depressed liver regeneration after partial hepatectomy of germ-free, athymic and lipopolysaccharide-resistant mice.a hypothesis has been proposed by this laboratory that endogenous gut-derived lipopolysaccharide is responsible for systemic endotoxemia in animals with acute liver injury particularly after partial (67%) hepatectomy. systemic lipopolysaccharide and possibly fibrin aggregates or tissue debris then elicit release of cytokines from phagocytizing macrophages and/or monocytes that may be essential for normal liver regeneration. to test this hypothesis liver regeneration was assessed in germ-free eut ...19902194922
viability of salmonella in bone meal.the ability of salmonella to survive varying concentrations of sodium metabisulphite incorporated into bone meal (rendered animal by-product) was investigated. no viable salmonella was detected after 4 days of exposure of the micro-organisms to 5,000 ppm of sodium metabisulphite. the minimum killing concentration of metabisulphite was also established at 4,000 ppm. however, the killing effect of the metabisulphite was moisture-dependent, being most potent at a moisture level of 8 to 12%.19902195301
production of salmonella enteritidis-contaminated eggs by experimentally infected hens.laying hens of three different ages were experimentally infected with a strain of salmonella enteritidis by either oral inoculation or contact transmission. total egg production was depressed in exposed hens of all three age groups. persistent intestinal shedding was observed in a small number of hens. eggs with contents contaminated by s. enteritidis were produced by exposed hens at a high frequency, but only during a fairly short period of time that extended through approximately 1 week postin ...19902196046

[bavaroise and an epidemic of salmonella enteritidis].in the literature an association is made between the increasing prevalence of salmonella enteritidis in poultry products and in the isolates of patients with gastroenteritis, without sufficient evidence of a causal relationship between the increasing prevalences. a microbiological and epidemiological analysis of a food poisoning incident among 239 visitors of a restaurant by way of food specific attack rates and food specific infection rates revealed an epidemic of 70 cases of s. enteritidis ent ...19902196469
[primary abscess of the psoas].we present in this paper a series of cases from our service of primary abscesses in psoas. we consider the appearance of immunosuppressed patients as a relevant factor of its etiopathogenicity. we believe that a c.a.t. is the best diagnostic method. all three patients that underwent open surgery have had complications. the patients treated with percutaneous puncture has shown a favourable evolution.19902198765
multiple drug resistance in salmonellae in england and wales: a comparison between 1981 and 1988.each year from 1981 through to 1988 the most common serotypes isolated from man in england and wales and identified at the division of enteric pathogens were s typhimurium, s enteritidis, and s virchow. in 1981 these three serotypes accounted for 45%, 12%, and 7% of isolations. the remaining 35% comprised strains belonging to a further 188 different serotypes, none of which accounted for more than 1% of the total. in 1988 s typhimurium accounted for 24% of isolations, s enteritidis 57%, and s vi ...19902199536
international increase in salmonella enteritidis: a new pandemic?over the past 5 years salmonella enteritidis infections in humans have increased on both sides of the atlantic ocean. the who salmonella surveillance data for 1979-87 were reviewed and show that s. enteritidis appears to be increasing on at least the continents of north america, south america, and europe, and may include africa. s. enteritidis isolates increased in 24 (69%) of 35 countries between 1979 and 1987. in 1979, only 2 (10%) of 21 countries with reported data reported s. enteritidis as ...19902200698
[preliminary results of the determination of plasmid profiles of veterinary salmonella isolates].a plasmid of 60 md magnitude was recorded from 40 in 41 salmonella (s.) typhimurium strains, including the copenhagen minus variant. a plasmid of that kind had been described in the international literature as serovar-specific of s. typhimurium. one s. typhimurium strain was without plasmid. five contained the 60-md and other plasmids. no relationship was found to exist between the 60-md plasmid and biovar as well as chemotherapeutic resistance. further studies will be necessary for consistent i ...19902201272

enhancement of antigonadotropin response to the beta-subunit of ovine luteinizing hormone by carrier conjugation and combination with the beta-subunit of human chorionic gonadotropin.previous studies have demonstrated the control of fertility in monkeys on immunization with the beta subunit of ovine luteinizing hormone (beta-olh) along with freund's complete adjuvant (cfa). an eventual birth control vaccine would demand immunization without cfa. beta-olh linked to tetanus toxoid (tt) adsorbed on alum-induced antibody response in bonnet monkeys with detoxified sodium phthalyl derivative of salmonella enteritidis lipopolysaccharide added only in the first injection. the antibo ...19862424791
improvement in organ blood flow by inhibition of thromboxane synthetase during experimental endotoxic shock in the rat.endotoxic shock is associated with increased metabolism of arachidonic acid to thromboxane (tx) and prostaglandins. this investigation examined the effects of two structurally dissimilar inhibitors of (tx) synthetase on salmonella enteritidis endotoxin (lps) (15 mg/kg)-induced alterations in cardiac output and organ blood flow in long-evans rats. an imidazole derivative, 7(1-imidazolyl) heptanoic acid (7-iha), and sodium -(e)-3-[4-(3-pyridyl-methyl)phenyl]-2-methacrylate (oky-1581) were injected ...19862425166
[effect of the cultivation temperature on the production of biomass and lipopolysaccharide as well as the chemical composition and antigenicity of the lipopolysaccharide of s-forms and r-mutants of the genus salmonella].the effect of different temperatures (30 to 43 degrees c) on salmonella s forms and r mutants in fermentor mass cultures was studied. it was found that for the velocity of substrate utilization, for maximum lps biosynthesis as well as for maximum biosynthesis of bacterial cell-mass the respective optimum temperature was different. in the case of s-form strains and of one sr mutant a cultivation temperature of 34 degrees c proved optimum for maximum yield of lps. at this temperature the yield of ...19862426871
regulation of cell-mediated immunity in mice immunised with salmonella enteritidis.the effects of diverse factors, such as route of immunisation, composition of immunogen and administration of interferon inducer, on the expression of cell-mediated immune responses against salmonella enteritidis were investigated in balb/c and swiss white mice. immunisation with live cells of s. enteritidis by the intraperitoneal route (ip) generated both delayed type hypersensitivity (dth) and protective cell-mediated immunity (cmi). however, the two responses showed diametrically opposite tim ...19872438409
thermal stimulation of the hypothalamus does not evoke the acute-phase reaction.interleukin-1 (il1) injected into the preoptic-anterior hypothalamus (poah) induces, besides fever, the hepatic synthesis of acute-phase glycoproteins. since the febrigenic action of il1 may involve thermosensitive neurons in the poah, this study examined whether such neurons also might mediate the acute-phase response (apr). the poah of six adult nzw rabbits was cooled (tpo = 34.4 +/- 0.4 degrees c [mean +/- sd]) or heated (40.6 +/- 0.2 degrees c) continuously for 2.5 hr (so as to mimic the mea ...19872443224
immunoblot analysis of salmonella typhi lipopolysaccharide (lps) using typhoid sera.lipopolysaccharide (lps) of salmonella typhi has been analyzed by immunoblotting with pooled sera from typhoid patients. pooled typhoid sera have recognized all the antigenic determinants of s. typhi lps, giving a strong reaction with the repeating units on the o-side chains as well as with the core region. cross-reacting antigens have been observed with the lps of s. typhimurium and s. enteritidis, while no heterologous reactions were seen with the lps of e. coli strains.19872444235
monoclonal antibodies delineate multiple epitopes on the o antigens of salmonella typhi lipopolysaccharide.fifteen monoclonal antibodies (mabs) directed against salmonella typhi were produced and characterized. the specificities of the antibodies were determined by their binding patterns in an enzyme immunoassay, with a panel of lipopolysaccharides isolated from different bacteria. seven mabs reacted with s. typhi, salmonella enteritidis, and salmonella dublin (all belonging to serogroup d). one mab also reacted with salmonella paratyphi a and s. paratyphi b. five mabs reacted with s. typhi, s. enter ...19882466868
bactericidal activity of human sera with a physiologic or genetic defect of the complement system.the serum of patient suffering genetically conditioned c2 defect showed a weak bactericidal activity against pseudomonas aeruginosa strains. out of 23 tested strains one was susceptible comparing with 16 ones sensitive to normal human serum. the normal cord serum exerted a bactericidal effect on 8 strains. all sera were found to be active against salmonella strains tested.19882470241
route-related variation in the immunogenicity of killed salmonella enteritidis vaccine: role of antigen presenting cells.in order to assess the role of the route of immunization on the immunogenicity of killed salmonella vaccine, mice were immunized with killed s. enteritidis by intraperitoneal (i.p.) and intradermal (i.d.) routes. whereas the former was non-immunogenic, the i.d. immunization generated an excellent delayed-type hypersensitivity response; further, i.p. immunization could even suppress the subsequent i.d. immunization. since the peritoneal macrophages (mo) are known to be particularly low in ia or m ...19892475750
effect of detoxification processes on the interferon-inducing activity of bacterial endotoxins.the interferon (ifn)-inducing activity of detoxified lipopolysaccharide (lps) was tested in rabbits treated with lps preparation derived from escherichia coli, salmonella typhi, salmonella enteritidis and shigella dysenteriae serovar 1. of the detoxification procedures used, alkaline hydrolysis, hydroxylaminolysis, formalization, treatment with sodium deoxycholate and the radiodetoxification (fast or slow) methods had no appreciable effects on the ifn-inducing potential of lps. in contrast, acet ...19892484274
