modulation of endotoxin lethality in mice by hydrazine sulfate.although the precise mechanism of endotoxin lethality has yet to be defined, it is well recognized that the amount of hepatic phosphoenolpyruvate carboxykinase is reproducibly and significantly reduced after challenge with endotoxin. hydrazine has been shown to be a specific inhibitor of gluconeogenesis, causing a metabolic crossover at the step catalyzed by phosphoenolpyruvate carboxykinase. more recently, it has also been shown that hydrazine sulfate may be of potential therapeutic value again ...19892731984
bacterial culture of blood from critically ill dogs and cats: 100 cases (1985-1987).of 100 critically ill dogs and cats, 49 (39 dogs, 10 cats) had bacteremia. gram-negative bacilli were the most common isolates from the bloodstream of dogs with bacteremia (46%), and gram-positive cocci and anaerobic bacteria were isolated from 36% and 31% of positive cultures, respectively; 15% of positive cultures were polymicrobial. in cats, gram-negative bacilli (especially salmonella enteritidis) and anaerobic bacteria were the most common isolates, and 30% of positive cultures were polymic ...19892759883
alterations in plasma levels and complexing of gc (vitamin d-binding protein) in rats with endotoxic shock.septic shock is known to involve increased metabolism of arachidonic acid and generation of certain eicosanoids. recently, a new extracellular pool of unsaturated fatty acids including arachidonate has been found in relation to group-specific component (gc), a vitamin d-binding plasma protein that sequesters monomeric g-actin. since complexing with g-actin displaces fatty acids, possible alterations in plasma levels of gc and extent of complexing were sought in serial samples obtained from rats ...19892766482

[rotavirus infection in the older child and adult].rotaviruses were detected in 1.3% of more than 10,000 stool samples from children--older than 6 years--and adults. beside rotaviruses the main enteropathogenic agents found were salmonellae (6.3%) and campylobacter jejuni/coli (1.7%). similar as the rotavirus infection of infants, in adults symptoms and signs were nearly the same except that the disease was not so severe. a correlation of the rotavirus infection with certain behaviour or eating habits was not found.19872830184
pharmacokinetic and in vivo studies with azithromycin (cp-62,993), a new macrolide with an extended half-life and excellent tissue distribution.azithromycin (cp-62,993), a new acid-stable 15-membered-ring macrolide, was well absorbed following oral administration in mice, rats, dogs, and cynomolgus monkeys. this compound exhibited a uniformly long elimination half-life and was distributed exceptionally well into all tissues. this extravascular penetration of azithromycin was demonstrated by tissue/plasma area-under-the-curve ratios ranging from 13.6 to 137 compared with ratios for erythromycin of 3.1 to 11.6. the significance of these p ...19872830841
effect of bacterial endotoxin on lipoxygenase and cyclo-oxygenase metabolites by rat neutrophils and correlation with cellular functional parameters.the effect of salmonella enteritidis endotoxin on in vitro rat neutrophil cyclo-oxygenase and lipoxygenase metabolism, phagocytic activity, superoxide (o2-) generation, and microbicidal activity was investigated. incubation of polymorphonuclear leukocytes (pmn) with 5, 25, and 50 micrograms of endotoxin significantly enhanced synthesis of immunoreactive (i) leukotriene (lt)c4/d4 and thromboxane (tx)b2 (p less than 0.001) as compared to control cells. endotoxin 5 micrograms/ml produced optimal st ...19882832910
[aph(3')-ii phosphotransferase determination using protein transfer (western blotting)].the aph(3')-ii aminoglycoside-phosphotransferase has been studied by protein blotting. this technique allowed the detection of the enzyme in the crude extracts from clinical isolates of enterobacteriaceae, and the molecular weight determination of the aph(3')-ii. the obtained molecular weight of 25,000 is coincident with the previously reported value determined by a different method. these results demonstrate that this technique is useful for the study of aminoglycoside-modifying enzymes.19872855905

effect of repetitive low-dose endotoxin on liver parenchymal and kupffer cell fibronectin release.repetitive low-dose endotoxin, at a dose which will result in endotoxin tolerance, produces a marked but transient 2- to 3-day increase in plasma fibronectin. this elevation of fibronectin appears to contribute to increased hepatic kupffer cell phagocytic function observed with repetitive low-dose endotoxin administration. although numerous cell types synthesize fibronectin, hepatocytes are believed to be the major cell source of fibronectin in the plasma. since kupffer cells also synthesize fib ...19892925162
differential regulation of effector responses of cell mediated immunity in experimental salmonellosis.delayed type hypersensitivity (dth) and protective cell mediated immunity showed different profiles with respect to time following intraperitoneal immunization with live salmonella enteritidis. whereas the dth response decreased with time the protection index increased. the decline in dth response was found to be associated with suppressor cells generated by intraperitoneal immunization and could be prevented by cyclophosphamide treatment prior to immunization. it was concluded that the two effe ...19862938854

protective effect of a selective leukotriene antagonist in endotoxemia in the rat.the role of lipoxygenase metabolites as inflammatory mediators in endotoxic shock remains uncertain. in the present study, the effects of a selective leukotriene (lt) d4/lte4 antagonist, ly171883, 1-[2-hydroxy-3-propyl-4-[4-(1h-tetrazol-5-yl)-butoxy]-phenyl ethanone], on endotoxin-induced sequelae in the rat were assessed. ly171883 was given as a bolus (30 mg/kg i.v.) 10 min before salmonella enteritidis endotoxin (40 mg/kg) in ketamine-anesthetized (200 mg/kg i.m.) rats, followed by an infusion ...19852997435
cloned, random chromosomal sequences as probes to identify salmonella species.we have developed and evaluated a new technique--chromosomal probe fingerprinting--to differentiate between strains of salmonella species by using sequences of cloned chromosomal dna as probes to highlight restriction site heterogeneity. chromosomal probe fingerprint patterns were compared with other strain-typing methods and epidemiological data. seventeen isolates of salmonella typhimurium recovered from 11 outbreaks had six unique chromosomal probe fingerprint patterns. most strains of salmon ...19863011919
characteristics of myocardial beta-adrenergic receptors during endotoxicosis in the rat.the effects of in vivo endotoxin administration on beta-adrenergic receptors in rat ventricle membranes were studied using [3h]dihydroalprenolol as a radioligand. nonlinear regression analysis of saturation binding indicated one-site binding of antagonist in both control and endotoxic tissues. there was no change in maximum binding or dissociation constant of [3h]dihydroalprenolol at 0.5 or 3 h after endotoxin administration or when the rats were in the agonal stage of shock. isoproterenol compe ...19863017135
polymyxin-b inhibition of lps-induced interleukin-1 secretion by human monocytes is dependent upon the lps origin.polymyxin-b (pmb) is an antibiotic known to inhibit various biological activities induced by lipopolysaccharides (lps). we have investigated the ability of pmb to inhibit lps-induced interleukin-1 (il-1) secretion by human monocytes in vitro. interleukin-1 was assayed by the conventional comitogenic assay using mice thymocytes. our data demonstrate that pmb (1-2 micrograms/assay)-mediated inhibition of lps-induced il-1 secretion depends on the origin of the lps. interleukin-1 secretions induced ...19863023974
beneficial effects of a leukotriene antagonist on endotoxin-induced acute hemodynamic alterations.the role of lipoxygenase metabolites of arachidonic acid as inflammatory mediators of endotoxin shock remains uncertain. in this study the effect of ly171883, a selective leukotriene d4/e4 antagonist, on the hemodynamic alterations of endotoxin shock was assessed. adult male rats were given an intraperitoneal injection of ly171883 (30 mg/kg) or vehicle 10 minutes prior to intravenous injection of endotoxin (15 mg/kg) or vehicle. cardiac output, mean arterial pressure, and multiple organ blood fl ...19873038364

[interference of the intestinal ecosystem of mice in the oral administration of lyophilized live bacteria].oral vaccines mode by living or killed bacteria are commonly used to restore normal intestinal flora; it's not well know, however, which bacteria play the leading part in this ecosystem. in the present paper authors have intended to compare the effectiveness of an oral vaccine, made by bifidobacterium bifidus and lactobacillus acidofilus, with another of similar use, made by enterococci, to increase the mouse resistance to lethal salmonella enteritidis infections. according to collected microbio ...19863119409
modulation of arachidonic acid metabolism in experimental arthritis induced by salmonella enteritidis. i. effect of ibuprofen and flurbiprofen on experimental arthritis induced by salmonella enteritidis.oral administration of two nonsteroidal anti-inflammatory drugs, ibuprofen and flurbiprofen, can suppress the salmonella-induced arthritis in rats. the joint swelling index of arthritic paws showed suppression of arthritis in animals treated with the drugs, this effect being greater with flurbiprofen. measurement of 5 eicosanoids in femoral vein plasma showed increase of arachidonic acid products in salmonella-treated rats. inhibition of joint inflammation resulting from treatment with ibuprofen ...19873124133
survival of pathogenic bacteria in environmental microcosms.the survival times of salmonella enteritidis, pseudomonas aeruginosa, staphylococcus aureus, and vibrio cholerae in natural soil and river water samples were monitored by using various differential media. s. aureus and v. cholerae failed to survive in samples of soil, groundwater, and river water with various degrees of eutrophication. the population of the introduced s. enteritidis remained fairly constant in all three samples of soils tested. in water samples, numbers of s. enteritidis and p. ...19873130237
[the use of uv rays for the disinfection of water. i. microbiologic studies of drinking water].as a physical disinfection method without chemicals required the ultraviolet irradiation was tested for disinfection of drinking water. the survival was measured as a function of exposure to radiation for s. enteritidis, e. cloacae, c. freundii, s. marcescens, e. coli, k. pneumoniae und s. faecium. the bacteria were grown in trypton soya broth until they were well into the exponential phase. two different uv-disinfection units were tested. both consist of cylindrical shaped chambers with one low ...19883131986

effect of lipopolysaccharide on proteoglycan synthesis by adult human gingival fibroblasts in vitro.the effect of lipopolysaccharide preparations from salmonella enteritidis, bacteroides gingivalis, and actinobacillus actinomycetemcomitans on human gingival fibroblasts was studied. lipopolysaccharide from all sources inhibited fibroblast proliferation in the concentration range of 0.5 to 50 micrograms/ml, with the lipopolysaccharide from a. actinomycetemcomitans having the strongest inhibitory effect. assessment of the effect of lipopolysaccharide on gingival fibroblast metabolism indicated bo ...19883165085
beneficial effects of a 5-lipoxygenase inhibitor in endotoxic shock in the rat.the effects of a highly selective 5-lipoxygenase inhibitor, cgs8515 [methyl 2-[(3,4-dihydro-3,4-dioxo-1-naphthalenyl) amino]benzoate], on endotoxic shock sequelae and eicosanoid synthesis by peritoneal macrophages were evaluated in the rat. pretreatment of peritoneal macrophages in vitro with cgs8515 significantly inhibited the synthesis (p less than .01) of immunoreactive leukotriene c4/leukotriene d4 stimulated by the calcium ionophore (a23187). inhibition of 5-lipoxygenase produced significan ...19883171981
quantitative analysis and partial characterization of cytotoxin production by salmonella strains.the pathogenesis of the wide-spectrum human disease caused by salmonella species is poorly understood. cytotoxin production by other enteric pathogens has been increasingly investigated recently, and data are accumulating regarding the role of cytotoxins in enteric infections and hemolytic uremic syndrome. we studied the cytotoxic activity of 131 salmonella strains of the major serotypes, including 94 strains of salmonella enteritidis, 12 strains of salmonella typhi, and 25 strains of salmonella ...19883182072
cardiac function and coronary flow in chronic endotoxemic pigs.we have reported that myocardial inotropism was depressed in acute and chronic endotoxemia. one possible mechanism for this observation is that endotoxemia reduces myocardial perfusion and indeed, we observed reduced myocardial perfusion in acute endotoxemia. this study tested the hypothesis that reduced inotropism of chronic endotoxemia was accompanied by reduced coronary artery blood flow. fifteen pigs were equipped with left atrial and ventricular catheters, circumflex coronary and pulmonary ...19883194439
survival and virulence of salmonellae in water.survival and virulence of salmonellae in drinking and surface waters were tested in a series of model experiments using suspensions of fresh strains of salmonella enteritidis as a tester strain. environmental conditions in surface water, modeled by the addition of increasing amounts of municipal sewage, were simulated to have the organic pollution load equivalent cod to 5.3-9.7-15.2 mg o2/l and the coliform counts ranging from 2 x 10 to 2 x 10(3) per ml water. the experiments were carried out at ...19883198915
[the aerobic intestinal flora of the microchiropteran bat chaerephon pumila in madagascar].from stools of 88 malagasy insect eater bats chaerephon pumila, a large amount of bacterial strains were isolated. twenty different species were recognized, most of them belonged to enterobacteriaceae family. eight strains were identified as salmonella enterica subsp. enterica o48: -; 1.5, despite many atypical characters. strains of salmonella enteritidis, koserella trabulsii, kluyvera sp., odc negative serratia marcescens, atypical hafnia alvei... were also identified.19883240566
