Evaluation of 16 commercial antibody ELISAs for the detection of bovine viral diarrhea virus-specific antibodies in serum and milk using well-characterized sample panels.
analytical sensitivity (DS e and AS e, respectively), diagnostic specificity (DS p), and repeatability relative to the virus neutralization (VN) test considered to be the gold standard assay. Using serum as ...
Serological diagnosis of bovine neosporosis: a Bayesian evaluation of two antibody ELISA tests for in vivo diagnosis in purchased and abortion cattle.
currently used in Belgium for bovine sera (TEST A and TEST B). The goal of this study is to evaluate these tests used at their current cut-offs, with a no gold standard approach, for the test purpose of (1) ...
Autochthonous tick-borne encephalitis virus-seropositive cattle in Belgium: a risk-based targeted serological survey.
screening was performed on Belgian cattle (n=650), selected from the 2010 Belgian national cattle surveillance serum bank. All samples were subjected to a gold standard TBEV seroneutralization test (SNT), ...
Comparative evaluation of live marker vaccine candidates "CP7_E2alf" and "flc11" along with C-strain "Riems" after oral vaccination.
assessments were done in comparison with the conventional “gold standard” C-strain “Riems” vaccine. In addition to the challenge trials, multiple vaccinations with both candidates were performed to further ...
Methodologies for Salmonella enterica subsp. enterica subtyping: gold standards and alternatives.
Publication Type: Peer reviewed scientific article Authors: P Wattiau; Cécile Boland; Sophie Bertrand Source: Appl Environ Microbiol, Volume 77, Issue 22, p.7877-85 (2011) Keywords: Animals Bacterial Typing Techniques Epidemiologic Methods Humans Salmonel ...
A Bayesian evaluation of six diagnostic tests for foot-and-mouth disease for vaccinated and non-vaccinated cattle.
unknown, a Bayesian analysis employing a latent class model was used that did not rely on the use of a reference test or gold standard. Prior information about prevalence for subsets of the data and ...
Foot-and-mouth disease vaccine potency testing in cattle using homologous and heterologous challenge strains: precision of the "Protection against Podal Generalisation" test.
relatedness of the vaccine strain and circulating field isolate. The “Gold Standard” FMD vaccine potency test is the in vivo test performed in the target species. The objective of the study was to determine the ...
Estimating the probability of freedom of classical swine fever virus of the East-Belgium wild-boar population.
estimation, accounting for the diagnostic test characteristics without the assumption of the presence of a gold standard. The median probability of freedom of CSF-virus was estimated at 0.970, with a 95% ...
Reduction of singleton reactors against swine vesicular disease virus by a combination of virus neutralisation test, monoclonal antibody-based competitive ELISA and isotype specific ELISA.
trade. For the virus neutralisation test, the gold standard for SVD, singleton reactors are found at a level of 1-3/1000. Singleton reactors also occur when other serological testing methods are used. The ...
