| [enteric infections by salmonella: occurrence of positive blood cultures, positive urine cultures and high antibody titres (author's transl)]. | in the last two decades the classic typhoid and paratyphoid a and b became rare also in istria being substituted by infections of salmonellas of the "minor group". basing on observations on 418 patients (1970-1979) it was established that in 48.5% of them a significant increase of titers of antibodies, not only for group antigens but also for phasis antigens developed. this, together with positive hemocultures and urine cultures in a number of them, did lead the authors to the conclusion that th ... | 1981 | 7023127 |
| [active immunization to experimental salmonellosis in mice protective properties of salmonella r mutants against infection with different pathogenic salmonella species (author's transl)]. | mice (nmri) were immunized twice with acetone-killed bacteria from 13 different salmonella r-mutant and 6 salmonella s form strains. of the r mutants one strain was a semirough mutant, 9 strains belonged to the chemotype ra, one to chemotype rb2 and 2 to chemotype re. of the s forms 2 strains derived from serological group b, 2 from group d1 and one strain from each of group c1 and c2. ten days after immunization the animals were challenged with increasing numbers of s-form bacteria (the same s ... | 1981 | 7023133 |
| reticuloendothelial system depression with hemolyzed blood and susceptibility to endotoxin shock and thermal injury. | the present study was carried out to determine if the reticuloendothelial system (res) depression induced by the injection of hemolyzed blood and components of hemolyzed blood was associated with an increase in susceptibility to endotoxin shock and thermal injury. hemolyzed blood and the particulate stroma fraction, but not the soluble supernatant fraction of hemolyzed blood, depressed res phagocytic function at a dose of 0.3 ml/100g in rats. hemolyzed washed red blood cells (rbc) and hemolyzed ... | 1981 | 7023739 |

| effector cell-mediated immune response in mice immunised with salmonella. | effector responses of cell-mediated immunity were studied in mice immediately and 3 months after immunisation with different kinds of salmonella vaccine. whereas immunisation with live salmonella enteritidis generated delayed hypersensitivity and activated macrophages, immunisation with formalised vaccine generated neither. although activated macrophages had declined considerably by 3 months after immunisation, the delayed-hypersensitivity response had persisted. it was possible to generate acti ... | 1982 | 7143429 |
| effects of salmonella infection on hemopoietic stem cells in mice. | effects of induced salmonella infection on hemopoietic stem cells were studied by comparing hemopoietic response of mice to killed and viable bacteria of an attenuated strain of salmonella enteritidis. results are as follows: i) a single injection with viable bacteria induced an increase in pluripotent stem cells (cfuc) and granulocyte-macrophage progenitor cells (cfus) in the spleen and a decrease in these cells in the bone marrow, ii) a single injection or repeated injections of killed bacteri ... | 1982 | 7182012 |
| effects of salmonella infection on hemopoietic stem cells in mice immunized with salmonella vaccines. | effects of salmonella enteritidis infection on hemopoietic stem cells were examined in mice immunized with killed bacteria and in those immunized with viable bacteria. the results are summarized as follows: i) mice immunized with the killed salmonellae showed hemopoietic responses similar to those of normal, nonimmunized mice, i. e., increase in cfus and cfuc in the spleen and decrease in these cells in the bone marrow. ii) mice immunized with viable salmonellae were protected from such decrease ... | 1982 | 7183342 |
| relationship between tumour resistance and the in vitro and in vivo cytotoxicity elicited by salmonella antigens in immunized mice. | immunization of mice with the attenuated 11rx strain of salmonella enteritidis (11rx) induces resistance to intraperitoneal (i.p.) tumour growth. tumour resistance is much greater and lasts for a longer time following i.p. immunization than following intravenous (i.v.) immunization. this paper extends our previous observations that, after this resistance is lost, it can be recalled by a t cell-mediated reaction to an antigenic extract of the bacteria (11rx antigen) which is not protective in uni ... | 1982 | 6763525 |

| beneficial effects of uk 37248, a thromboxane synthetase inhibitor, in experimental endotoxic shock in the rat. | 1 the effects of pretreatment with the thromboxane synthetase inhibitor uk 37248 (dazoxiben) administered 30 min before intravenous endotoxin (s. enteriditis) in the rat was investigated 2 plasma prostaglandins and thromboxanes were determined via radioimmunoassay. endotoxaemia was associated with significant elevations above control values (less than 200 pg/ml) in plasma thromboxane b2 (txb2), prostaglandin e (pge) and 6-keto-prostaglandin f1 alpha (6-keto-pgf1 alpha). within 30 min after endot ... | 1983 | 6337604 |
| rapid method for detection, identification, and susceptibility testing of enteric pathogens. | three hundred and seven colonies believed to be enteric pathogens were selected from primary plates of macconkey, xylose desoxycholate, or salmonella-shigella agar for inoculation to lactose-sucrose broth, urea-41 motility medium, modified andrade glucose broth with inverted durham tube, pregrowth broth, triple sugar iron agar, lysine iron agar (lia), and christensen urea agar. the rapid screen consisted of interpreting the lactose-sucrose, urea-41 motility, and modified andrade glucose broth ga ... | 1983 | 6338037 |
| role of the liver in endotoxin-induced hyperinsulinemia and hyperglucagonemia in rats. | the intravenous administration of bacterial endotoxin to fasted rats elicited basal portal and systemic venous hyperinsulinemia and hyperglucagonemia. enhanced pancreatic secretion of insulin and glucagon was implied by the elevated portal venous hormonal levels. elevated insulin and glucagon levels were present at 4 hr after a 33 micrograms/100 gm intravenous endotoxin dose despite no fluctuation of the plasma glucose concentration. the role of the liver in the pancreatic hormonal response to e ... | 1983 | 6339352 |

| distinctive biochemical features of salmonella dublin isolated in california. | we examined 34 strains of salmonella dublin that were isolated in california between 1978 and 1982. all were of a characteristic biotype; they did not grow on simmons citrate or acetate and did not ferment arabinose. their apparent inability to use citrate as the only carbon source was due to a nutritional requirement for nicotinic acid. because s. dublin strains are of a characteristic biotype, are host adapted to bovines, and are unusually virulent for humans, we suggest that s. dublin be cons ... | 1983 | 6341406 |

| complement activation by polysaccharide of lipopolysaccharide: an important virulence determinant of salmonellae. | salmonellae with differences only in the o-antigenic polysaccharide of their lipopolysaccharide were previously shown to differentially activate complement via the alternative pathway, causing them to be ingested at different rates by the mouse macrophage-like cell line j774. we now show that this mechanism could explain the different virulence of these strains in vivo. mouse peritoneal macrophages (thioglycolate induced) ingest these salmonellae at rates that are inversely proportional to the k ... | 1983 | 6347890 |
| cardiac and splenic norepinephrine turnovers in endotoxic rats. | although sympathetic hyperactivity has been implicated in the pathogenesis of endotoxin shock, methodologies employed to assess the activity have been indirect in nature and results have been equivocal. the present experiments quantitated postganglionic sympathetic activity by measuring norepinephrine (ne) turnovers in hearts and spleens of fasted male holtzman rats injected intravenously with salmonella enteritidis lipopolysaccharide (2 mg/300 g rat; 5.7-6.7 mg/kg). ne turnovers were measured o ... | 1983 | 6349387 |
| isolation of salmonella enteritidis, serotype horsham, from three american indian tribes. | salmonella enteritidis, serotype horsham, identified rarely worldwide, was isolated from the stools of six american indians with gastroenteritis. the patients were from separate tribes located in three geographically distinct villages. although significant contact was demonstrated between ill individuals within two tribes, no common source for the organism has been identified. | 1983 | 6350350 |

| non-typhoidal salmonella infection in zambian infants. | in the university teaching hospital, lusaka, zambia, 45 strains of various non-typhoidal salmonella species were isolated from 2990 samples of stools, blood and c.s.f. about 93% of the 45 strains were isolated from infants less than two years old. s. heidelberg was the most common species isolated from stools and revealed a multi-drug resistant character. only s. typhimurium and s. bovis-morbificans were isolated from blood and c.s.f. | 1983 | 6353686 |
| relation of endotoxin structure to hypoglycemic and insulinlike actions. | various endotoxin preparations were used to determine which portion of endotoxin, lipid a, polysaccharide, or lipid-associated protein (lap), mediates the hypoglycemic and insulinlike action in rats. salmonella enteriditis boivin (seb), complete endotoxin, and s enteriditis westphal (sew), lacking lap, were equally lethal to endotoxin-sensitized rats; however, s minnesota (sm) glycolipid (lipid a plus 16% polysaccharide) was comparatively more toxic. toxic effects were prevented by alteration of ... | 1983 | 6357529 |
| the transient appearance of igm antibodies in the bile of rats injected with salmonella enteritidis. | following the intravenous injection of 2 x 10(8) killed salmonella enteritidis into rats, high levels of specific antibodies were detected in the serum and bile after 4 days. the level in serum persisted while that in bile had virtually disappeared by day 7. on the basis of gel filtration on ultrogel aca22 the activity in bile was found to be associated with the igm fraction. the transient nature of the biliary response was further evidenced by the association of the agglutinating activity with ... | 1983 | 6358007 |
| effect of ibuprofen on fever and metabolic changes induced by continuous infusion of leukocytic pyrogen (interleukin 1) or endotoxin. | many of the metabolic sequelae to infection and inflammation, such as fever, trace mineral redistribution, skeletal muscle catabolism, and the acute-phase protein response, are mediated by leukocytic pyrogen (interleukin 1). in the anterior hypothalamus and in skeletal muscles leukocytic pyrogen appears to induce the synthesis of prostaglandin e2 which mediates fever and skeletal protein catabolism. it is unclear whether any additional metabolic responses to leukocytic pyrogen result from prosta ... | 1983 | 6358043 |
