comparison of predictive models for growth of parent and green fluorescent protein-producing strains of salmonella.the green fluorescent protein (gfp) from the jellyfish aequorea victoria can be expressed in, and used to follow the fate of, salmonella in microbiologically complex ecosystems such as food. as a first step in the evaluation of gfp as a tool for the development of predictive models for naturally contaminated food, the present study was undertaken to compare the growth kinetics of parent and gfp-producing strains of salmonella. a previously established sterile chicken burger model system was used ...200312597477
studies of the phenomenon of host adaptation in salmonella.to study the phenomenon of host adaptation in salmonella, a mathematical model has been developed which permits a definition and experimental investigation of the specific interaction between the adapted serovar and the adequate host. after experimental infection using a mixture of equal parts of two salmonella strains, a and b, the bacterial concentrations ca and cb were determined in the organs of the animals infected. if an animal of species a and an animal of species b are infected with the ...200011244872
the evaluation of a live salmonella vaccine in mice and chickens.mice vaccinated with a live attenuated strain of salmonella dublin were protected against heavy challenge infections of s. dublin, s. typhimurium, s. choleraesuis and s. anatum. oral and subcutaneous vaccination were equally effective. when day-old chicks were orally vaccinated and subsequently challenged with s. typhimurium, the growth of the challenge organism was considerably reduced or eliminated from the livers of the vaccinated chicks whereas most of the non-vaccinated were heavily infecte ...19714933061
fate of unirradiated salmonella in irradiated mechanically deboned chicken meat.mechanically deboned chicken meat was irradiated at 0, 1.25 and 2.50 kgy (cesium 137) and inoculated with salmonella dublin atcc 15480, salmonella enteritidis atcc 9186 or salmonella typhimurium atcc 14028. samples were then stored at 5 degrees c and 10 degrees c and were subjected to microbiological analysis directly after irradiation and inoculation (time 0), and after 24, 72, 120, 168 and 216 h of storage. samples stored at 20 degrees c were examined at time 0 and after 6, 12 and 24 h of stor ...19911790108
[protection from virulent salmonella groups b and d after the peroral immunization of chicks with a hybrid of salmonella typhimurium and salmonella dublin].chickens over 10 days old, infected orally with virulent salmonellae, were found to remain alive. histologic investigation showed the development of mild enteritis and more pronounced, lasting for more than two weeks, inflammation of the cecum, dissemination and focal lesions in the liver (granulomas, necrosis). in experiments on the oral immunization of 3-day old chickens the bivalent hybrid of s. typhimurium vaccine strain 274 and s. dublin induced only pronounced blast transformation in lymph ...19921481606
only one of the two type vi secretion systems encoded in the salmonella enterica serotype dublin genome is involved in colonization of the avian and murine hosts.the type vi secretion system (t6ss) is a virulence factor for many gram-negative bacteria. salmonella genus harbors five phylogenetically distinct t6ss loci encoded in salmonella pathogenicity islands (spis) spi-6, spi-19, spi-20, spi-21 and spi-22, which are differentially distributed among serotypes. the t6sss encoded in spi-6 and spi-19 contribute to pathogenesis of serotypes typhimurium and gallinarum in mice and chickens, respectively. salmonella dublin is a pathogen restricted to cattle wh ...201424405577
an efficient multiplex pcr-based assay as a novel tool for accurate inter-serovar discrimination of salmonella enteritidis, s. pullorum/gallinarum and s. dublin.salmonella enterica serovars enteritidis, pullorum/gallinarum, and dublin are infectious pathogens causing serious problems for pig, chicken, and cattle production, respectively. traditional serotyping for salmonella is costly and labor-intensive. here, we established a rapid multiplex pcr method to simultaneously identify three prevalent salmonella serovars enteritidis, pullorum/gallinarum, and dublin individually for the first time. the multiplex pcr-based assay focuses on three genes tcps, ly ...201728360901
