Polysaccharides of Gram-Negative Bacteria
1961Publisher Summary This chapter discusses the polysaccharides of gram-negative bacteria. In Gram-negative bacteria, the general architecture of the outer layers of the cell seems to be consistent within the group. The cell wall is rarely exposed, but is generally covered by a somatic antigen’ that can be extracted as a protein-lipide-polysaccharide ...

Gram-negative bacteria are responsible for a broad array of infections in both the ambulatory and hospital settings. Urinary tract infections, otitis media, pneumonia, abdominal infections, and meningitis are among the common and serious diseases caused by these pathogens. Beta-lactams including penicillins, cephalosporins, monobactams, and carbapenems,

The Lipooligosaccharides of Pathogenic Gram-Negative Bacteria
Critical Reviews in Microbiology, 1996Lipooligosaccharides (LOSs) are the major glycolipids expressed on mucosal Gram-negative bacteria, including members of the genera Neisseria, Haemophilus, Bordetella, and Branhamella. They can also be expressed on some enteric bacteria such as Campylobacter jejuni and Campylobacter coli strains. LOS is analogous to the lipopolysaccharide (LPS) found in

Non-fermentative Gram-negative bacteria
International Journal of Antimicrobial Agents, 2007Over the past decade, non-fermenting Gram-negative bacteria have emerged as important opportunistic pathogens in the increasing population of patients who are immunocompromised by their disease or medical treatment. These bacteria are assisted by their ubiquitous distribution in the environment and have a propensity for multiple, intrinsic or acquired ...

Periplasmic enzymes in gram-negative bacteria
International Journal of Biochemistry, 1979Abstract 1. 1. In this article we have attempted to review the enzymatic component of the periplasmic space of gram-negative bacteria in terms of what constitutes a periplasmic enzyme, criteria for their localization, and their expression and functions in the intact cell. 2. 2.

Corneal Rings With Gram-Negative Bacteria
Archives of Ophthalmology, 1977Corneal rings have been described with corneal ulcerations caused by Gram-negative bacteria. Corneal rings were produced by intracorneal injections of viable Pseudomonas aeruginosa as well as heat-inactivated suspensions of Gram-negative bacteria (P aeruginosa and Escherichia coli) but not Gram-positive bacteria (Staphylococcus aureus) or Freund's ...

The Lysozyme Spectrum of the Gram-Negative Bacteria
Journal of Infectious Diseases, 1955containing lysozyme indicated that the enzyme is one of nature's defensive mechanisms. Lysozyme is currently associated with ulcerative conditions of the intestine. As a part of this syndrome, the role of lysozyme as it affects the ever-present gram-negative bacteria in the intestine is yet to be shown.

Multidrug resistance in Gram-negative bacteria
Current Opinion in Microbiology, 2001Broadly specific, so-called multidrug, efflux mechanisms are now known to contribute significantly to intrinsic and acquired multidrug resistance in a number of Gram-negative bacteria, and the boom in bacterial genomics has confirmed the distribution of these systems in all bacteria.

Endotoxins: Lipopolysaccharides of Gram-Negative Bacteria
2010Endotoxin refers lipopolysaccharide that constitutes the outer leaflet of the outer membrane of most Gram-negative bacteria. Lipopolysaccharide is comprised of a hydrophilic polysaccharide and a hydrophobic component known as lipid A which is responsible for the major bioactivity of endotoxin.
