enhancing effect of salmonella enteritidis spa on nonspecific resistance.	the peritoneal macrophages from mice treated with soluble protective antigen (spa) or lipopolysaccharide (lps) showed an increase in chemotactic activity, but muramyl dipeptide (mdp)-induced macrophages did not show any enhancing effect. conversely, the chemotactic activity of mice peritoneal neutrophils was enhanced by spa, lps or mdp treatment. the superoxide anion (o2-)-generating activity of spa-induced macrophages was higher than lps or mdp. and even 30 days after spa treatment, a significa ...	1989	2550565
molecular cloning and analysis of the incompatibility and partition functions of the virulence plasmid of salmonella typhimurium.	the incompatibility functions (inc) of the virulence plasmid of salmonella typhimurium lt2 were initially located in a 4.3 kb region near the repa locus of the plasmid. expression of inc required the presence, in cis or in trans, of two distinct dna regions of the fragment. these regions, maximally 0.3 kb and 0.6 kb in size, were separated in the fragment by c. 3.0 kb. this intervening dna encoded two proteins, of mr values 37 kda and 40 kda. the promoter for the 37 kda protein lay in or near on ...	1989	2556621
dibutyryl-camp blocks endotoxin-induced lung injury in rats.	we investigated the effect of dibutyryl-camp pretreatment on endotoxin-induced hemodynamic changes and lung vascular injury in rats. in catheter-implanted, unanesthetized rats, intraperitoneal injection of salmonella enteritidis endotoxin (2 mg/kg) decreased cardiac output and systemic blood pressure while increasing total pulmonary vascular resistance. db-camp (1 mg given intraperitoneally every 30 min), although not significantly affecting cardiac output and systemic blood pressure, blocked th ...	1989	2557788
production of leukotriene b4 in parenchymal and sinusoidal cells of the liver in rats treated simultaneously with d-galactosamine and endotoxin.	a study was conducted to investigate production rate of leukotriene b4 (ltb4) in parenchymal and sinusoidal liver cells of rats with acute hepatic failure (ahf). ahf was induced by simultaneous administration of d-galactosamine (galn) and endotoxin (lps), and parenchymal as well as sinusoidal liver cells were isolated by collagenase perfusion method. following preincubation for 15 min, isolated cellular fractions were incubated with ca-ionophore (2 microm) for 5 min, and levels of ltb4 in cultur ...	1989	2558038
practical application of nucleic acid techniques to avian disease problems.	a workshop in which 17 practicing scientists participated was intended to address primarily people who use or could use biotechnology in their work and was confined to five techniques. endonuclease fingerprinting and mapping involved cleaving nucleic acid with a specific restriction enzyme and separating the nucleic acid fragments by electrophoresis. field and vaccine isolates of pasteurella multocida could be distinguished; salmonella enteritidis could be divided into three groups; chlamydia co ...	1989	2559697
specificity of salmonella porin as an eliciting antigen for cell-mediated immunity (cmi) reaction in murine salmonellosis.	the specificities of salmonella porin on elicitations of delayed-type hypersensitivity (dth) reaction and interleukin-2 (il-2) production in balb/c mice immunized with salmonella typhimurium were examined. only porin from s. typhimurium was capable of eliciting significant levels of dth and il-2 production in s. typhimurium-immunized mice, whereas no significant dth and il-2 production were induced by porin from salmonella enteritidis or escherichia coli. our observations suggested that salmonel ...	1989	2560131
concentration-dependent, stereoselective inhibition of the endotoxin-induced hemoconcentration in conscious rats with the peptidoleukotriene receptor antagonist sk & f 104353.	endotoxemia is associated with increases in a number of humoral mediators including vasopressin, thromboxane and leukotrienes (lt), all of which may participate in the pathophysiologic responses to endotoxemia. previous studies from our laboratory demonstrated that endotoxin-induced hemoconcentration was attenuated with a peptidoleukotriene receptor antagonist, sk & f 104353. the purpose of this study was to investigate further the mechanism of endotoxin-induced hemoconcentration. injection of l ...	1989	2560662
role of salmonella enteritidis lipopolysaccharide on anti-hsv activity of macrophages from different anatomical sites.	it is generally agreed that endotoxins from gram-negative bacteria play a modulatory role on several macrophage functions. the intrinsic activity versus herpes simplex virus type 1 and type 2 of kupffer cells, peritoneal and alveolar macrophages, harvested from normal and tumour-bearing rats, was evaluated. moreover, the effects of different intravenous treatments with s. enteritidis endotoxin were investigated. the antiviral activity of peritoneal, alveolar macrophages and kupffer cells from tu ...	1989	2561362

potent adjuvant action of lipopolysaccharides possessing the o-specific polysaccharide moieties consisting of mannans in antibody response against protein antigen.	it was previously reported that klebsiella o3 lipopolysaccharide (lps) exhibits extraordinarily strong adjuvant activity in augmenting antibody response against protein antigens in mice compared with other kinds of lps, for example, lps from escherichia coli o55, o111, and o127 and salmonella enteritidis. the present study was undertaken to clarify the relationship between the strong adjuvant activity in augmenting antibody response against deaggregated bovine gammaglobulin and the chemical stru ...	1985	2578897
protective effects of trans-13-apt, a thromboxane receptor antagonist, in endotoxemia.	the effect of the thromboxane a2/prostaglandin h2 (txa2/pgh2) receptor antagonist trans-7[2-(p-hydroxyphenethylamino)-cyclopentyl]-heptanoic acid (trans-13-apt) on certain pathogenic sequelae of endotoxic shock and associated changes in arachidonic acid metabolism in the rat was investigated. trans-13-apt, an analog of 13-azaprostanoic acid, was synthesized and found to block human platelet aggregation induced by the thromboxane mimetic u46619. pretreatment with trans-13-apt did not significantl ...	1985	2580129
a possible correlation between histological changes in regional subcutaneous tissue induced by bacterial lipopolysaccharides and their adjuvant activities.	previously it was demonstrated that klebsiella pneumoniae o3 lipopolysaccharide (ko3 lps) exhibited much stronger adjuvant action on antibody response to subcutaneously (s.c.) injected sheep red blood cells or deaggregated bovine serum albumin than did other kinds of lps, the r-form lps lacking the o-specific polysaccharide chain of ko3 lps (r-lps), and the lipid a fractionated from ko3 lps. we compared histological changes in the regional subcutaneous tissues of mice injected subcutaneously (s. ...	1989	2586346
high incidence of false positives by a latex agglutination test for the diagnosis of clostridium difficile associated colitis in compromised patients.	detection of clostridium difficile cytotoxin using cell culture assays for the diagnosis of antibiotic-associated colitis has been used for over a decade. because the methodology is time consuming and cumbersome, a recently introduced commercial latex agglutination (la) kit has attracted much attention. we compared the sensitivity and specificity of this method with the cytotoxic assay (cta) using diarrheal stools from 652 patients at a referral tertiary care center. specimens from 71 (10.9%) pa ...	1989	2591165

non-typhi salmonella bacteraemia.	we reviewed retrospectively the clinical records of patients with non-typhi salmonella bacteraemia in our hospital from 1979 to 1988. during the study period 45 non-typhi salmonella bacteraemias were diagnosed in 43 patients. ten patients were under one year old and 11 were over 60. seven cases of sepsis presented in patients with aids. only three episodes were nosocomially acquired. in two of three patients the bacteraemia was preceded by an episode of acute gastroenteritis and one third presen ...	1989	2689346
the adjuvant effect of a muramyl dipeptide (mdp) analog on temperature-sensitive salmonella mutant vaccine.	adjuvant effect of a synthetic muramyl dipeptide analog, mdp-lys (l18), murnac-l-ala-d-glu[lys(co-(ch2)16-ch3)-oh]nh2 on a live salmonella enteritidis vaccine, a temperature-sensitive mutant ts-o strain that was obtained from the virulent s. enteritidis no.11 strain and could not grow at 37 degrees c, but could multiply at 25 degrees c as fast as the parent strain, was examined. although the ts-o organisms were avirulent and could hardly multiply in vivo when the organisms were injected into c57 ...	1989	2689364
control, prevention and eradication of salmonella enteritidis infection in broiler and broiler breeder flocks.	salmonella enteritidis was identified by serological and bacteriological techniques in two clinically normal breeder flocks in an integrated broiler organisation in northern ireland. the organism was transmitted vertically to clinically affected progeny flocks. the infected breeder flocks were slaughtered and the infection throughout the organisation controlled and subsequently eradicated. a working group, consisting of the senior management of the broiler organisation and veterinary staff from ...	1989	2690452
serological and bacteriological investigations of chickens from flocks naturally infected with salmonella enteritidis.	groups of 10 birds were obtained from four flocks which had shown evidence of natural salmonella infection. s enteritidis had been isolated from three flocks and s typhimurium from the fourth. each bird was housed in a separate cage and blood samples and cloacal swabs were taken weekly to follow the course of natural infection. after four weeks the birds were killed and examined post mortem. the isolation of salmonella species could not be related to the serological results. in individual birds ...	1989	2690455
salmonella enteritidis phage type 4 from the contents of intact eggs: a study involving naturally infected hens.	two small flocks of egg-laying hens, naturally infected with salmonella enteritidis, were housed in individual cages so that their eggs could be identified. during a longitudinal study where the contents of 1,119 eggs were examined, 11 were positive for s. enteritidis. one isolate was phage type (pt) 33 the others were pt4. the production of infected eggs was clustered though intermittent. the positive eggs, which were produced by 10 of the 35 hens, were all found to contain fewer than 10 salmon ...	1989	2691262
a large outbreak of salmonella enteritidis phage type 4 associated with eggs from overseas.	in february 1989 the largest reported outbreak to date in the united kingdom of salmonella enteritidis phage type 4 (pt4) infection occurred following a wedding reception at a hotel. one hundred and seventy-three people met the case definition of illness of whom 118 had the organism isolated from their stools. a further 17 were found to be s. enteritidis pt4 positive, but were asymptomatic. lightly-cooked, egg-based sauces were the epidemiologically proven vehicles of infection. investigations s ...	1989	2691263

[epidemiology of salmonellosis].	the diagnostically and in regard to surveillance rather comprehensively recorded salmonellosis bear the character of a model of zoonotic diarrhoeal diseases. whereas those serovars predominantly adapted to human beings or animal species are without any importance in this connection, such serovars with own epizootic processes in different animal species with or without causing illness are able to be transferred to human beings via foods of animal origin and to act as etiological agents of gastroe ...	1989	2692308
[salmonella occurrence in the erfurt district].	annually in the district erfurt 7 percent of all reported diarrhoeal illnesses were microbiologically identified. salmonellosis, shigellosis and campylobacter infections dominate. between 1986 and 1987 a strong increase of salmonellosis were registered, which was caused by s. enteritidis in 70% of the cases and associated with the consumption of eggs or other products, which were manufactured from eggs contaminated with s. enteritidis.	1989	2692309
protective effect of the paf-antagonist bn 52021 on several models of gastro-intestinal mucosal damage in rats.	platelet-activating factor (paf) has been shown to induce gastro-intestinal damage similar to that evoked by endotoxin, suggesting that this mediator may be involved in the formation of gastrointestinal lesions observed in various pathologies. thus, the effects of bn 52021, a specific paf antagonist, were investigated in several experimental models of gastro-intestinal damage in rats. bn 52021 markedly reduced the gastric alterations and almost totally abolished the intestinal lesions induced by ...	1989	2693389
an outbreak of salmonella reactive arthritis in northern ireland.	during a five month period in the summer of 1987, seven cases of reactive arthritis were seen at musgrave park hospital, belfast. of the seven patients, five were male and two female. their ages ranged from 13 to 44 (mean: 26 +/- 4) years. five patients gave a preceding short history of diarrhoea which was usually mild. all patients presented with acute inflammatory oligoarthritis which predominantly affected the lower limbs. the knees were involved in 100%, the ankles in 70% with enthesopathy i ...	1989	2693394
effect of time and temperature on growth of salmonella enteritidis in experimentally inoculated eggs.	influence of time and temperature on salmonella enteritidis multiplication in experimentally injected eggs was examined. there was an increase in the number of s. enteritidis with the increase in temperature of egg storage. there was less increase of s. enteritidis in eggs stored at 4 degrees c than in eggs held at temperatures higher than 4 degrees c (p less than 0.05). these results suggest a possible method for monitoring commercial eggs for the presence of s. enteritidis. it was concluded th ...	1989	2695050
