| effects of medium-chain fatty acids on the structure and immune response of ipec-j2 cells. | medium-chain fatty acids (mcfas) have been suggested as an alternative to the use of antibiotics in animal nutrition with promising results. first, we studied the sensitivity of salmonella enteritidis and an enteropathogenic escherichia coli strain against caprylic (c8), capric (c10) and lauric (c12) acids. a porcine in vitro model using the porcine cell line ipec-j2 was used to test the effects of mcfas on structural and immunological traits without and with a concomitant challenge with e. coli ... | 2016 | 27553650 |
| distinct salmonella enteritidis lineages associated with enterocolitis in high-income settings and invasive disease in low-income settings. | an epidemiological paradox surrounds salmonella enterica serovar enteritidis. in high-income settings, it has been responsible for an epidemic of poultry-associated, self-limiting enterocolitis, whereas in sub-saharan africa it is a major cause of invasive nontyphoidal salmonella disease, associated with high case fatality. by whole-genome sequence analysis of 675 isolates of s. enteritidis from 45 countries, we show the existence of a global epidemic clade and two new clades of s. enteritidis t ... | 2016 | 27548315 |

| in vitro invasive capacity of salmonella strains into sections of the layer hen oviduct. | raw or undercooked eggs and egg products are frequently identified as the source of salmonella following outbreaks of foodborne gastrointestinal disease. some salmonella serovars, such as salmonella enteriditis, have a high tropism for the oviduct of laying hens. oviduct colonization with s. enteriditis can result in both internal and external contamination of an egg. while oviduct invasion is not limited to s. enteriditis, the invasive capacities of other serovars is not widely known. in this s ... | 2016 | 27527775 |
| [investigation of antitumorigenic effects of food-borne non-pathogenic and pathogenic salmonella enterica strains on mef, du145 and hela cell lines]. | basic applications in cancer therapy may fail to eradicate cancer cells completely, they can show toxic affects to healthy cells and development of resistance to antitumor agents may increase tendency to metastasis. bacterial therapies have the advantage of specific targetting of tumors by selective toxicity, responsiveness to external signals, self-propelling capacity, and the sense of microenvironment. the most interest on the bacterial cancer therapy is about salmonella spp. with a special em ... | 2016 | 27525394 |

| a curious cause of appendicitis. | a previously healthy 10-year-old boy presented to the emergency department with central abdominal pain, loose stool and vomiting. he was diagnosed with gastroenteritis, but was well enough to be discharged. the next day he reattended with ongoing diarrhoea and vomiting, with the pain now localised to the right iliac fossa (rif). acute appendicitis was suspected, and he was taken for laparoscopic appendicectomy. at surgery, a gangrenous appendix was found, with pus extending from the pelvis up to ... | 2016 | 27489071 |
| combination of competitive exclusion and immunisation with a live salmonella vaccine in newly hatched chickens: immunological and microbiological effects. | in addition to evaluating the efficacy potential of a combined use of vaccination and competitive exclusion (ce) against salmonella exposure in chicks at 3-days of age, a live salmonella enteritidis vaccine (se-lv) and a ce culture were tested for their ability to induce parameters of the innate immunity. whereas the invasive se-lv induced an influx of granulocytes and macrophages as well as an increased transcription of several cytokines in the caecal mucosa, the ce culture did not demonstrate ... | 2016 | 27473972 |
| chicken-specific kinome array reveals that salmonella enterica serovar enteritidis modulates host immune signaling pathways in the cecum to establish a persistence infection. | non-typhoidal salmonella enterica induces an early, short-lived pro-inflammatory response in chickens that is asymptomatic of clinical disease and results in a persistent colonization of the gastrointestinal (gi) tract that transmits infections to naïve hosts via fecal shedding of bacteria. the underlying mechanisms that control this persistent colonization of the ceca of chickens by salmonella are only beginning to be elucidated. we hypothesize that alteration of host signaling pathways mediate ... | 2016 | 27472318 |
