Comparison of Biological and Immunological Characterization of Lipopolysaccharides From Brucella abortus RB51 and S19
BACKGROUND Brucella abortus RB51 is a rough stable mutant strain, which has been widely used as a live vaccine for prevention of brucellosis in cattle instead of B. abortus strain S19. B. abortus lipopolysaccharide (LPS) has unique properties in comparison to other bacterial LPS. OBJECTIVES In the current study, two types of LPS, smooth (S-LPS) and rough (R-LPS) were purified from B. abortus ...
متن کاملcomparison of biological and immunological characterization of lipopolysaccharides from brucella abortus rb51 and s19
conclusions purified lps can be considered as a safe adjuvant and can be used as a component in prophylactic and therapeutic vaccines targeting infectious disease, cancer and allergies. results biochemical analysis data and sds-page profile showed that the chemical nature of s19 lps is different from rb51 lps. both s and r-lps induce an immune response. t-cell immune response induced by both s ...
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...
متن کاملBrucella abortus endocarditis.
T HE purpose of this report is to describe the successful treatment of a case of bacterial endocarditis due to Brucella abortus. As far as I have been able to discover at the date of writing, no successfully treated case of this disease has been reported previously, with the exception of a case of mixed bacterial endocarditis presented in 1954 by Quinn and Brown.' A second case of treated Br. a...
متن کاملRegulation of Brucella abortus catalase.
All aerobic organisms have mechanisms that protect against oxidative compounds. Catalase, peroxidase, superoxide dismutase, glutathione, and thioredoxin are widely distributed in many taxa and constitute elements of a nearly ubiquitous antioxidant metabolic strategy. Interestingly, the regulatory mechanisms that control these elements are rather different depending on the nature of the oxidativ...
