to susceptible animals, regardless of the floor system. This study shows that environmental factors such as floor systems used in poultry barns may act upon the transmission of LPAIV s. However, the ...
Bluetongue surveillance system in Belgium: a stochastic evaluation of its risk-based approach effectiveness.
passive clinical surveillance, export testing. Scenario tree methodology was used to evaluate the relative sensitivity of detection and targeted approach of each component in terms of early detection and ...
A dynamic spatio-temporal model to investigate the effect of cattle movements on the spread of bluetongue BTV-8 in Belgium.
Northern Europe. Using information on the 2006 Bluetongue outbreak in cattle farms in Belgium, a spatio-temporal transmission model was formulated. The model quantifies the local transmission of the disease ...
Bovine tuberculosis surveillance alternatives in Belgium.
36,059 cattle herds still active in 2009. The current surveillance program sensitivity as well as the impact of alternative surveillance protocols was simulated in a stochastic model using 10,000 ...

in humans. Phage typing was confirmed to be a useful tool for identifying temporal trends. Health Topics: Cabine de bronzage Category: A1 FOS Classification: 3.02 Clinical medicine ...
Redesigning the serological surveillance program for notifiable avian influenza in Belgian professional poultry holdings.
estimated on the basis of the different sensitivities obtained. This study proved to be a useful tool for decision makers, providing insight on how to reallocate the total amount of samples to be taken in the ...
Identification of risk factors for the prevalence and persistence of Salmonella in Belgian broiler chicken flocks.
consecutive flocks? We used surveillance data on 6824 broiler flocks studied for Salmonella infectivity from 2005 to 2006 in Belgium. The farms were tested regularly (3 weeks before slaughter of each broiler ...
