| interferon and cytotoxic factor (cytotoxin) released in the blood of mice infected with mycobacterium bovis bcg. i. enhanced production of interferon and appearance of cytotoxin stimulated by capsular polysaccharide of klebsiella pneumoniae or bacterial lipopolysaccharide. | interferon production stimulated by the active substance (neutral fraction) of the capsular polysaccharide of klebsiella pneumoniae (neutral cps-k) in bcg-infected mice was compared with that by bacterial lipopolysaccharide (lps). prior infection with bcg increased the responsiveness of mice to the lethal effect of neutral cps-k as well as to that of lps. associated with this, bcg-infected mice showed a markedly enhanced ability to produce interferon after stimulation not only by lps but also by ... | 1979 | 41163 |
| delayed-type hypersensitivity and acquired cellular resistance in mice immunized with killed listeria monocytogenes and adjuvants. | delayed-type hypersensitivity (dh) and acquired cellular resistance (arc) to listeria monocytogenes in mice was studied following immunization with killed bacteria in combination with freund's complete adjuvant or the adjuvant dimethyldioctadecylammonium bromide (dda). intracutaneous or intraperitoneal injections of killed listeria mixed with freund's complete adjuvant did neither result in dh nor in acr. intracutaneous injections of killed listeria and dda resulted in an antigen-dose dependent ... | 1979 | 112043 |
| suppressive effect of bacterial endotoxin on the expression of cell-mediated anti-listeria immunity. | intravenous injection of bacterial endotoxin into mice at any time during ongoing infection with listeria monocytogenes resulted in a markedly increased multiplication of this organism in the liver and spleen. experiments designed to investigate the basis of this infection-enhancing effect revealed that endotoxin was also capable of inhibiting the expression of adoptive t-cell-mediated anti-listeria immunity if given to normal recipient mice up to 48 h before they were infused with protective t- ... | 1979 | 112056 |

| protection of mice against babesia microti with cord factor, coam, zymosan, glucan, salmonella and listeria. | cord factor (trehalose 6-6' dimycolate). coam (chlorite-oxidized oxyamylose), zymosan, glucan, salmonella enteritidis 11rx and listeria monocytogenes were found to protect mice against subsequent infection with babesia microti, an intra-erythrocytic protozoan parasite. this protection was not observed after injection of staphylococcus epidermidis, a viridans group streptococcus, thioglycollate, or colloidal carbon. all the agents which protect against b. microti have also been reported to induce ... | 1979 | 121772 |
| resistance of essential fatty acid-deficient rats to endotoxic shock. | the role of lipids in the altered energy metabolism of shock remains to be delineated fully. during the course of our studies of endotoxic shock, the susceptibility of essential fatty acid (efa)-deficient rats to endotoxin was evaluated. intravenous administration of s. salmonella enteritidis endotoxin (1 mg/100 gm) in normal male long-evans rats (7--8 weeks old) produced severe shock with an 88% mortality. in marked contrast, injection of this dose of endotoxin in efa-deficient rats of the same ... | 1979 | 394879 |
| diagnosis of salmonella infections: specificity of indirect immunofluorescence for rapid identification of salmonella enteritidis and usefulness of enzyme-linked immunosorbent assay. | an indirect immunofluorescence (ifl) method was used for diagnosis of infections caused by salmonella enteritdis during an epidemic. antiserum prepared against the synthetic disaccharide tyvelose 1 leads to alpha 3 d-mannose, representative of salmonella o antigen 9, covalently linked to bovine serum albumin, was used. of 43 decal samples examined, 28 were positive for s. enteritidis by culture. ifl was applied (1) directly on fecal smears, (2) on enrichment broth cultures after incubation for 1 ... | 1979 | 396337 |
| shigella dysenteriae 1-like cytotoxic enterotoxins produced by salmonella strains. | a salmonella enteritidis strain produced a cytotoxin in addition to heat-labile (lt) and heat-stable (st) enterotoxins. two strains of serotypes salmonella kapemba and salmonella thompson were lt and st negative, but exhibited a cytotoxic effect. after sephadex g-100 fractionation of the crude s. enteritidis material, some high and low molecular fractions had both cytotonic and cytotoxic activities. of the two other salmonellae, only some high molecular fractions contained the cytotoxic substanc ... | 1979 | 396765 |
| cross-protection aginst salmonella enteritidis infection in mice. i. immunization trials. | mice were immunized subcutaneously with live and killed vaccines, with and without complete adjuvant incorporating salmonella typhi-murium m206, salmonella gallinarum 9r, salmonella pullorum sp223 as well as homologous salmonella enteritidis se795. the animals were challenged 21 days post-vaccination with 100 ld50 of virulent s. enteritidis 5694 smr subcutaneously along with unvaccinated control mice. to assess the immunity against acute and chronic infections, the percentage of absolute survivo ... | 1979 | 397731 |
| cross-protection against salmonella enteritidis infection in mice. | mice were immunized subcutaneously with live vaccines and live vaccines with complete adjuvant incorporating salmonella enteritidis se 795, salmonella typhi-murium m206, salmonella gallinarum 9r or salmonella pullorum sp223. they were challenged along with unvaccinated controls with 100 ld50 of virulent s. enteritidis 5694 smr subcutaneously on the 21st day post-vaccination. the humoral immune response was studied by assessing the sequential level of agglutinins, complete and incomplete somatic ... | 1979 | 397732 |
| cross-protection against salmonella enteritidis infection in mice. iii. delayed hypersensitivity reaction and clearance of the challenge organism. | mice were immunized with live vaccines and with live vaccines with complete adjuvant incorporating salmonella enteritidis, salmonella typhi-murium, salmonella gallinarum or salmonella pullorum. on the 21st day after vacination, the hypersensitivity reactions elicited by the mice to extracts of the challenge organism (s. enteritidis 5694 smr) were assessed. the degree of delayed hypersensitivity reaction was compared with the level of protection induced by the vaccine. the role in protection of d ... | 1979 | 397733 |
| a supplemental test system to measure competitive exclusion of salmonellae by native microflora in the chicken gut. | an improved individual challenge test system is described for evaluation of competititve exclusion of salmonellae in day-old chicks by native gut microflora. evaluation of salmonella protection is based on culture of cloacal and fecal samples by enrichment methods plus enumeration of salmonellae in fresh droppings collected from test groups. the use of a nalidixic-acid-resistant strain of salmonella allowed for ease of measurement. comparative data are included that were developed by parallel te ... | 1979 | 397829 |
| inhibition of the growth of lewis lung carcinoma in syngeneic mice by salmonella antigens. | administration of a protein antigen preparation from salmonella enteritidis 11rx at the site of challenge with lewis lung carcinoma inhibited tumour development in mice previously immunised with live bacteria, but not control mice. the kinetics of tumour growth indicated that the inhibition of tumour development was due to a reduction of the initial tumour inoculum rather than the development of specific anti-tumour immunity. | 1979 | 398698 |
| the intestinal flora and infant botulism. | the intestinal flora of experimental animals interferes with infection by species of salmonella and shigella. protection against infection with these organisms appears to be related to high concentrations of volatile acids, low ph, and low oxidation-reduction potential of the intestinal contents of animals with an intact flora. there are no data to show that the flora influences colonization of the intestine with clostridial species, but indirect evidence suggests that the intestinal flora may b ... | 1979 | 399374 |

| carbohydrate metabolism in c3h/hej (nonresponder) mice during endotoxic shock. | this study was undertaken to evaluate the hypoglycemic effects of endotoxin in c3h/hej (nonresponder) mice. endotoxin from salmonella enteritidis ser typhimurium strain sr-11 was used and the median lethal dosed (ld50) for random-outbred swiss-webster mice and c3h/hej mice were 450 microgram and 3,000 microgram, respectively. at intervals after intraperitoneal injection of endotoxin (1 ld50) animals were killed, and blood glucose, liver glucose, and liver glycogen levels were killed, and blood g ... | 1979 | 400573 |
| [salmonella-cholecystitis (author's transl)]. | gastroenteritis due to salmonella enteritis is an endemic disease in our region, extraintestinal manifestations however are rare. we report a 8 years old girl who presented after 4 days of an unspecific diarrheal disease with watery liquid stools, vomiting, abdominal cramps, fever above 39 grad c and symptoms and signs of an acute abdominal emergency. mid abdominal laparotomy disclosed a cholecystitis with reactive peritonitis. cultures of bile showed salmonella group b as the causative organism ... | 1979 | 530733 |
| genetics of natural resistance to salmonellae in mice. | the genetics of natural resistance to salmonellae were studied in f1 hybrid and backcross mice. overall resistance to salmonella typhimurium c5 is complex, but one parameter, the early net growth rate of the organism in vivo, is controlled by a single autosomal gene or cluster of genes. 'slow' net growth rate is necessary but insufficient, for resistance to s. typhimurium c5. resistance requires the participation of other mechanisms, detectable by the end of the first week, which presumably invo ... | 1979 | 381179 |
| the removal of 14c labeled endotoxin by activated charcoal. | endotoxin shock due to gram-negative enteric bacteria is of major medical concern with an estimated 100,000 fatalities in the united states per year. an effective therapy for endotoxin shock, particularly in combination with significant liver damage, has not been available to date. since activated charcoal is known as a universal sorbent, the use of activated charcoal in a hemoperfusion apparatus to remove endotoxin has interesting possibilities. current assays for endotoxin are inadequate. the ... | 1979 | 381215 |
| transmissible antibiotic resistance in salmonella isolated from random-source cats purchased for use in research. | salmonella isolates from random-source cats designated for use in research were examined for antibiotic susceptibilities and the presence of plasmids containing r factors. the serotypes studied were salmonella derby, s typhimurium, s anatum, s enteritidis, and s bredeney. eighty percent of the isolates were resistant to one or more antibiotics. the greatest frequency of resistance was to streptomycin. the majority of the salmonella isolates transferred all or a part of their antibiotic resistanc ... | 1979 | 382928 |
| fever and survival in the rat. the effect of enhancing fever. | to study the effect of fever on infectious disease in a mammal, rats, partially restrained by an antirotatory device and with chronically implanted preoptic thermodes, were injected with salmonella enteritidis and, in some of them, the hypothalamus was then continuously cooled to enhance the febrile response. all animals developed a fever that peaked 2 days after the infection, reaching 40.9 +/- 0.2 (sd) degrees c in the nine hypothalamic cooled and only 39.8 +/- 0.4 degrees c in the 13 control ... | 1979 | 384358 |

| complement-independence of the acute-phase production of serum amyloijd p-component (sap) in mice. | mice depleted of circulating c3 by injection of cobra factor (cof), the c3-activating protein of cobra (naja naja) venom, mounted the same acute-phase responses of serum amyloid p-component (sap) to subsequent injection of casein, bacterial lipopolysaccharide or croton oil as did normal control mice. there was also evidence for accelerated synthesis of c3 itself in response to injection of these acute-phase stimulants in cof-treated mice. on the other hand complement activation produced by injec ... | 1980 | 7000131 |
| factors affecting the ability of various strains of enterobacteriaceae to induce tumour resistance in mice. | primary infection of mice with salmonella enteritidis 11rx (11rx) confers resistance to challenge with 10(4) ld50 doses of ehrlich ascites tumour (eat). a lipopolysaccharide-free protein extract of 11rx is capable of eliciting delayed type hypersensitivity (dth) reactions in these mice and of "recalling" tumour resistance in long-term 11rx immunised mice, which no longer exhibit any resistance to tumour challenge. in the present study, we have examined the ability of five other strains of entero ... | 1980 | 7002136 |
| cholera toxin-like toxin released by salmonella species in the presence of mitomycin c. | several serotypes of salmonella were shown to release increased amounts of a cholera toxin-like toxin during culture in vitro with mitomycin c (mtc). filter-sterilized culture supernatants containing the toxin caused elongation of chinese hamster ovary cells, which could be blocked by heating the supernatants at 100 degrees c for 15 min or by adding mixed gangliosides or monospecific cholera antitoxin. when mtc was not added to the salmonella cultures, little or no toxin was detected in crude, u ... | 1980 | 7002788 |
| mapping of genes determining penicillin-resistance and serum-sensitivity in salmonella enteritidis. | two presumptive single-step mutants, resistant to penicillin and sensitive to the bactericidal effect of normal human serum, were isolated on penicillin gradient plates from a smooth, penicillin-sensitive, serum-resistant strain of salmonella enteritidis (o9,12; gal hisei cys). the chemical composition of their lipopolysaccharides, their phage-sensitivity patterns, and their serological and cultural properties showed one to be 'part-rough' and the other smooth. hfr strains with o antigens o4,5,1 ... | 1980 | 7003058 |
