| salmonella infection increases porcine antibacterial peptide concentrations in serum. | pr-39 is a multifunctional neutrophil peptide involved in host defense and inflammation. to investigate the involvement of pr-39 in a salmonella choleraesuis infection, a pr-39 enzyme immunoassay was developed. the concentrations of pr-39 in serum were 13.6 +/- 1.9 ng/ml before challenge and increased (p < 0.01) threefold by 10 to 14 days postinfection. peripheral blood neutrophil counts paralleled the changes in the concentrations of pr-39 in serum, both returned to basal values by 4 weeks post ... | 1997 | 9384306 |
| phage types of salmonella enterica serovar enteritidis isolated in south africa from 1991-1995. | a total of 615 strains of salmonella enterica serovar enteritidis (se), received from 1991-1995 at the onderstepoort veterinary institute (ovi), were phage typed. most se isolates (54,7%) originated from poultry followed by humans (28,5 %) and poultry eggs (9,6 %). phage type 34 was the most prevalent (40,5 %) of all isolates, followed by phage type 4 (33,8 %). other phage types identified were 1, lb, 4a, 7, 7a, 9a, 14, 24, 24var and 35 (in total 2,4% of isolates). most isolates of se were recei ... | 2000 | 11028749 |
| reducing mortality in salmonella enterica serovar typhimurium-infected mice with a tripeptidic serum fraction. | salmonellosis-induced mortality in female swiss webster mice decreased significantly when tripeptidic immunostimulant (tpi) was administered prophylactically. prophylactic benefits developed in a dose-dependent manner wherein 15 mg of tpi given 1 day before challenge reduced mortality by 70%. | 2002 | 12019117 |
| haemolysins of salmonella, their role in pathogenesis and subtyping of salmonella serovars. | haemolysin patterns of 175 strains of different salmonella enterica subspecies enterica serovars isolated from different animal sources and places were determined using 11 different blood agar media made with either non-washed horse/sheep erythrocytes or with washed erythrocytes of cattle, sheep, horse, goat, rabbit, guinea pig, and human a, o and b blood groups. study on 47 strains belonging to 10 serovars of salmonella from buffalo meat (buffen), 42 strains of 11 serovars from goat meat (chevo ... | 2004 | 15233302 |
| novel haemolysins of salmonella enterica spp. enterica serovar gallinarum. | haemolysins of salmonella are important due to their probable role in pathogenesis of systemic salmonellosis and use in sub-serovar level typing. the present study was undertaken to determine haemolytic potential of salmonella gallinarum strains through phenotypic and genotypic methods. amplification of haemolysin gene (clya) and cytolysin gene (slya) was attempted in order to determine their role in haemolysin production. study on 94 strains of s. gallinarum revealed the production of two types ... | 2005 | 16053269 |
| detection of pathogens in ovine and caprine abortion samples from sardinia, italy, by pcr. | during 2003-2005, 399 abortion samples (315 fetuses and 84 placentae) were collected from 107 ovine and caprine farms in northern sardinia. tissues from aborted fetuses and placentae were examined by pcr assay to detect dna from coxiella burnetii, chlamydophila abortus, salmonella enterica serovar abortusovis, toxoplasma gondii, and neospora caninum. the dna from at least 1 of these 5 infectious agents was amplified in 41% of ovine fetuses, while only 17% of the caprine fetuses yielded a positiv ... | 2007 | 17459840 |
| diseases and reproductive success in a wild mammal: example in the alpine chamois. | density-dependent and climatic factors affect reproduction and dynamics of wild ungulates. parasites can also decrease reproductive success through either a direct abortive effect or a negative impact on host growth and body condition. however, few studies have investigated the effect of parasitism on fecundity of ungulates in natural conditions. we studied three bacterial infections caused by salmonella enterica serovar abortusovis, chlamydophila abortus and coxiella burnetii. these bacteria ar ... | 2008 | 18189146 |
| outbreak of salmonella enterica serotype muenster infections associated with goat's cheese, france, march 2008. | salmonella enterica serotype muenster (hereafter referred to as s. muenster) is rare in france and in europe. in france, a nationwide outbreak of gastrointestinal illness due to s. muenster occurred during march and april 2008. twenty-five laboratory-confirmed cases of s. muenster were documented by telephone using a trawling questionnaire. four patients were admitted to hospital and no death was recorded. among the 21 interviewed cases, 16 reported consumption of goat's cheese in the days prior ... | 2009 | 19660242 |
| evaluation of aroa deletion mutant of salmonella enterica subspecies enterica serovar abortusequi for its vaccine candidate potential. | the present study on a defined deletion aroa mutant (b-26) of salmonella enterica subspecies enterica serovar abortusequi (s. abortusequi) for residual virulence and safety in experimental model revealed that the virulence of the strain was at no difference in any of the cell assays (caprine alveolar macrophages, bovine alveolar macrophages, guinea pig blood mononuclear cells and horse blood mononuclear cells) than that of its parent virulence plasmid cured (s-787) and wild type (e-156) strains. ... | 2009 | 20099460 |
