Evaluation of two different swab transport systems in the detection of avian influenza virus excretion from infected Pekin ducks (Anas platyrhynchos).
infection status of individual birds was correctly determined. Health Topics: Animal health Category: A1 FOS Classification: 4.03 Veterinary science ...
Emergence of bluetongue serotypes in Europe, part 1: description and validation of four real-time RT-PCR assays for the serotyping of bluetongue viruses BTV-1, BTV-6, BTV-8 and BTV-11.
of bluetongue virus (BTV) in Central-Western Europe is greatly complicated by the coexistence of several BTV serotypes. Rapid, sensitive and specific assays are therefore needed to correctly identify ...
Expert judgement in a risk assessment model for Salmonella spp. in pork: the performance of different weighting schemes.
the uncertainty on the model input parameters. The performance of experts as probability assessors was measured by the experts’ ability to correctly and precisely provide estimates for a set of seed ...
The importance of quality assurance/quality control of diagnostics to increase the confidence in global foot-and-mouth disease control.
diagnostic tests fully and to install a continuous quality control (QC) monitoring system. Knowledge of performance characteristics of diagnostics is essential to interpret results correctly and to calculate ...
Classification of sporadic Creutzfeldt-Jakob disease based on clinical and neuropathological characteristics.
neuropathological investigation. We focus on the classification of neuropathologically confirmed sCJD patients. In order to obtain a classification rule that correctly classifies this type of patients and at the same ...
Evaluation of amplified rDNA restriction analysis (ARDRA) for the identification of Mycoplasma species.
mycoides cluster, for which correct ARDRA profiles were only obtained if the sequences of both rrn operons were taken into account. CONCLUSION: Theoretically, restriction digestion of the amplified rDNA was ...
Real-time PCR for simultaneous detection and genotyping of bovine viral diarrhea virus.
coefficients of variation of threshold cycle values in inter-runs were less than 2.2%. The correct classification of genotype I and II viruses was assessed by using reference strains and characterized field ...
An experimental infection with a classical swine fever virus in weaner pigs. II. The use of serological data to estimate the day of virus introduction in natural outbreaks.
model was applied to seroprevalence data from three outbreaks of the 1993-1994 epizootic to test whether the model could predict correctly the day of virus introduction into the herd. It was concluded ...
Comparative Analysis of Different Serological and Molecular Tests for the Detection of Small Ruminant Lentiviruses (SRLVs) in Belgian Sheep and Goats.
assays (ELISA s) (Elitest and ID screen kits) showed the highest sensitivities (>96%) and specificities (>95%) in both species, and their combined use allowed to correctly identify the infection ...
