Effectiveness and Cost Efficiency of Different Surveillance Components for Proving Freedom and Early Detection of Disease: Bluetongue Serotype 8 in Cattle as Case Study for Belgium, France and the Netherlands.
influential parameters for proving freedom and early detection. Looking at the assumed direct costs, although total costs were low for sentinel and passive clinical surveillance components, passive clinical ...
Quantification of rHVT-F genome load in feather follicles by specific real-time qPCR as an indicator of NDV-specific humoral immunity induced by day-old vaccination in SPF chickens.
from specific pathogen free (SPF) chickens experimentally inoculated at day-old with one dose of rHVT-F vaccine over a 6-week period. Among the tested tissues, the rHVT-F vaccine was detected ...
Bluetongue surveillance system in Belgium: a stochastic evaluation of its risk-based approach effectiveness.
freedom of infection substantiation. Field data collected from the previous year’s outbreaks in Belgium were used to determine the risk groups to be considered. RESULTS: The best sensitivities at herd ...
Bovine tuberculosis surveillance alternatives in Belgium.
component was important. Using an antibody ELISA at purchase and an interferon gamma test during winter screening and at import would increase greatly the sensitivity and the confidence level of Belgium’s ...
Redesigning the serological surveillance program for notifiable avian influenza in Belgian professional poultry holdings.
study was aimed at redesigning the Belgian active surveillance program for domestic birds in professional poultry holdings based on a risk analysis approach. A stochastic quantitative analysis, combining ...
Identification of risk factors for the prevalence and persistence of Salmonella in Belgian broiler chicken flocks.
at the farm level to minimize cross-contamination from farm to fork. This paper seeks to answer two questions: (i) given the Salmonella status of the farm at a certain occasion (equal to the sampling ...
