Estimation of seroprevalence of encephalomyocarditis in Dutch sow herds using the virus neutralization test.
to estimate the seroprevalence of EMCV infection in Dutch sow herds. A total of 277 Dutch sow herds were randomly selected, from which 3237 serum samples were collected. These samples were tested for ...
Estimating the probability of freedom of classical swine fever virus of the East-Belgium wild-boar population.
in Belgium in 1998. In our study, the probability of freedom of CSF-virus was estimated based on 789 samples; these were collected from wild-boars within the surveillance programme (within the three ...
First results of chronic wasting disease (CWD) surveillance in the south-eastern part of Belgium.
12F10. There were no indications on the occurrence of transmissible spongiform enncephalopathy (TSE) in any of the samples. A Bayesian framework was used for the estimation of the true prevalence of CWD in ...
Differential inequity in health expectancy by region in Belgium.
(5-years follow-up of the 1991 census) are combined with the 1997 Health Interview Survey to estimate the DFLE by education. Differences in partial life expectancy25-74 (LE25-74) and in DFLE25-74 between ...
Quality of care assessment using GPs' electronic patient records: do we need data from home visits?
estimate of the quality of care, whereas conclusions on quality improvement remain relatively stable. Quality of care assessment with the EPR of GP s seems not to be dramatically hampered by the poor ...
Protein growth rate in rainbow trout (Oncorhynchus mykiss) is negatively correlated to liver 20S proteasome activity.
We selected fish for high and low growth efficiencies. Protein degradation was estimated from the difference between protein synthesis (determined by 15N flux) and protein growth. We found that protein ...
Carbon source-induced modifications in the mycolic acid content and cell wall permeability of Rhodococcus erythropolis E1.
estimated by high-performance liquid chromatography and mass spectrometry. Two types of mycolic acid patterns were observed after growth either on saturated linear alkanes or on short-chain alkanoates. One ...
Characterisation of reversed-phase liquid chromatographic columns by chromatographic tests. Rational column classification by a minimal number of column test parameters
conducted using 24 parameters that could be measured in a repeatable and reproducible way. Principal component analysis was used to classify the columns and to estimate the minimal number of parameters ...

Risk analysis of the spread of classical swine fever virus through "neighbourhood infections" for different regions in Belgium.
occurred in the East Flanders Province of Belgium in 1994. The only risk factor that was associated with the occurrence of “neighbourhood infections” was a kernel estimation of the intensity of neighbouring ...
