res uptake of red blood cell stroma: time course of effects on phagocytic function and susceptibility to endotoxin shock. | previous studies have demonstrated that the injection of red blood cell (rbc) stroma to simulate the reticuloendothelial system (res) uptake of rbc debris following intravascular hemolysis causes an acute depression in res phagocytic function and an increase in shock susceptibility. the present study evaluated the time course of these changes. initial studies demonstrated that the uptake of iodinated rbc stroma was followed by a decrease in the amount of radioactivity present in the liver betwee ... | 1983 | 6362903 |

[erythrocyte antigen for the rapid intravital diagnosis of fowl typhoid and pullorum disease]. | a stable erythrocyte antigen was obtained for the rapid diagnosis of typhoid and pullorum disease in birds, which was tested under laboratory and field conditions. it was found that with the use of whole blood or serum taken from birds that had been either experimentally infected or had died of spontaneous infection of salmonella gallinarum and salmonella enteritidis the erythrocyte antigen was substantially superior to the routinely used colour ordinary test-antigen in terms of time consumed, i ... | 1983 | 6364560 |
suppression of fever after lesions of the anteroventral third ventricle in guinea pigs. | endogenous pyrogen (ep), injected systemically or intracerebrally, evokes fever and certain changes in plasma trace metal and glycoprotein levels which are characteristic of the acute-phase reaction. it is generally assumed that ep enters the brain from the blood, although it has not yet been demonstrated that ep crosses the blood-brain barrier (bbb). the possibility that ep might penetrate the brain through the organum vasculosum laminae terminalis (ovlt), which is outside of the bbb and locate ... | 1983 | 6365250 |
effect of surgical trauma on various aspects of the immune response in rats. | the effects of a standard laparotomy on different aspects of the immune response were studied in wistar r/a rats. when the antigen was administered at the time of operation, antibody synthesis against sheep red blood cells (srbc), a thymo-dependent antigen was significantly stimulated. the same phenomenon was observed when a soluble antigen extracted from srbc was injected during the surgical procedure. on the contrary, late antibody production induced by formalinized salmonella enteritidis or e ... | 1984 | 6365568 |

suppurative epididymo-orchitis due to salmonella enteritidis. | a 50-year-old man developed suppurative epididymo-orchitis 3 weeks after an episode of gastroenteritis. culture of the removed testis yielded salmonella enteritidis. the importance of remembering salmonella in the differential diagnosis of epididymo-orchitis is stressed. | 1984 | 6366070 |
[fermentation and colicinogeny for differentiation of salmonella enteritidis (gaertner's bacterium)]. | study material of 435 strains of salmonella enteritidis which were predominantly cultivated from human specimens in schleswig-holstein in the years from 1968 to 1978, was used for investigating the biochemical differentiation by the fermentation of arabinose, dulcitol, rhamnose and glycerol (method after kauffmann); moreover, the decarboxylation of lysine and the gas formation from glucose as well as the colicinogenicity (indicator escherichia coli k 12 row) were tested. the 4 classical biotypes ... | 1983 | 6367305 |

the bactericidal and opsonic effects of serum from patients with sickle cell anaemia. | the bactericidal and opsonic activity of serum from 12 homozygous sicklers was compared with that of a single control pool of healthy nonsickler african serum. factorially designed experiments were used to calculate 4 indices which were expressed as the ratio of test to control. using s. enteritidis and normal human neutrophils viability indices (vi) were calculated for serum, for ingested organisms and for cells + serum, together with a phagocytic index (pi) for cells. only 1 of the 12 sickler ... | 1983 | 6370481 |
bacteremia in hospitalized black south african children. a one-year study emphasizing nosocomial bacteremia and bacteremia in severely malnourished children. | during a one-year period, 315 of 5,397 children admitted to the general pediatric wards of a hospital had bacteremia. the commonest causative organisms were streptococcus pneumoniae, salmonella enteritidis, hemophilus influenzae, and escherichia coli. most episodes of bacteremia were associated with gastroenteritis, pneumonia, or meningitis. seventy-eight episodes occurred in children with severe protein-energy malnutrition, and 46 episodes were hospital acquired. the overall case fatality rate ... | 1984 | 6372439 |
loss of hepatic venous responsiveness after endotoxin in anesthetized cats. | endotoxin (from salmonella enteriditis ) was administered either as an intravenous bolus injection after administration of indomethacin to prevent the acute anaphylactoid response or as a slow intravenous infusion to cats anesthetized with pentobarbital. within 30 min, hepatic blood volume measured by plethysmography increased by 30%. however, unlike the outflow block seen in dogs after endotoxin, this increase in blood volume was associated with a fall in portal and hepatic lobar venous pressur ... | 1984 | 6372524 |
bactericidal activities of chloramphenicol and eleven other antibiotics against salmonella spp. | the bactericidal activity of chloramphenicol against 27 strains of salmonella typhi and 33 strains of s. enteritidis was compared with those of 11 other antibiotics. the geometric mean bactericidal concentrations of chloramphenicol against susceptible strains (36.10 and 43.13 micrograms/ml for s. typhi and s. enteritidis, respectively) far exceeded those of the other 11 antibiotics, with cephalothin having the next highest values (2.67 and 8.66 micrograms/ml) and moxalactam (0.09 and 0.28 microg ... | 1984 | 6372681 |
viable but nonrecoverable stage of salmonella enteritidis in aquatic systems. | an environmental isolate (13- 1bb ) of salmonella enteritidis serogroup c1 was inoculated into sterile potomac river water microcosms to observe survival and culturability of the organism by employing acridine orange direct count, fluorescent antibody direct count, direct viable count, plate count on veal infusion agar and xylose lysine decarboxylase agar, and indirect enumeration by the most-probable-number method (mpn), using media selective for salmonella. loss of culturability on laboratory ... | 1984 | 6372975 |
