Corneal Rings With Gram-Negative Bacteria

Archives of Ophthalmology, 1977
Corneal 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 Lipooligosaccharides of Pathogenic Gram-Negative Bacteria

Critical Reviews in Microbiology, 1996
Lipooligosaccharides (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, 2007
Over 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 ...

The Lysozyme Spectrum of the Gram-Negative Bacteria

Journal of Infectious Diseases, 1955
containing 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.

Increasing threat of Gram-negative bacteria

Critical Care Medicine, 2001
The widespread use of broad-spectrum antibiotics has led to emergence of antibiotic-resistant strains of many Gram-negative organisms. This problem is particularly serious in critically ill patients, especially those with ventilator-associated pneumonia.

Endotoxins: Lipopolysaccharides of Gram-Negative Bacteria

2010
Endotoxin 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.

Gram-Negative Bacteria

2009
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,

Fever and the control of gram-negative bacteria

Research in Microbiology, 1994
Although it seems obvious that fever has some important general adaptive value, it is still not clear by what means this function is manifested. One postulate is that febrile conditions result in the sequestration of soluble iron, effectively starving some pathogens of that essential nutrient.

The Effects of Lactoferrin on Gram-Negative Bacteria

1994
Lactoferrin is an iron-binding protein found in human mucosal secretions as well as the specific granules of polymorphonuclear leukocytes. A variety of functions have been ascribed to the protein, and it appears to contribute to antimicrobial host defense.
