| invasion of salmonella enteritidis in avian intestinal epithelial cells in vitro is influenced by short-chain fatty acids. | fermentation reactions in the caeca of chickens, the predominant place for salmonella colonization, result in high concentrations of short-chain fatty acids (scfa). thus salmonella bacteria are in close contact with scfa during their life cycle. a study was carried out to analyse the effects of scfa on invasion of salmonella enteritidis in an avian intestinal epithelial cell line. preincubation of s. enteritidis for 4 h in growth media supplemented with various concentrations of propionate or bu ... | 2003 | 12878382 |
| survival of foodborne pathogens on stainless steel surfaces and cross-contamination to foods. | the retention of bacteria on food contact surfaces increases the risk of cross-contamination of these microorganisms to food. the risk has been considered to be lowered when the surfaces are dry, partly because bacterial growth and survival would be reduced. however, some non-spore-forming bacteria might be able to withstand dry conditions on surfaces for an extensive period of time. in this study the survival of salmonella enteritidis, staphylococcus aureus and campylobacter jejuni on stainless ... | 2003 | 12878381 |
| invasion of salmonella enteritidis in the tissues of reproductive organs in laying japanese quail: an immunocytochemical study. | the aim of this study was to determine whether salmonella enteritidis (se) inoculated into the peritoneal cavity would colonize tissues of reproductive organs in japanese quail hens. quail hens regularly laying were intraperitoneally inoculated with 5 x 10(7) or 5 x 10(8) se cells, and the ovary, oviduct, kidney, spleen, liver, and large intestine were excised 24 or 48 h after the treatment. paraffin sections of these organs were immunostained for se. invasion of se was found in the tissues of t ... | 2003 | 12872975 |
| evaluation of treatment and prophylaxis with nitrofurans and comparison with alternative antimicrobial agents in experimental salmonella enterica serovar enteritidis infection in chicks. | the ability of the nitrofuran antimicrobial agents furazolidone and furaltadone to prevent, reduce or eliminate salmonella enterica serovar enteritidis pt4 infection in artificially challenged day-old chicks was evaluated. treating the birds with the nitrofurans failed to eliminate established infections with either furazolidone-resistant (fzr) or furazolidone-sensitive (fzs) strains. simultaneous administration of the nitrofurans to day-old chicks challenged with fzs failed to prevent infection ... | 2003 | 12872826 |

| prevalence and antibiotic susceptibility of salmonella isolated from foods in korea from 1993 to 2001. | this study determined the prevalence of salmonella in foods widely consumed in korea from 1993 to 2001, along with antimicrobial susceptibility profiles of salmonella isolates from these foods for 11 antibiotics. overall, 41 salmonella isolates, representing 15 serotypes, were obtained from 2.2% (29 of 1,334) of the samples examined, and most of the salmonella isolates were recovered from broiler carcasses. the most common serotypes were salmonella enteritidis (29.3%), salmonella virginia (14.6% ... | 2003 | 12870747 |
| [aetiology and antibiotic sensitivity of the most frequent outpatient infections, except those of the lower respiratory tract]. | reporting of antimicrobial susceptibility profiles is recommended in order to improve antibiotic prescribing policies and to avoid the emergence of bacterial resistance. during 2001, susceptibility data from bacterial isolates collected from urine, faeces and ear swabs and antimicrobial susceptibility for streptococcus pyogenes during the first five months in 2002 were recorded in the health area of pamplona (389,489 inhabitants) and compared against data for antibiotic prescriptions. more than ... | 2002 | 12861284 |
| differential regulation of cytokine gene expression by avian heterophils during receptor-mediated phagocytosis of opsonized and nonopsonized salmonella enteritidis. | internalization of pathogens by phagocytic cells triggers the innate immune response, which in turn regulates the acquired response. phagocytes express a variety of receptors that are involved in recognition of pathogens, including (1) pattern recognition receptors (prr), which recognize conserved motifs, (2) complement receptors (cr), which recognize complement-opsonized pathogens, and (3) fc receptors (fcr), which recognize antibody-opsonized pathogens. recognition of microbes is accompanied b ... | 2003 | 12859858 |
| application of an automated immunomagnetic separation-enzyme immunoassay for the detection of salmonella spp during an outbreak associated with a retail premises. | the application of an automated immunomagnetic separation-enzyme immunoassay (aims-eia) during the investigation of a suspected outbreak of salmonella food poisoning at a retail premises. | 2003 | 12859657 |
| md-1 is a critical part of the mechanism causing th1-cytokine-triggered murine fetal loss syndrome. | fetal loss syndrome (abortion/resorption) occurring on or after gestation day (gd) 9.5 in cba/jxdba/2 matings is dependent upon presence of tnf-alpha + ifn-gamma, which act by increasing expression of fg12 prothrombinase at the feto-maternal interface. the magnitude by which the abortion rate can be boosted by an injection of these cytokines on gd 7.5 depends on endogenous rate of loss, and appears to depend on microbial flora. is cytokine-triggered abortion dependent upon a third signaling path ... | 2003 | 12854734 |
| [salmonella infection complicated with acute renal failure]. | acute renal failure is a known complication to salmonella gastroenteritis, and patients with chronic renal failure or impaired host defence are at increased risk. in the two presented cases there had been a few days of gastroenteritis before the hospitalisation, but the only symptoms at the admission were fatigue and dyspnoea. in both cases severe uraemia had developed and the patients and their physicians did not expect the episode of gastroenteritis to be the only etiology of acute renal failu ... | 2003 | 12854271 |
