Large-scale cross-sectional serological survey of Schmallenberg virus in Belgian cattle at the end of the first vector season.
after the first period of infection of the emerging Schmallenberg virus. A total number of 11 635 cattle from 422 herds sampled between 2 January and 7 March 2012 were tested for the presence of ...
Efficacy of rHVT-AI vector vaccine in broilers with passive immunity against challenge with two antigenically divergent Egyptian clade 2.2.1 HPAI H5N1 strains.
thousands of chicks from 7 to 10 days old on farms has been determined to be unreliable and, therefore, poorly efficacious. For these reasons, interest has arisen regarding a newly developed live recombinant ...
Potency of a recombinant NDV-H5 vaccine against various HPAI H5N1 virus challenges in SPF chickens.
(rNDV) have been used as a vector to express native or modified avian influenza (AI) hemagglutinins (HA) in order to give preventive protection against highly pathogenic avian influenza (HPAI) H5N1 ...
Immune responses and protection against H5N1 highly pathogenic avian influenza virus induced by the Newcastle disease virus H5 vaccine in ducks.
a Newcastle disease virus (NDV) vector expressing an H5N1 hemagglutinin (rNDV- H5) were investigated in mule ducks, a hybrid between Muscovy (Cairina moschata domesticus) males and Pekin (Anas platyrhynchos ...
Impact of a novel inactivated PRRS virus vaccine on virus replication and virus-induced pathology in fetal implantation sites and fetuses upon challenge.
control of porcine reproductive and respiratory syndrome (PRRS). Recently, in our laboratory, an inactivated porcine reproductive and respiratory syndrome virus (PRRSV) vaccine has been developed. Promising ...
Efficacy of marker vaccine candidate CP7_E2alf in piglets with maternally derived C-strain antibodies.
with pigs. Therefore, new generations of promising marker vaccines have been developed, among them the chimeric vaccine CP7_E2alf. However, in populations previously vaccinated with live attenuated ...
Bluetongue sentinel surveillance program and cross-sectional serological survey in cattle in Belgium in 2010-2011.
BTV-8 with inactivated vaccines was initiated in Belgium in spring 2008 and appeared to be successful. Since 2009, no clinical cases of Bluetongue (BT) have been reported in Belgium and BTV-8 circulation ...
Evaluation of two different swab transport systems in the detection of avian influenza virus excretion from infected Pekin ducks (Anas platyrhynchos).
role of wild birds in the epidemiology and ecology of influenza A viruses has long been recognised (Alexander, 2007a). As a result of the emergence of a H5N1 highly pathogenic avian influenza (HPAI) ...
Characteristics of serology-based vaccine potency models for foot-and-mouth disease virus.
of animals each year. Despite considerable efforts during the past decades, a challenge-free alternative vaccine potency test to replace the European protective dose 50% test (PD (50)) has not been ...
B. anthracis in a wool-processing factory: seroprevalence and occupational risk.
Abstract: In a Belgian wool-processing factory, living anthrax spores were found in raw goat hair and air dust, but confirmed anthrax cases had never been reported. Anthrax vaccines are not licensed nor ...
