Publication Type: Peer reviewed scientific article Authors: Goris, N; Kris De Clercq Source: Rev Sci Tech, Volume 24, Issue 3, p.1005-16 (2005) Keywords: Animals Antibodies, Viral Cattle Clinical Laboratory Techniques Commerce Enzyme-Linked Immunosorbent ...
Detection of BVDV persistently infected animals in Belgium: evaluation of the strategy implemented.
part of the country. The strategy of detection of PI animals relies on PCR testing of pools of blood. Individual blood samples corresponding to the positive pools are then tested by BVDV-antigen ELISA. ...
First results of chronic wasting disease (CWD) surveillance in the south-eastern part of Belgium.
Rocky mountain elk and white-tailed deer in the area of Colorado, Wyoming, and Nebraska, and new foci of CWD have been detected in other parts of the United States. However, no large-scale active ...
The occurrence of encephalomyocarditis virus (EMCV) in European pigs from 1990 to 2001.
outbreaks were analysed and serum samples, partly from existing screening programmes, were tested for antibodies against EMCV. Most clinical EMCV outbreaks were reported in Belgium (320), followed by Italy ...
Quasispecies nature of an unusual avian paramyxovirus type-1 isolated from pigeons.
isolated from sick, unvaccinated pigeons, it was not grouped with pigeon variants regarding its antigenic and genetic characterisation. We analysed its quasispecies nature by cloning and sequencing parts of ...
Risk analysis of the spread of classical swine fever virus through "neighbourhood infections" for different regions in Belgium.
a second part of the study, the likelihood for the occurrence of neighbourhood infections within an area with a 1 km radius was predicted for every Belgian pig herd, assuming that the herd was infected with ...
Molecular characterisation of three avian paramyxovirus type 1 isolated from pigeons in France.
type 1 (aPMV-1) isolated from pigeons duringpigeon paramyxovirosis outbreaks were molecularly characterised by sequencing parts of the six genes (NP, P, M, F, HN and L) of each strain. Virulent 99143 ...
Monitoring of pigeon paramyxovirus type-1 in organs of pigeons naturally infected with Salmonella Typhimurium.
samples remained positive during most of the experiment, seemed to be the principal targets for virus persistence. However, the virus was significantly recovered later in the brain parts and for longer in ...
Cloning and sequencing of wsp encoding gene fragments reveals a diversity of co-infecting Wolbachia strains in Acromyrmex leafcutter ants.
Bacterial Outer Membrane Proteins Cloning, Molecular Phylogeny Sequence Analysis, DNA Wolbachia Abstract: By sequencing part of the wsp gene of a series of clones, we detected an unusually high diversity of ...
Dynamics of immune cell infiltration in the caecal lamina propria of chickens after neonatal infection with a Salmonella enteritidis strain.
came somewhat later, subsequently organising into follicular aggregates. An early increase in granulocytes was partly masked by the response to natural flora. While the B-lymphocyte and granulocyte ...
