coli has been c...
متن کاملIsolation of Gram-negative Bacteria
Three different areas -hospital, food-handling establishments and human dwellings, were surveyed for pathogenic gram-negative bacteria carried on the cuticles of cockroaches. Fifty species of bacteria were identified from all cockroaches. Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii and Enterobacter cloacae were the most frequently found. Pathogenic and potentially pathogenic b...
