A serological survey to detect Schmallenberg virus (SBV)-specific antibodies by ELISA was organized in the Belgian sheep population to study the seroprevalence at the end of the epidemic. One thousand eighty-two sheep samples which were collected from 83 herds all over Belgium between November 2011 and April 2012 were tested. The overall within-herd… (More)
In 2011, a novel Orthobunyavirus was identified in cattle and sheep in Germany and The Netherlands. This virus was named Schmallenberg virus (SBV). Later, presence of the virus was confirmed using real time RT-PCR in cases of congenital malformations of bovines and ovines in several European countries, including Belgium. In the absence of specific… (More)
Bovine viral diarrhoea virus (BVDV) is a worldwide spread virus that most commonly infects cattle and can cause considerable economic losses. To determine the prevalence of BVDV in 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… (More)
Preventing congenital infection is important for the 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 results in young pigs encouraged us to test the vaccine potency to prevent congenital infection. In… (More)
In an attempt to produce Hog Cholera virus (HCV) preparations of high titre, optimal growth and trypsinization conditions of PK-15 microcarrier cell cultures were defined. Infecting a PK-15 Cytodex 3® microcarrier culture with HCV increased the yield of virus more than 10 times compared with conventional monolayer culture in Roux flasks.
A panel of 15 monoclonal antibodies (Mabs) against hog cholera virus (HCV) was produced and each Mab was characterized according to its viral protein specificity, virus-neutralizing activity and immunoreactivity with a large collection of HCV isolates.
A panel of 15 monoclonal antibodies, produced against the hog cholera virus, were characterized by radioimmunoprecipitation assays. Using this panel, we were able to identify 4 sets of monoclonal antibodies precipitating each a different viral protein with relative molecular weight of 40, 46, 120 kDa, respectively, and a protein complex containing 15, 16,… (More)
A cross-sectional survey was conducted in the Belgian cattle population 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 Schmallenberg-specific antibodies using an ELISA kit. Between-herd seroprevalence in cattle… (More)
Tick-borne encephalitis virus (TBEV) is an important emerging tick-borne viral infection of humans and dogs in Europe. Currently, TBEV surveillance is virtually nonexistent in Belgium, which is considered nonendemic. A commercial enzyme-linked immunosorbent assay (ELISA) was adapted for the detection of TBEV-specific IgG-antibodies in canine sera. Serum… (More)
After amplification by PCR, the 5′ region of the genome of hog cholera virus (HCV) strain Alfort 187 was cloned and sequenced. The nucleotide and deduced amino acid sequences were compared with the ones of other pestiviruses. By in vitro translation experiments we were able to demonstrate the protease activity of the p 20 protein of HCV.
