Protozoan Cysts Act as a Survival Niche and Protective Shelter for Foodborne Pathogenic Bacteria.
species-specific differences in survival periods were observed, with Salmonella enterica surviving up to 3 weeks inside amoebal cysts. Up to 53% of the cysts were infected with pathogenic bacteria, which were ...
Veal Calves Produce Less Antibodies against C. Perfringens Alpha Toxin Compared to Beef Calves.
calves. In beef calves a fluent transition from maternal to active immunity was observed for alpha toxin, whereas almost no veal calves developed active immunity. Perfringolysin antibodies significantly ...
Whole genome protein microarrays for serum profiling of immunodominant antigens of Bacillus anthracis.
unexposed controls. Anti- IAP responses were observed for both IgG and IgA in the challenged groups; however the anti- IAP IgG response was more evident in the vaccinated group and the anti- IAP IgA response ...
Role of wildlife and domestic pigs as reservoirs for hepatitis E virus (HEV): study of the infection in suids and cervids and of the susceptibility of pigs to HEV originating from wild boa
out of 29 livers from red deer, it belonged to genotype 3f. No HEV RNA was detected in red and roe deer sera. Using a multivariate logistic regression, a significant effect of age was observed: young ...
Evaluation of a hierarchical ascendant clustering process implemented in a veterinary syndromic surveillance system.
detection of aberrations in health indicators before laboratory confirmation. “MoSS-Emergences 2” (MoSS- E2), a tool for veterinary syndromic surveillance, aggregates groups of similar clinical observations ...
Comparison of sample types and analytical methods for the detection of highly campylobacter-colonized broiler flocks at different stages in the poultry meat production chain.
different methods (direct culture, qPCR, PMA-qPCR) in cecal droppings revealed significant differences, although this was not observed for cecal-content samples. Evaluation of the Singlepath(®) test on cecal ...
Extensive genetic variability linked to IS26 insertions in the fljB promoter region of atypical monophasic variants of Salmonella enterica serovar Typhimurium.
expression of the phase 2 flagellin were observed in 53 isolates. Other genetic events in the invertible region carrying the fljB promoter were observed in 2 isolates. For the remaining 4 isolates, no ...
Campylobacter carcass contamination throughout the slaughter process of Campylobacter-positive broiler batches.
in the same slaughterhouse and between slaughterhouses was observed. In slaughterhouses A, B, C and D Campylobacter counts exceeded a limit of 1000cfu/g on 50%, 56%, 78% and 11% of carcasses after ...
Diagnosis of the Lelystad strain of Porcine reproductive and respiratory syndrome virus infection in individually housed pigs: comparison between serum and oral fluid samples for viral nucleic acid and antibody detection.
the interpretation of pen-based oral fluid results. An excellent agreement between the oral fluid and serum enzyme-linked immunosorbent assay results was observed at every time point, further supporting ...
Study of the virulence of serotypes 4 and 9 of African horse sickness virus in IFNAR(-/-), Balb/C and 129 Sv/Ev mice.
(-/-) mice, fatality up to 50% was measured and significantly more clinical signs were observed in comparison with SC inoculated immunocompetent mice. The observed clinical signs were significantly more ...
