Schmallenberg virus circulation in culicoides in Belgium in 2012: field validation of a real time RT-PCR approach to assess virus replication and dissemination in midges.
four different regions in Belgium between May and November 2012, were morphologically identified, age graded, pooled and tested for the presence of SBV RNA by realtime RT- PCR. The results demonstrate ...
The combination of attenuated Newcastle disease (ND) vaccine with rHVT-ND vaccine at 1 day old is more protective against ND virus challenge than when combined with inactivated ND vaccine.
would induce a long-lasting immunity, with no need for a booster vaccination at a later age. In this context, the duration of immunity delivered by a vaccination programme including a recombinant ...
Comparison of single 1-day-old chick vaccination using a Newcastle disease virus vector with a prime/boost vaccination scheme against a highly pathogenic avian influenza H5N1 challenge.
boost with an inactivated H5N9 vaccine (iH5N9). The heterologous prime/boost rNDV- H5 /iH5N9 combination afforded the best level of protection against the H5N1 challenge performed at 6 weeks of age. Two ...

Effect of a DIVA vaccine with and without in-feed use of coated calcium-butyrate on transmission of Salmonella Typhimurium in pigs.
experiment with 56 piglets (3-15 weeks of age): two groups were orally vaccinated with 107 — 108 Colony Forming Units (CFU)/2 mL of a new attenuated Salmonella Typhimurium vaccine ‘Salmoporc-∆rfaJ’ with DIVA ...
Setting up a SPF chicken model for the pathotyping of West Nile virus (WNV) strains.
that WNV strain virulence can be discriminated in a one-day-old SPF chicken model on the basis of mortality rates, while viremia and viral load in feathers appear to be age dependent rather than ...
Seroprevalence and potential risk factors for Brucella spp. infection in traditional cattle, sheep and goats reared in urban, periurban and rural areas of Niger.
0.9-1.8%) based on indirect ELISA test for Brucella antibodies. Animals aged of 1-4 years were found to be more susceptible than animals less than 1 year old (Odds ratio [OR] of 2.7; 95% CI: 1.43-5.28). For ...
Large-scale cross-sectional serological survey of Schmallenberg virus in Belgian cattle at the end of the first vector season.
conclusion that the Schmallenberg virus was widespread in Belgium during winter 2011. Seroprevalence was shown to be statistically associated to the animal’s age (P < 0.0001): with 64.9% (95% CI: ...
Serological and virological BVDV prevalence and risk factor analysis for herds to be BVDV seropositive in Belgian cattle herds.
Belgium, a cross-sectional study was performed between November 2009 and March 2010. Young stock aged between 6 and 12 months from 773 randomly selected Belgian cattle herds were tested for BVDV-specific ...
