Large-scale cross-sectional serological survey of Schmallenberg virus in Belgian cattle at the end of the first vector season.

conclusion that the Schmallenberg virus was widespread in Belgium during winter 2011. Seroprevalence was shown to be statistically associated to the animal’s age (P < 0.0001): with 64.9% (95% CI: ...

Evaluation of four enzyme-linked immunosorbent assays for the serologic survey of avian influenza in wild bird species.

tests for validation purposes. Cohen’s kappa statistics and Spearman correlation coefficients were calculated for each combination of two tests and for each bird species. Test agreement for mallard sera ...

Characteristics of serology-based vaccine potency models for foot-and-mouth disease virus.

Neutralization Tests Predictive Value of Tests Reproducibility of Results Roc Curve Statistics as Topic Viral Vaccines Abstract: BACKGROUND: Foot-and-mouth disease (FMD) vaccine potency testing involves hundreds ...

Quantitative characterization of agglomerates and aggregates of pyrogenic and precipitated amorphous silica nanomaterials by transmission electron microscopy.

particles. This reduces operator-induced bias and assures a statistically relevant number of measurements, avoiding the tedious repetitive task of manual measurements. Access to multiple parameters further ...

Indirect foot-and-mouth disease vaccine potency testing based on a serological alternative.

Foot-and-mouth disease vaccine potency testing in cattle using homologous and heterologous challenge strains: precision of the "Protection against Podal Generalisation" test.

animals should be used in order to increase the test’s statistical power. In this regard, indirect alternative tests for vaccine potency and vaccine matching merit consideration. Health Topics:  Animal ...

Use of continuous results to compare ELISAs for the detection of antibodies to non-structural proteins of foot-and-mouth disease virus.

Association of myocarditis with high viral load of porcine circovirus type 2 in several tissues in cases of fetal death and high mortality in piglets. A case study.

without myocarditis (N = 14) (average age 20.0 days), and control animals from a different herd (N = 5) (newborn). Statistically significant differences were observed in the mean porcine circovirus 2 (PCV2) ...

Classification of sporadic Creutzfeldt-Jakob disease based on clinical and neuropathological characteristics.

examination reveals cortical spongiform change, hence the term ‘spongiform encephalopathy’. Several statistical techniques were applied to classify patients with sporadic CJD (sCJD), based on clinical and ...
