Radioprotective Properties of Detoxified Lipid A from Salmonella minnesota R595

Radiation Research, 1986
In the past, the toxicity of bacterial lipopolysaccharide (LPS) or its principal bioactive component, lipid A, has detracted from their potential use as radioprotectants. Recently, a relatively nontoxic monophosphoryl Lipid A (LAM) that retains many of the immunobiologic properties of LPS has been isolated from a polysaccharide deficient Re mutant ...

Salmonella Recovery from Three Turkey-Processing Plants in Minnesota

Avian Diseases, 1973
Three turkey-producing plants at different locations in Minnesota were surveyed in the fall and winter of 1971-72. The results showed: 1) All plants but one were clean before the day's operation began; 2) salmonella concentrations were greatest on defeathering machines; 3) the serotype of salmonella spread throughout the plant was the same as the one(s)

Polymorphism of Crystals of Salmonella minnesota Re and Ra Lipopolysaccharides

Microbiology and Immunology, 1993
AbstractSalmonella minnesota Re and Ra lipopolysaccharides (LPSs) formed three‐dimensional crystals when they were precipitated by the addition of 2 volumes of 95% ethanol containing 375 mM MgCl2 and incubated in 70% ethanol containing 250 mM MgCl2 at 4 C.

Heterogeneity and Biological Activity of Endotoxic Glycolipid from Salmonella minnesota R595

Journal of Infectious Diseases, 1973
The endotoxic glycolipid of Salmonella minnesota R595 was extracted either by the phenol-water method (GL) or directly with chloroform-methanol (GL-DE). Both glycolipids were soluble in chloroform-methanol (4:1). The yield of GL-DE was higher than that of GL.

Immunization with Rough Mutants of Salmonella minnesota: Initial Studies in Human Subjects

Journal of Infectious Diseases, 1988
Vaccines prepared from unheated and boiled, acetone-precipitated Salmonella minnesota R595 (Re chemotype mutant) were administered subcutaneously to 122 healthy volunteers. Titers of antibody to Re lipopolysaccharide, the basal core structure of endotoxin, as measured by indirect hemagglutination, rose in a dose-responsive fashion after immunization ...

Influence of temperature on growth of lipopolysaccharide-deficient (rough) mutants of Salmonella typhimurium and Salmonella minnesota

Canadian Journal of Microbiology, 1976
Smooth strains of Salmonella typhimurium and S. minnesota, and chemotypes Ra, Rb, and Rc, which are deficient in lipopolysaccharide components of the somatic side chains and outer core region, grow normally on nutrient agar and nutrient broth up to 45 °C.

Further Characterization of Monoclonal Antibodies to Lipopolysaccharide of Salmonella Minnesota Strain R595

1990
We have shown here that despite the use of monoclonal antibodies with well-defined epitope-specificities, and despite testing them in the most simple animal model available (i.e., mixing of homologous LPS with Mab prior to injection), we are not yet able to explain why some of the antibodies were effective and others not.

Studies of a receptor for FP3-phage in Salmonella minnesota R595.

Archivum immunologiae et therapiae experimentalis, 1979
The adsorption rate constant of the phage FP3 to sensitive S. minnesota R595 strain was used to evaluate the inactivating capacity towards phage FP3 exhibited by isolated glycolipid and free lipid A. The results suggest that phage FP3 receptor is localized in the glycolipid structure. Phage FP3 is not adsorbed on the other Re mutant cells, Proteus R45,

Studies on a receptor for pyocin in a R mutant of Salmonella minnesota.

Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Erste Abteilung Originale. Reihe A: Medizinische Mikrobiologie und Parasitologie, 1979
Lipopolysaccharide (LPS) isolated from the pyocin sensitive R form strain of Salmonella minnesota F6 (chemotype Rd1) inhibited the activity of bacteriophage tail-like pyocin P1 whereas no inhibition occurred with LPS prepared from the pyocin resistant S form of S. minnesota.
