Bayesian estimation of the true prevalence, sensitivity and specificity of the Rose Bengal and indirect ELISA tests in the diagnosis of bovine brucellosis.
performance and discriminative ability. The objective of this study was to assess the performance of the Rose Bengal test (RBT) and an indirect ELISA (iELISA) in diagnosing brucellosis in 995 serum samples ...
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.
passive immunity to both the vector (HVT) and the insert (H5) and is consequently applicable at the hatchery. The objectives of this trial were to evaluate the impact of maternally derived antibodies (MDA ...
Potency of a recombinant NDV-H5 vaccine against various HPAI H5N1 virus challenges in SPF chickens.
viruses. Obtained protections were dependent on the age of the chickens, on the constructs and, in particular, on the homology between the HA that was inserted and the challenge strains. The objective of ...
Assessment of the long-term effect of vaccination on transmission of infectious bovine rhinotracheitis virus in cattle herds hyperimmunized with glycoprotein E-deleted marker vaccine.
Vaccines, Inactivated Viral Proteins Viral Vaccines Abstract: OBJECTIVE: To assess long-term effects and risk factors for the efficacy of hyperimmunization protocols against infectious bovine rhinotracheitis ...
Heterozygous inactivation of the Na/Ca exchanger increases glucose-induced insulin release, β-cell proliferation, and mass.
Transplantation Male mice Sodium-Calcium Exchanger Abstract: OBJECTIVE: We have previously shown that overexpression of the Na-Ca exchanger (NCX1), a protein responsible for Ca(2+) extrusion from cells, increases ...
Aggregate size and architecture determine microbial activity balance for one-stage partial nitritation and anammox.
A, B, and C, were used. The test objectives were (i) to quantify the AerAOB and AnAOB abundance and the activity balance for the different aggregate sizes and (ii) to relate aggregate morphology, size ...
NUSAP method for evaluating the data quality in a quantitative microbial risk assessment model for Salmonella in the pork production chain.
in the QMRA model. The NUSAP methodology and kite diagrams are objective tools to discuss and visualize the quality of the parameters in a structured way. These two tools can be used in the selection ...
Bluetongue in Belgium: episode II.
8 (BTV-8). The first BTV-8-case of the year 2007 in Belgium was notified in July. This case was the starting point of a second wave of BT outbreaks. The main objective of this study was to describe the ...
Establishing the spread of bluetongue virus at the end of the 2006 epidemic in Belgium.
of herds with confirmed clinical infected ruminants. A cross-sectional serological survey targeting all Belgian ruminants was then undertaken during the vector-free season. The first objective of this ...
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 ...
