Occurrence of quinovosamine in lipopolysaccharides of Brucella species.
Lipopolysaccharides obtained from Brucella abortus, B. melitensis, and B. suis, but not B. canis, were found to contain amino sugars identified as glucosamine and quinovosamine by cation exchange and thin-layer cellulose chromatography and ninhydrin degradation.
متن کاملImmunochemical characterization of Brucella lipopolysaccharides and polysaccharides.
Purified lipopolysaccharide (LPS) extracted with phenol-water from smooth Brucella abortus was hydrolyzed with 1% acetic acid at 100 degrees C. The degraded polysaccharide (AH) released gave reactions of identity with the native polysaccharide hapten (NH) in phenol-water- or trichloroacetic acid-extracted endotoxin preparations of B. abortus and with the polysaccharide (poly B) extracted by tri...
متن کاملImmunochemical characterization of rough Brucella lipopolysaccharides.
Lipopolysaccharides (LPS) were extracted from rough strains of Brucella abortus and Brucella melitensis and from strains of the naturally occurring rough species Brucella ovis and Brucella canis. Brucella rough lipopolysaccharides (R-LPS) were readily distinguished from Brucella smooth lipopolysaccharides (S-LPS) and enterobacterial R-LPS, by their chemical, physical, and serological characteri...
متن کاملLipopolysaccharides of Brucella abortus and Brucella melitensis induce nitric oxide synthesis in rat peritoneal macrophages.
Smooth lipopolysaccharide (S-LPS) and lipid A of Brucella abortus and Brucella melitensis induced the production of nitric oxide (NO) by rat adherent peritoneal cells, but they induced lower levels of production of NO than Escherichia coli LPS. The participation of the inducible isoform of NO synthase (iNOS) was confirmed by the finding of an increased expression of both iNOS mRNA and iNOS prot...

چکیده پایان نامه (شامل خلاصه، اهداف، روش های اجرا و نتایج به دست آمده): کار جمع آوری گو یش های محلی در سال های اخیر شتاب امیدوار کننده ای به خود گرفته است. شاید از بارزترین اهداف جمع آوری گویش های مختلف، ثبت و ضبط آن، جلوگیری از نابودی و مهمتر از همه حل مشکلات دستوری زبان رسمی باشد. دقت در فرآیند های زبانی گویش های محلی نوع ارتباط مردم نواحی مختلف با پیرامون نشان را به ما نشان خواهد داد. از س...
