Development and Validation of a New DIVA Real-Time PCR Allowing to Differentiate Wild-Type Lumpy Skin Disease Virus Strains, Including the Asian Recombinant Strains, from Neethling-Based Vaccine Strains.
confirmed on samples from LSDV infected and vaccinated animals and on isolates of LSDV recombinants (n = 12), vaccine (n = 5), and classic wild-type strains (n = 6). No cross-reactivity or a-specificity with ...
Tick-Borne Encephalitis Virus Prevalence in Sheep, Wild Boar and Ticks in Belgium.
antibodies by ELISA and plaque reduction neutralization test (PRNT), respectively. The specificity of positive samples was assessed by PRNT s for TBEV and the Louping Ill, West Nile, and Usutu viruses. TBEV ...
Porcine Reproductive and Respiratory Syndrome virus (PRRSv): A Cross-Sectional Study on ELISA Seronegative, Multivaccinated Sows
(prevalence–origin–consequences) was not yet investigated. In this study, the prevalence of ELISA non-responders was assessed by measuring PRRS v-specific antibodies in 1400 sows, originating from 70 PRRS v-vaccinating sow herds, ...

The history of foot-and-mouth disease virus serotype C: the first known extinct serotype?Abstract
of this serotype, as unequivocal interpretation is hampered by incomplete intra-serotype specificity of immunoassays and the continued use of this serotype in vaccines. It is recommended to continue ...
Reliability of Morphological and PCR Methods for the Official Diagnosis of Aethina tumida (Coleoptera: Nitidulidae): A European Inter-Laboratory Comparison.

Species-Specific Humoral Immune Responses in Sheep and Goats upon Small Ruminant Lentivirus Infections Inversely Correlate with Protection against Virus Replication and Pathological Lesions.
Sheep Sheep Species Specificity Viral Load Virus Replication Visna-maedi virus Abstract: Maedi-Visna-like genotype A strains and Caprine arthritis encephaltis-like genotype B strains are small ruminant ...
Selection and use of reference panels: a case study highlighting current gaps in the materials available for foot and mouth disease.
comparative purposes and the calibration of test results across different laboratories. Using foot and mouth disease (FMD) as an example, this review highlights four specific areas where new reference reagents ...
Review: Vaccines and Vaccination against Lumpy Skin Disease
places specific demands on the tools and methods used to evaluate the effectiveness of the LSD vaccination campaigns in the field. We aimed to give a comprehensive update on available vaccines and ...
Selection and use of reference panels: a case study highlighting current gaps in the materials available for foot and mouth disease
an example, this review highlights four specific areas where new reference reagents are required. These are to: reduce bias in estimates of the diagnostic sensitivity and inter-serotypic specificity of ...
