| salmonella stress management and its relevance to behaviour during intestinal colonisation and infection. | the enteric pathogen salmonella enterica is exposed to a number of stressful environments during its life cycle within and outside its various hosts. during intestinal colonisation salmonella is successively exposed to acid ph in the stomach, to the detergent-like activity of bile, to decreasing oxygen supply, to the presence of multiple metabolites produced by the normal gut microflora and finally it is exposed to cationic antimicrobial peptides present on the surface of epithelial cells. there ... | 2005 | 16023758 |
| differential responses of macrophages to salmonella enterica serovars enteritidis and typhimurium. | macrophages are major effectors against salmonella infection, and also transport bacteria between host tissues and provide a protected site for intracellular bacterial replication. we hypothesized that differences in chicken macrophage responses to salmonella enterica serovar enteritidis (se) and serovar typhimurium (st) played a role in preferential infection of eggs by se compared with st. to test this hypothesis, we determined bacterial phagocytosis and intracellular viability and macrophage ... | 2005 | 16023220 |
| dyspepsia and irritable bowel syndrome after a salmonella gastroenteritis outbreak: one-year follow-up cohort study. | it has been reported that some patients develop functional digestive disorders, particularly irritable bowel syndrome (ibs), after acute gastroenteritis (age). however, the presence of dyspepsia has not been specifically addressed. we prospectively evaluated development of dyspepsia and ibs during a 1-year follow-up in a cohort of adult patients affected by a salmonella enteritidis age outbreak. | 2005 | 16012939 |
| rapid decay of salmonella flagella antibodies during human gastroenteritis: a follow up study. | an indirect enzyme-linked immunosorbent assay (elisa) based on salmonella re-polymerized flagella was employed to measure levels of immunoglobulin (ig) g, igm and iga antibodies in sera from 303 danish patients diagnosed with either salmonella enteritidis or salmonella typhimurium. the antibody-levels were assessed at one, three and six months after onset of salmonellosis, and sera from a control-group of 170 healthy blood donors were additionally analysed in order to establish cut-off values fo ... | 2005 | 16009280 |
| pheno-genotyping of salmonella enterica serotype enteritidis isolates identified in sicily during a reemergence period. | after an upward trend paralleling that occurring in most european countries, including italy, since october 2002 salmonella enterica serotype enteritidis (s. enteritidis) has again gained the first position among outbreak and sporadic human isolates of salmonella in sicily. because phage typing of s. enteritidis has many technical and epidemiological limitations and molecular methods have proved to be poorly discriminative for this organism, multiple typing, using phage typing together with puls ... | 2004 | 15992280 |
| aetiology and pathogenesis of reactive arthritis: role of non-antigen-presenting effects of hla-b27. | spondyloarthropathies are inflammatory diseases closely associated with human leukocyte antigen (hla)-b27 by unknown mechanisms. one of these diseases is reactive arthritis (rea), which is typically triggered by gram-negative bacteria, which have lipopolysaccharide as an integral component of their outer membrane. several findings in vivo and in vitro obtained from patients with rea and from different model systems suggest that hla-b27 modulates the interaction between rea-triggering bacteria an ... | 2005 | 15987495 |

| development of a pcr system for the characterisation of salmonella flagellin genes. | analysis of flagellin genes was carried out on strains of salmonella typhimurium, salmonella hadar, salmonella abortusequi, salmonella enteritidis and salmonella gallinarum serovars, using a pcr system designed in this study. the purpose of these studies was to explore the flagellin genes of biphasic and monophasic salmonellae for future targeted genetic interventions. the pcr primers were designed for two different structural genes of flagellin (flic, fljb), for the repressor of flic (flja), fo ... | 2005 | 15959975 |
| anti-inflammatory properties of heat shock protein 70 and butyrate on salmonella-induced interleukin-8 secretion in enterocyte-like caco-2 cells. | intestinal epithelial cells secrete the chemokine interleukin (il)-8 in the course of inflammation. because heat shock proteins (hsps) and butyrate confer protection to enterocytes, we investigated whether they modulate salmonella enterica serovar enteritidis (s. serovar enteritidis)-induced secretion of il-8 in enterocyte-like caco-2 cells. caco-2 cells incubated with or without butyrate (0-20 m m, 48 h) were infected with s. serovar enteritidis after (1 h at 42 degrees c, 6 h at 37 degrees c) ... | 2005 | 15958071 |
| growth of salmonella in egg white. | six non-s. enteritidis strains and eleven s. enteritidis strains of which 8 were isolated from eggs, were tested on their growth behaviour in fresh eggs and in eggs of 2 and 3 weeks old hold at 20 degrees c. the growth of salmonella at 20 degrees c was measured at days 6, 13 and 23 after inoculation. taking the average growth of the different s. enteritidis and of the non-s. enteritidis strains, we found that both groups grew very well in fresh eggs. s. enteritidis strains grew as good in eggs o ... | 2001 | 15954649 |
| endotoxin releases a substance from the aorta that dilates an isolated arteriole by up-regulating inos. | loss of vascular tone in resistance arterioles has been implicated as the cause of hypotension in septic shock. it is believed that the overproduction of nitric oxide (no) by the inducible isoform of nitric oxide synthase (inos) results in the vasodilatation seen in septic shock. however, we have shown that endotoxin has no effect on vascular tone of an isolated resistance vessel unless the endotoxin flows over a segment of aorta or vena cava upstream in the superfusion line. the aim of this stu ... | 2005 | 15921695 |
| identification of ctx-m-14 {beta}-lactamase in a salmonella enterica serovar enteritidis isolate from japan. | we analyzed the resistance to cefotaxime of a salmonella enterica serovar enteritidis isolate from a stool culture of a 4-year-old boy. it produced a beta-lactamase ctx-m-14, encoded by two related r plasmids. the region surrounding the blactx-m-14 gene had an original mosaic structure containing insertion sequences (is26 and is903d). | 2005 | 15917576 |
| ovarian laying hen follicular maturation and in vitro salmonella internalization. | transovarian transmission of paratyphoid salmonella is well documented and occurs at a low incidence in chickens. however, the exact mechanism of follicular invasion is not well understood. the following study investigates the ability of salmonella to invade ovarian follicles at different stages of follicular maturity in vitro. ovarian follicles were collected from leghorn hens and separated into three stages of maturity: (1) large yellow follicles or f follicles (lyf), (2) small yellow follicle ... | 2005 | 15917137 |
| application of sybr green real-time pcr assay for specific detection of salmonella spp. in dairy farm environmental samples. | the objective of this study was to develop and evaluate a sybr green 1 real-time pcr method for the specific detection of salmonella spp. in dairy farm environmental samples. previously reported 119-bp inva gene was selected for specificity, and 124 salmonella spp. including type strains and 116 non-salmonella strains were evaluated. all salmonella strains tested were inva-positive and all non-salmonella strains yielded no amplification products. the melting temperature (tm=79 degrees c) was con ... | 2005 | 15913820 |
| identification of antiadhesive fraction(s) in nonimmunized egg yolk powder: in vitro study. | the presence of antiadhesive component(s) in the hen egg yolk against foodborne pathogens was anticipated from results of a previous animal study conducted by the authors. the previous work showed egg yolk powder without specific antibodies is effective in controlling salmonella enteritidis,salmonella typhimurium, and escherichia coli o157:h7 colonization in laying hens. therefore, this study was necessary to locate the activity and identify the effective component(s). in vitro experiments were ... | 2005 | 15913333 |

| clonal expansion may account for high levels of quinolone resistance in salmonella enterica serovar enteritidis. | we have observed a high incidence of isolated nalidixic acid resistance in salmonella enterica serovar enteritidis isolates in ireland, particularly isolates of phage type 1 (pt1). a group of nalidixic acid-resistant (n = 22) and nalidixic acid-susceptible (n = 28) isolates of serovar enteritidis from multiple sites in ireland were selected. isolates were typed by pulsed-field gel electrophoresis (pfge) with xbai, and the mics for nalidixic acid and ciprofloxacin were determined. mutations assoc ... | 2005 | 15870349 |
| potential role of diploscapter sp. strain lkc25, a bacterivorous nematode from soil, as a vector of food-borne pathogenic bacteria to preharvest fruits and vegetables. | diploscapter, a thermotolerant, free-living soil bacterial-feeding nematode commonly found in compost, sewage, and agricultural soil in the united states, was studied to determine its potential role as a vehicle of salmonella enterica serotype poona, enterohemorrhagic escherichia coli o157:h7, and listeria monocytogenes in contaminating preharvest fruits and vegetables. the ability of diploscapter sp. strain lkc25 to survive on agar media, in cow manure, and in composted turkey manure and to be ... | 2005 | 15870330 |
| recombinant chicken il-6 does not activate heterophils isolated from day-old chickens in vitro. | pro-inflammatory cytokines are produced as part of innate immunity. increased resistance to extraintestinal salmonella enteritidis (se) has been associated with an increase in heterophil pro-inflammatory cytokine gene expression. invasion of chicken epithelial cells by se induces an 8- to 10-fold increase in interleukin (il) -6 production. infection with se induces an influx of heterophils to the site of infection; therefore, we hypothesize heterophils would be responsive to il-6. the objective ... | 2005 | 15859240 |
| individual-based modelling of growth and migration of salmonella enteritidis in hens' eggs. | an individual-based model (ibm) was developed to describe the growth and migration of salmonella enteritidis in hens' eggs. the bacteria simulator (bacsim) environment was used to implement the model; the bacteria are represented by spheres that grow by nutrient uptake and divide in two daughter cells upon exceeding a certain threshold volume. motility of the salmonella bacteria was described by a run and tumble mechanism. for the sake of simplicity, the bacteria were assumed to grow exponential ... | 2004 | 15854715 |
