| oral immunization against experimental salmonellosis i. development of temperature-sensitive mutant vaccines. | mutant strains of salmonella enteritidis were selected for their inability to proliferate at 37 c; when exposed to this temperature, these organisms formed tangled masses of long filaments in liquid media, presumably as a result of their inability to form cross septa. the mutants were also incapable of synthesizing flagella protein. a study of the biological charateristics of the mutants indicated that in most respects they resembled the parent strain of s. enteritidis; however, they were avirul ... | 1970 | 16557726 |
| immunity to enteric infection in mice. | specific pathogen-free cd-1 mice infected orally with sublethal doses (10(4) to 10(6) viable organisms) of salmonella enteritidis rapidly developed extensive bacterial populations in the liver, spleen, and mesenteric lymph nodes. although the pathogen did not multiply extensively in the gut, the infection persisted in the intestine at between 10(4) and 10(5) viable organisms throughout the experiment. s. gallinarum was less invasive than s. enteritidis when given by mouth; s. pullorum failed to ... | 1970 | 16557723 |
| some structural and biological properties of brucella endotoxin. | hot phenol-water extraction of smooth brucella abortus and b. melitensis cells yielded a toxic fraction which was recovered from the phenol phase (fraction 5). chemically, fractions 5 from both brucella species were lipid-carbohydrate-protein-2 keto-3-deoxyoctulosonic acid complexes which were stable to heat and resistant to pronase digestion. electron micrographs of the brucella toxins were morphologically indistinguishable from those of enterobacterial endotoxins. biologically, brucella toxins ... | 1970 | 16557710 |
| characterization of lysine decarboxylase-negative strains of salmonella enterica serovar enteritidis disseminated in japan. | salmonella enterica serovar enteritidis is one of the leading causes of food-borne diseases in japan. typically, salmonella spp. test positive for lysine-decarboxylase. however, the number of isolates of serovar enteritidis without lysine-decarboxylase activity increased in japan in 2003. among 109 strains from distinct outbreaks, 10 lacked lysine-decarboxylase activity. nine of the ten lysine-decarboxylase-negative strains showed quite similar pulsed-field gel electrophoresis profiles. their ly ... | 2006 | 16553811 |
| a newly developed assay to study the minimum inhibitory concentration of satureja spinosa essential oil. | the minimum inhibitory concentration (mic) of satureja spinosa essential oil against staphylococcus aureus, escherichia coli o157:h7, listeria monocytogenes, salmonella enterica, salmonella serovar enteritidis pt4 and bacillus cereus was comparatively assessed with an established optical density method as well as a novel impedimetric method. | 2006 | 16553733 |
| natural anti-gal and salmonella-specific antibodies in bile and plasma of hens differing in diet efficiency. | specific anti-salmonella enteritidis (se) and natural anti-alpha-gal epitope (galalpha1-3galbeta-1-4glcnac-r; anti-gal) antibodies were measured in plasma sample pools and individual bile specimens obtained from hens differing in diet efficiency. more se somatic (o) and flagellar (h) antibodies were found in plasma pools from efficient hens (r-) compared with nonefficient hens (r+) after oral challenge with live se. mean titers of somatic agglutinins in bile were 2.3 in r- hens and 1.9 in r+ hen ... | 2006 | 16553272 |
| [salmonella enteritidis: an unusual meningitis agent in an adult patient]. | salmonella species may cause wide spectrum of infections changing from enterocolitis to sepsis. however, salmonella meningitis in adults is a rare but important clinical condition with a high mortality rate. in this report, a 71 years old male patient with salmonella enteritidis meningitis who was followed-up with the diagnosis of immune thrombocytopenic purpura and had been administered azothioprin and prednisolone, has been presented and similar cases in the literature have been reviewed. the ... | 2005 | 16544553 |
| detection and enumeration of salmonella enteritidis in homemade ice cream associated with an outbreak: comparison of conventional and real-time pcr methods. | salmonellosis caused by salmonella enteritidis (se) is a significant cause of foodborne illnesses in the united states. consumption of undercooked eggs and egg-containing products has been the primary risk factor for the disease. the importance of the bacterial enumeration technique has been enormously stressed because of the quantitative risk analysis of se in shell eggs. traditional enumeration methods mainly depend on slow and tedious most-probable-number (mpn) methods. therefore, specific, s ... | 2006 | 16541697 |
| optimization of ferrioxamine e concentration as effective supplementation for selective isolation of salmonella enteritidis in egg white. | utilization of ferrioxamine e (fe) as a sole source of iron distinguishes salmonella from a number of related species, including escherichia coli. fe is not able to serve as a source of iron for e. coli or the proteus-providencia-morganella group. this confers a selective advantage on salmonella enteritidis in egg white supplemented with fe. the optimum concentration of fe that promoted a selective advantage for salmonella in egg white was determined. four supplementation concentrations were eva ... | 2006 | 16541696 |
| reduction of salmonella enterica serovar enteritidis on the surface of raw shelled almonds by exposure to steam. | this study was conducted to investigate the effect of steam treatment on the reduction of salmonella enterica serovar enteritidis on the surface of raw almonds. two cultivars, 'nonpareil' and 'mission', were studied. salmonella enteritidis was inoculated on the surface of raw almonds, which were then treated with steam (93 degrees c +/- 1 degrees c) for 5, 15, 25, 35, 45, 55, and 65 s. after steam treatment, samples were plated on xylose lysine desoxycholate (xld) and overlay (ov) xld as a selec ... | 2006 | 16541690 |

| evaluation of eggshell quality of hens infected with salmonella enteritidis by application of compression. | eggs collected from hens of different ages and that differed in infection status with salmonella enteritidis were evaluated for the ability to resist cracking following application of maximum compression load from an instron materials testing machine. orally infected 24-wk-old hens that were prepeak produced eggs with significantly lower hardness units (hu) of shells compared with a paired control group (p < or = 0.01). however, 1 of 3 additional infection trials in hens at peak (29 wk) and olde ... | 2006 | 16493956 |
| individual differences in glucose homeostasis: do our early life interactions with bacteria matter? | exposure to endotoxin during the neonatal period in the rat has been shown to alter the development of the hypothalamic-pituitary-adrenal axis, inducing hyper-responsivity and increased glucocorticoid production in later-life. glucocorticoids are known to have major metabolic effects, therefore, early life endotoxin exposure may have potentially serious consequences for metabolic homeostasis in the exposed animal. the aims of this study were therefore to assess the effect of neonatal bacterial e ... | 2006 | 16480850 |
| recovery of salmonella from commercial shell eggs by shell rinse and shell crush methodologies. | salmonella is the most important human pathogen associated with shell eggs. salmonella enteritidis is the serotype most often implicated in outbreaks, although other serotypes have been recovered from eggs and from the commercial shell egg washing environment. many sample methods are used to recover microorganisms from eggshells and membranes. a shell rinse and modified shell-and-membrane crush method for recovery of salmonella were compared. eggs were collected from 3 commercial shell-washing f ... | 2005 | 16479955 |
| supplementation of coated butyric acid in the feed reduces colonization and shedding of salmonella in poultry. | short-chain fatty acids have been widely used as feed additives to control salmonella in poultry. data on the use of butyric acid in poultry are lacking. in this study, powder form and coated butyric acid were compared in their ability to reduce salmonella colonization of ceca and internal organs shortly after infection of young chickens with salmonella enteritidis. in the first trial, 4 groups of 25 specific pathogen free layer chickens were given feed either supplemented with powder form butyr ... | 2005 | 16479940 |
| identification of genes associated with survival of salmonella enterica serovar enteritidis in chicken egg albumen. | salmonella enterica consists of over 2,000 serovars that are major causes of morbidity and mortality associated with contaminated food. despite similarities among serovars of salmonella enterica, many demonstrate unique host specificities, epidemiological characteristics, and clinical manifestations. one of the unique epidemiological characteristics of the serovar enteritidis is that it is the only bacterium routinely transmitted to humans through intact chicken eggs. therefore, salmonella enter ... | 2006 | 16461649 |
| comparison of effects of high-pressure processing and heat treatment on immunoactivity of bovine milk immunoglobulin g in enriched soymilk under equivalent microbial inactivation levels. | immunoglobulin-rich foods may provide health benefits to consumers. to extend the refrigerated shelf life of functional foods enriched with bovine immunoglobulin g (igg), nonthermal alternatives such as high-pressure processing (hpp) may offer advantages to thermal processing for microbial reduction. to evaluate the effects of hpp on the immunoactivity of bovine igg, a soymilk product enriched with milk protein concentrates, derived from dairy cows that were hyperimmunized with 26 human pathogen ... | 2006 | 16448177 |
| a novel transposon-based method for elimination of large bacterial plasmids. | elimination or modification of large plasmids of bacteria is often an essential step in functional analysis of these replicons. however, the conventional plasmid-curing procedures such as ethidium bromide and heat treatment are insufficient in many cases. for instance, curing of the large virulence plasmid of salmonella enteritidis 2,102 has failed when these treatments were applied. to overcome the difficulties, a two-step transposon-based curing method has been developed. first, a tn10-based t ... | 2006 | 16439018 |
