focal salmonella enteritidis infection of urinary tract.a case of upper urinary tract infection with salmonella enteritidis is presented. the patient was diabetic which may have resulted in diminished immunocompetence, but no other predisposing factor was uncovered. thorough search for an extraurinary primary source of this infection was unrevealing. the implications of this type of infection are reviewed.19873554703
thermoregulatory responses of guinea pigs with anteroventral third ventricle lesions.guinea pigs with anteroventral third ventricle region (av3v) lesions fail to develop fever and the associated rise in acute-phase plasma protein levels following systemic injections of lipopolysaccharide (lps). since endogenous pyrogen (ep) injected directly into the preoptic area of animals with av3v lesions causes appropriate elevations in core temperature (tco) and acute-phase plasma proteins levels, the blocked responses to lps probably are not due to damage to the adjacent preoptic area. we ...19873621074
acute diarrhoea in adults: a prospective study.a prospective study of 74 adults with acute diarrhoea was carried out in sydney in 1984-1985 to determine the infective agents that were involved and their relationship to clinical, epidemiological and laboratory features. thirty-four potential pathogens were identified in 32 (43.2%) patients. these included, in order of frequency: campylobacter spp., rotavirus, clostridium difficile, salmonella enteritidis, aeromonas hydrophila, vibrio parahaemolyticus, adenovirus, a small round virus and giard ...19873683260
alterations in cellular ca2+ regulation in the liver in endotoxic shock.effects of salmonella enteritidis endotoxin on cellular ca2+ regulation were studied in the liver. rats were given intravenous injections of saline (control) or endotoxin (15 mg/kg). they were killed 5 h later, at which time endotoxin-injected rats showed signs of shock. liver slices were used to measure ca2+ efflux from the intracellular ca2+ pool and the size of that pool. 45ca uptake was measured in isolated endoplasmic reticulum (er) from livers. 45ca efflux and uptake were also measured in ...19863706573
thermoregulatory and acute-phase responses to endotoxin of full- term-pregnant rabbits.fever, a fall in the plasma level of iron (fe), and rises in the levels of certain plasma glycoproteins (indexed by protein-bound-n-acetylneuraminic acid [nana]) normally occur during infection; they are thought to be mutually enhancing in host defense. it has been reported that fever is suppressed at full term of pregnancy; however, it is not known whether the blood chemical changes are similarly affected. also, the mechanism for the suppression of fever is controversial. since uteroplacental b ...19863710977
effect of endotoxic shock on kinetics of system a amino acid transport in rat soleus muscle.this study evaluated the kinetics of system a amino acid transport in soleus muscle during endotoxic shock. fasted male rats (80-100 g) were killed by decapitation 5 h after the intravenous injection of saline (control) or 20 mg/kg salmonella enteritidis endotoxin. soleus muscles (40 mg) from control or endotoxic rats were incubated in oxygenated krebs-ringer-bicarbonate buffer (ph 7.4) at 37 degrees c for 20, 40, or 60 min. initial rates of entry of alpha-aminoisobutyric acid (aib) into the inu ...19863728705
meningitis and septicaemia in adults splenectomized for hodgkin's disease.splenectomized and asplenic persons are at risk of developing sudden episodes of meningitis and/or septicaemia, frequently due to streptococcus pneumoniae (overwhelming postsplenectomy infection, or opsi). the application of staging splenectomy to patients with hodgkin's disease (hd) generated a new population at risk for opsi. we reviewed the cases of sudden meningitis and/or septicaemia in a series of 491 consecutive adults with hd. no case was recorded among 149 non-splenectomized patients. 6 ...19863738430
the relative role of paf-acether and icosanoids in septic shock.endotoxemia and gram negative sepsis remain a clinically important problem since mortality rate is still high in these diseases. recently, the participation of some new potential mediators in this pathology is beginning to be demonstrated but the results obtained on animal models with specific inhibitors are contradictory. in order to clarify the pathological importance of icosanoids and paf-acether in the septicemic process, we investigated the effects of indomethacin (ind) a cyclooxygenase inh ...19863774851
salmonellosis outbreak on transatlantic flights; foodborne illness on aircraft: 1947-1984.in march 1984, 186 cases of gastroenteritis due to salmonella enteritidis were reported after 29 flights to the united states on an international airline. an estimated 2,747 passengers on flights to the united states were affected. illness was associated with flying supersonic or first class (odds ratio = 15, p less than 0.001). eating food from the first-class menu was associated with illness (p = 0.09), and eating a tourist-class entree was protective (p less than 0.01). in 23 reported outbrea ...19873788944

restriction of gut-derived endotoxin impairs dna synthesis for liver regeneration.the influence of restricting gut-derived endotoxin availability on liver regeneration after partial hepatectomy was evaluated. partial hepatectomy was performed by 67% liver resection of ether-anesthetized rats. liver regeneration was quantified after partial hepatectomy by [3h]thymidine incorporation into hepatic dna; endotoxemia due to absorption of endogenous endotoxin from the gut into the portal circulation was determined by qualitative lysate assay of perchloric acid-extracted plasma sampl ...19853904484
salmonella bacteremia associated with the acquired immunodeficiency syndrome (aids).six cases of bacteremia due to serotypes of salmonella enteritidis are described in patients with the acquired immunodeficiency syndrome (aids). in four instances the bacteremia was recurrent despite appropriate antimicrobial treatment. neither a gastrointestinal tract source nor any other focus of infection could be identified in four of the six patients. in one patient an unusual salmonella infection, ie, pyelonephritis, was noted. the discovery of salmonella sepsis led in four cases to the in ...19853904653
increase in the susceptibility of salmonella strains to bactericidal activity of cord serum following treatment with agents disturbing surface structures.salmonella strains resistant to normal cord serum were found to become susceptible to it when the outer membrane was damaged by colistin, adult normal serum or tris-hcl buffer. the present results indicate that after such treatment cord sera exert bactericidal effect, despite significant deficiencies in factors playing an essential role in this process.19853904666
endogenous gut-derived bacterial endotoxin tonically primes pancreatic secretion of insulin in normal rats.this laboratory has proposed that endogenous gut-derived bacterial endotoxin primes the pancreatic secretion of insulin in normal rats. endogenous lipopolysaccharide (lps) is continually absorbed from the gut into intestinal capillaries, and low-grade portal venous endotoxemia is the status quo. under physiologic conditions, kupffer cells of the liver totally phagocytize and degrade endotoxin from the portal circulation. evidence from this and other laboratories indicates that administration of ...19853905458

spectrofluorometric and microfluorometric quantitation of antibacterial antibodies, using indirect immune fluorescence. preliminary report.the igg-fraction of rabbit hyperimune serum raised towards smooth salmonella typhimurium 395 ms (parent strain) and rough 395 mr10 (rd-mutant) was used in indirect immunofluorescence with bacteria in suspension or adsorbed to glass microscope slides. in the first case, igg-mediated fluorescence was determined with a standard cuvette-type spectrofluorometer; in the second case, in epifluorescence mode with a microscope fluorometer. in both assays the igg solution could be diluted to about 0.1 mic ...19853914822
phage types and epidemiological significance of salmonella enteritidis strains in hungary between 1976 and 1983.in hungary, 14 819 human salmonella enteritidis strains were isolated between 1976 and 1983. phage type was determined of 10 132 human strains originating from 6852 foci, and of 711 strains isolated from animals and water in this period. the human strains were typable in 99.4% and they belonged into 21 phage types. five phage types (1, 4, 7, 16 and 17) were more frequent than 1%. phage type 7 predominated among the strains isolated between 1976 and 1980, including 65.6%-89.3% of the strains. the ...19853915176
reactive hyperemic responses of single arterioles are attenuated markedly after intestinal ischemia, endotoxemia and traumatic shock: possible role of endothelial cells.there is at present no agreement as to why several organs in the body are often compromised very early after either blood and fluid loss or sepsis. close inspection (utilizing electron microscopy) usually reveals that a great many of the endothelial cells (ec) are either destroyed, transformed, or have undergone morphological changes. since: the intimal lining of blood vessels, i.e., ec, may be important in mediating vasodilator substances and mechanisms; and early in shock and trauma, the perip ...19853915339
salmonella vertebral osteomyelitis and epidural abscess in a child with sickle cell anemia.a case of salmonella vertebral osteomyelitis with epidural abscess in a child with sickle cell anemia is presented. spinal osteomyelitis is a rare event in children. although osteomyelitis in sickle cell anemia may occur in any bone, it has most often been documented as beginning in the medullary cavity of the long and tubular bones. this is in contrast to the clinical presentation of osteomyelitis in the normal individual, who is likely to have infection beginning in and restricted to the metap ...19853916460
the bacteriolytic action of mt-141, a new cephamycin antibiotic, on gram-negative bacteria.mt-141, a new cephamycin (7 alpha-methoxy-cephalosporin) antibiotic with a d-cysteine moiety in its 7 beta-side chain, has binding affinities to penicillin-binding proteins of escherichia coli and an inhibitory action on their transpeptidase activity similar to those of other structurally related cephamycins. yet this antibiotic was found to exert an exceedingly strong and rapid lytic action on sensitive gram-negative bacteria such as e. coli, klebsiella pneumoniae, serratia marcescens and salmo ...19853920178

a role for the spleen in the appearance of igm in the bile of rats injected intravenously with horse erythrocytes.the i.v. injection of the particulate antigens horse red blood cells (hrbc) and salmonella enteritidis into rats results in the appearance of high levels of igm agglutinating antibody in the serum and bile. this is in contrast to the appearance of specific iga antibodies in bile after the injection of antigen into the peyer's patches. at the height of the response, a fivefold to 10-fold increase in total igm was found in bile, whereas there was no increase in iga or in total protein levels. the ...19853998463
the frequency of salmonellae on duck eggs.total plate counts on washed duck eggs from a breeder farm on long island were less than 30/shell during the winter (january to february) of 1982. clean unwashed eggs had counts less than 9 x 10(1)/shell, whereas dirty unwashed eggs had counts as high as 9 x 10(5)/shell. our results showed that washing with a chlorine sanitizer (under commercial conditions) was highly effective in reducing surface bacterial counts on egg shells. prolonged storage reduced bacterial counts on clean eggs, but it di ...19854001051
immunoglobulin m and immunoglobulin g responses in balb/c mice to conjugated outer membrane extracts of four salmonella serotypes.outer membranes (oms) of salmonella enteritidis, s. anatum, s. typhimurium, and s. infantis were extracted and cross-linked with glutaraldehyde to form a large macromolecular antigen. the antigen consisted of om proteins and lipopolysaccharide and was designated 4-omp-lps. polyacrylamide gel electrophoresis of extracted oms from each serotype revealed differences in protein profiles. s. enteritidis and s. infantis possessed a greater variety of proteins than did s. anatum and s. typhimurium. imm ...19854030094
increased myocardial contractility during endotoxin shock in dogs.the slope of the left ventricular (lv) end-systolic pressure-diameter relationship (ees) was analyzed in open-chest, pentobarbital-anesthetized dogs before and after endotoxin administration. a lead ii electrocardiogram, systemic arterial pressure, lv pressure, lv dp/dt, and lv minor axis diameter were measured. after control measurements were taken, dogs were given either 1 mg/kg salmonella enteritidis endotoxin (n = 5) or an equivalent volume of saline (n = 4). control dogs were followed for 2 ...19854051010
local transfer of delayed-type hypersensitivity after salmonella infection in mice.an adoptive local transfer system has been used to study the mediators of delayed-type hypersensitivity induced in mice by infection with salmonella enteritidis 11rx. the cells which transfer this state of hypersensitivity to untreated recipients are nonadherent t lymphocytes with the surface phenotype lyt 1+2-, and successful transfer requires compatibility at the i-a subregion of the h-2 complex. in these and other respects these cells are indistinguishable from those previously found to be re ...19854066031
bacterial isolates from nsukka meat market: a zoonotic appraisal.swabs collected from butchers hands, knives, tables and meat displayed for sale at nsukka meat market showed that every item screened was contaminated. bacteria isolated include streptococcus faecalis, coagulase positive staphylococcus, clostridium perfringens, brucella species, corynebacterium haemolyticum, proteus mirabilis, p. vulgaris, escherichia coli, salmonella enteritidis, enterobacter aerogenes, pseudomonas multophilia, p. rubescens and beta-haemolytic streptococci. the zoonotic or publ ...19854077409

experimental salmonellosis: hypersensitivity to cell wall lipopolysaccharide and anti-infectious resistance of mice infected with salmonella.mice infected with various strains of salmonella enteritidis and s. typhimurium were found to be more sensitive to the cell wall lipopolysaccharide (lps) extracted from certain strains of salmonella than noninfected mice. this hypersensitivity was induced by those smooth or rough strains which possessed a polysaccharide chain longer than that of a glucoseless mutant. the major antigenic group participating in this hypersensitivity was presumed to be in rough core polysaccharide sequence because ...19714117290

preparation, sensitivity, and specificity of limulus lysate for endotoxin assay.limulus amoebocyte lysate was prepared from a total of 180 crabs during 1971 and 1972 by using a slightly modified lysate preparation procedure. marked variability of lysate potency was noted both years. in addition, lysate quality appeared diminished in 1972 as compared with 1971. different lysate batches were evaluated for potency by using a variety of endotoxin preparations. variations in batch potencies were observed, but little variation in reactivity among different endotoxin preparations ...19734199336
