Prevalence of Mycoplasma gallisepticum and Mycoplasma synoviae in commercial poultry, racing pigeons and wild birds in Belgium.
a high prevalence was found in broilers (12.9%: 95% CI: 11.1-14.9%). Four samples collected by hunters gave a positive result for M. synoviae (4%: 95% CI: 1.6-9.8%): one carrion crow and three wood ...
Application of syndromic surveillance on routinely collected cattle reproduction and milk production data for the early detection of outbreaks of Bluetongue and Schmallenberg viruses.
the sensitivity and timeliness of these methods. The methods investigated in this study did not result in a more timely detection of BTV-8 and SBV in the Netherlands and BTV-8 in Belgium given the ...
Exploring cattle movements in Belgium.
Walloon regions could result in a spread toward the East and West Flanders regions, as what happened in the case of Bluetongue BTV-8 outbreak in 2006. The temporal component in the model also revealed ...
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 ...
A dynamic spatio-temporal model to investigate the effect of cattle movements on the spread of bluetongue BTV-8 in Belgium.
between farms within a municipality, the short-distance transmission between farms across neighbouring municipalities and the transmission as a result of cattle movement. Different municipality-level ...

Salmonella Infections Salmonella Infections, Animal Seasons Abstract: OBJECTIVES: The aim of this study was to investigate the available results for Belgium of the European Union coordinated monitoring program ...
Further evidence of antigenic drift and protective efficacy afforded by a recombinant HVT-H5 vaccine against challenge with two antigenically divergent Egyptian clade 2.2.1 HPAI H5N1 strains.
(rHVT- H5) and a Mexican-origin H5N2 inactivated vaccine, alone or in combination, against two antigenically divergent H5N1 Egyptian strains isolated in 2007 and 2008. Our results confirm the existence of ...
Identification of risk factors for the prevalence and persistence of Salmonella in Belgian broiler chicken flocks.
random-intercept logistic regression models were employed to analyse these correlated binary data. Our results indicated that there are many factors that influence Salmonella risk in broiler flocks, and that they ...
