Retrospective survey of unauthorized genetically modified bacteria harbouring antimicrobial resistance genes in feed additive vitamin B2 commercialized in Belgium: Challenges and solutions
allowing to provide a first picture of GM bacterial contaminations. It consisted in a first-line screening strategy gathering available PCR-based methods targeting both the B. subtilis species, frequently ...
Evaluation of three competitive ELISAs and a fluorescence polarisation assay for the diagnosis of bovine brucellosis.
adult cattle were tested. Individual test sensitivities (Se) and specificities (Sp) were estimated. Threshold assessment using the receiver operating characteristic method was also performed. The most ...
Multiyear Serological Surveillance of Notifiable Influenza A Viruses in Belgian Poultry: A Retrospective Analysis.
ELISA has been used as first screening method since 2010. A retrospective analysis of the serological monitoring performed from 2007 through 2013 showed sporadic circulation of notifiable ...
Serologic screening for 13 infectious agents in roe deer (Capreolus capreolus) in Flanders.
we conducted a serologic screening in 12 hunting areas. MATERIALS AND METHODS: Roe deer sera collected between 2008 and 2013 (n=190) were examined for antibodies against 13 infectious agents, using ...
Identification and complete genome sequencing of paramyxoviruses in mallard ducks (Anas platyrhynchos) using random access amplification and next generation sequencing technologies.
BACKGROUND: During a wildlife screening program for avian influenza A viruses (AIV) and avian paramyxoviruses (APMV) in Belgium, we isolated two hemagglutinating agents from pools of cloacal swabs of wild ...
Deoxynivalenol loads in matched pair wheat samples in Belgium: comparison of ELISA VERATOX kit against liquid chromatography.
VERATOX kits are valuable for quantitative screening and even for an initial exposure assessment in situations when there are practical or economical reasons not to use sophisticated methods such as HPLC or ...
Diagnostic performance and application of two commercial cell viability assays in foot-and-mouth disease research.
Publication Type: Peer reviewed scientific article Authors: Willems, Tom; David Lefebvre; Neyts, Johan; Kris De Clercq Source: J Virol Methods, Volume 173, Issue 1, p.108-14 (2011) Keywords: Animals ...
Evaluation of different strategies for the use of ELISA tests as first screening tools for serologic surveillance of low pathogenic avian influenza in the Belgian poultry sector.
detection of H5 and H7 subtypes. However, as the number of tested sera has been increasing, there is a need for another serologic method that could be used as a preliminary screening test. A comparison of ...
Microscopic and molecular studies of the diversity of free-living protozoa in meat-cutting plants.
sequencing of PCR-amplified, denaturing gradient gel electrophoresis (DGGE)-separated 18S rRNA gene fragments, which was used as a fast screening method. The general results of the survey showed that ...
Comparative evaluation of six ELISAs for the detection of antibodies to the non-structural proteins of foot-and-mouth disease virus.
sensitivity, but not necessarily for specificity. A commercial kit from Cedi-diagnostics and an in-house assay from IZS-Brescia were comparable to the NCP anaftosa-screening index method described in the ...
