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 ...
The use of serosurveys following emergency vaccination, to recover the status of "foot-and-mouth disease free where vaccination is not practised".
is used in limited outbreaks is it possible to test and cull comprehensively, an approach compatible with a three-month minimum period to recover the FMD-free status. In other situations, where ...
Chasing notifiable avian influenza in domestic poultry: a case report of low-pathogenic avian influenza h5 viruses in two Belgian holdings.
the H5N2 LPAI isolate was not fully adapted to these two poultry species. Our results highlighted limitations to only using serological screening for the early detection of LPAI in an ‘at-risk farm’, ...
Virulence comparison and quantification of horizontal bovine viral diarrhoea virus transmission following experimental infection in calves.
introduced to the remaining uninfected animals and produced an R of +∞ (95% CI 1.88; +∞). These results support the suggestion that TI animals, compared to PI animals, contribute only a limited amount to BVDV ...
Comparison of two real-time RT-PCR assays for differentiation of C-strain vaccinated from classical swine fever infected pigs and wild boars.
inability to differentiate infected and vaccinated animals, the so called DIVA principle. This inability complicates monitoring of disease and stops international trade thereby limiting use of the vaccine in ...
Experimental Schmallenberg virus infection of pigs.
neutralizing antibodies were found in 2 out of 4 infected piglets. The limited impact of SBV infection in pigs was further supported by the absence of neutralizing anti- SBV antibodies in field collected sera ...
Limited interlaboratory comparison of Schmallenberg virus antibody detection in serum samples.
Neutralization Tests Orthobunyavirus Sensitivity and Specificity Sheep Sheep Diseases Abstract: Eight veterinary institutes in seven different countries in Europe participated in a limited interlaboratory ...
Towards a typing strategy for Arcobacter species isolated from humans and animals and assessment of the in vitro genomic stability.
species. With a limited number of isolates to be characterized, PFGE with restriction by KpnI is proposed as the first method of choice. However, ERIC- PCR represents a more convenient genomic fingerprinting ...
Effect of a DIVA vaccine with and without in-feed use of coated calcium-butyrate on transmission of Salmonella Typhimurium in pigs.
vaccinated pigs. CONCLUSIONS: Both interventions showed a limited, non-significant reduction of Salmonella transmission between piglets. They may have applications towards Salmonella control and surveillance. ...
Development, validation and evaluation of added diagnostic value of a q(RT)-PCR for the detection of genotype A strains of small ruminant lentiviruses.
circulating in Belgium. The developed q(RT)- PCR targets a region of the gag gene and showed to be highly sensitive and specific with a limit of detection of 6 DNA and 40 RNA copies/reaction respectively. SRLV ...
