LIPID A and BACTERIAL LIPOPOLYSACCHARIDES
1. Structure and Occurrence The envelope of Gram-negative bacteria, including those of human pathogens such as Escherichia coli and Salmonella enterica, is composed of two distinct lipid membranes: an inner membrane, consisting of glycerophospholipids, and a highly distinctive outer membrane. The latter is an asymmetric bilayer, the outer leaflet of which in most species consists predominantly ...
متن کاملBiological activities of lipopolysaccharides and lipid A from Rhodospirillaceae.
The lipopolysaccharides and free lipid A from several strains of Rhodospirillaceae were assayed comparatively with those of Enterobacteriaceae in a number of biological tests. Free lipid A's from Rhodopseudomonas gelatinosa and Rhodospirillum tenue exhibited strong serological cross-reactions with each other and with free lipid A from Salmonella. Lipid A's from Rhodopseudomonas viridis and Rhod...
متن کاملStudies of lipid A fractions from the lipopolysaccharides of Pseudomonas aeruginosa and Pseudomonas alcaligenes.
Lipid A fractions from Pseudomonas aeruginosa and Pseudomonas alcaligenes have similar compositions and structural features. By means of hydrazinolysis of the parent lipopolysaccharides and partial hydrolysis of the deacylation products, it was established that both lipids are derived from the beta-(1-->6)-linked disaccharide of glucosamine. Phosphorylated derivatives of the disaccharide from P...
متن کاملStudies on lipopolysaccharides isolated from strains of Neisseria gonorrhoeae.
Lipopolysaccharides, extracted by phenol-water from five strains fo Neisseria gonorrhoeae, were purified by treatment with ribonuclease followed by multiple washes. These preparations were fatal to mice when administered in submicrogram amounts with actinomycin D, the LD50 values varying from 4 to 16 mug/kg. Analyses showed that all preparations contained glucose, galactose, glucosamine, heptos...
متن کاملEffects of Lipopolysaccharides (LPS) of Yersinia ruckeri on Immune Response in Rainbow Trout (Oncorhynchus mykiss) by Intraperitoneal and Oral Administration
BACKGROUND: Recently, the researches about herbal medicines as substitutes for chemical drugs have risen in number. OBJECTIVES: To add more aspects to this research area, this study evaluated the changes in biochemical factors of the blood serum due to the consumption of Thymus daenensis extract and the effect of the period of its consumption int...
