unmasking of bacteriophage mu lipopolysaccharide receptors in salmonella enteritidis confers sensitivity to mu and permits mu mutagenesis.the human pathogen salmonella enteritidis 3b was found to be highly resistant to phage p22 and mu derivatives. the mu sensitivity (musa1) allele from salmonella typhimurium could be transferred to s. enteritidis 3b at low frequency by cotransduction with hisg::tn10. sensitivity to mu resulted in a large reduction in the number of lipopolysaccharide core-region oligosaccharides that were substituted with o-antigen polysaccharide. the residual high-molecular-weight lipopolysaccharide appeared to b ...19882963805
[characteristics of k+ uptake in s. enteritidis bacteria].bacterial salmonella enteritidis var. issatchenko in media without exogenic energy source uptakes k+ in one step with km 2.1 mm and vmax 0.08 mm min-1/10(12) cells. this k+ uptake does not depend on ph and osmotic shock and is not inhibited by dcc. endogenic energy source (glucose) leads to k+ uptake with km 2.8 mm and vmax 0.10 mm min-1/10(12) cells, and secretion of h+. the ratio of the dcc-sensitive fluxes of h+ to k+ equals 2. arsenate and protonophores depress the k+ uptake. valinomycin dec ...19882898951

endotoxin causes neutrophil-independent oxidative stress in rats.endotoxin-induced oxidative stress is investigated in rats by measuring changes in plasma and lung tissue levels of glutathione disulfide (gssg) using a modified enzymatic assay that allows simultaneous measurement of up to 80 samples. salmonella enteritidis endotoxin (2 and 20 mg/kg) acutely increased both plasma reduced glutathione and gssg with a rise in the ratio of gssg to total glutathione. this increase in gssg was enhanced by pretreatment with 1,3-bis(2-chloroethyl)1-nitrosourea (bcnu), ...19883042743
cloning and expression of a salmonella enteritidis fimbrin gene in escherichia coli.a gene bank of dna from a human isolate of salmonella enteritidis was constructed in the cosmid phc79 in escherichia coli hb101. five clones containing 35- to 45-kilobase inserts of s. enteritidis dna reacted in colony immunoblot assays with a polyclonal antiserum prepared against purified s. enteritidis fimbriae. electron microscopy showed that none of the five fimbrin-producing clones produced fimbriae, yet radioimmunoprecipitation and sodium dodecyl sulfate-polyacrylamide gel electrophoresis ...19882900832
toward a population genetic analysis of salmonella: genetic diversity and relationships among strains of serotypes s. choleraesuis, s. derby, s. dublin, s. enteritidis, s. heidelberg, s. infantis, s. newport, and s. typhimurium.variation in the chromosomal genomes of 1527 isolates of eight common serotypes (o and h antigen profiles) of salmonella was assessed by analysis of electrophoretically demonstrable allelic polymorphism at 23 metabolic enzyme loci. seventy-one distinctive electrophoretic types, representing multilocus genotypes, were identified. a basically clonal population structure was indicated by the presence of strong linkage disequilibrium among enzyme loci, the association of each serotype with a relativ ...19883051004

effects of the specific platelet-activating factor antagonists, bn 52021 and bn 52063, on various experimental gastrointestinal ulcerations.platelet-activating factor (paf) has been shown recently to induce gastrointestinal damage similar to that evoked by endotoxin, suggesting that the autacoid could be implicated in other types of gastrointestinal damage. thus, the effects of bn 52021 and bn 52063, two specific paf antagonists, were investigated in various experimental models of gastrointestinal damage in rats. bn 52021 and bn 52063, markedly reduced both the paf- and endotoxin-induced alterations of the mucosa, suggesting a role ...19883046952
left ventricular function during chronic endotoxemia in swine.cardiac performance was studied in 15 chronically instrumented awake pigs during chronic endotoxemia (cet) induced by intravenous infusion of low doses of endotoxin. we sought to test the hypothesis that left ventricular inotropic state was depressed during the stage of chronic endotoxemia when cardiac output, heart rate, and left ventricular systolic pressures are elevated, termed "hyperdynamic sepsis". left ventricular pressure, internal short axis diameter (sax), pulmonary artery blood flow, ...19883344822
mechanism of action of physical antipyresis in the rat.to study the mechanism of action of physical antipyresis, core temperature was measured in two groups of rats in which heat loss was increased by cold exposure and by cooling an inferior cava heat exchanger, respectively, both before and after infection with salmonella enteritidis. cold exposure did not influence core temperature. on the other hand, cooling the heat exchanger caused a fall in core temperature of approximately 0.7 degree c, to 37 degrees c in normothermia and to 38.5 degrees c 24 ...19883366729
optimal cefotaxime dosing for gram-negative bacteremia: effective trough serum bactericidal titers and drug concentrations 8 and 12 hr after 1- or 2-gm infusions.thirteen adult patients (47-81 yr) with gram-negative bacteremia and normal (less than or equal to 1.5 mg/dl) serum creatinines were treated with 1 or 2 gm of cefotaxime every 8 or 12 hr. the infecting organisms were escherichia coli (9 strains), klebsiella pneumoniae (2 strains), and one isolate of salmonella enteritidis and serratia marcescens. all patients recovered without any serious sequelae. the range of mics for cefotaxime and desacetyl-cefotaxime were 0.015-0.25 micrograms/ml and 0.015- ...19883383550
