Evaluation of an interferon-gamma release assay for early detection of lumpy skin disease virus infection and vaccination in cattle.
a specificity of up to 100%. The LSD IGRA could be a powerful immunoassay for early detection of LSD and post-vaccination monitoring, making it worthwhile to explore its diagnostic characteristics in more animals ...
Allele Frequencies of Genetic Variants Associated with Varroa Drone Brood Resistance (DBR) in Apis mellifera Subspecies across the European Continent.
that variant type allele frequencies of these variants are primarily related to the subspecies or phylogenetic honey bee lineage. Our results confirm that population-specific genetic markers should ...
PRRSV-Vaccinated, Seronegative Sows and Maternally Derived Antibodies (I): Impact on PRRSV-1 Challenge Outcomes in Piglets.
PRRSV-seropositive sows (responders to vaccination) and had a clear presence of PRRSV-specific MDA s (E+ piglets). The other eighteen piglets were born from three PRRSV-seronegative sows (non-responders to ...
Follow-Up of PRRSv-Vaccinated Piglets Born from PRRSv-Vaccinated, ELISA-Seropositive and ELISA-Seronegative Sows.
presence of PRRS v-specific maternally-derived antibodies (MDA s) and the PRRS v vaccine response in both groups of piglets. The E- piglets lacked the presence of PRRS v-specific MDA s (0% seropositive), ...
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.
phenomenon (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 ...
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.
Laboratories in Europe participated in the study and analysed 12 samples with adult coleopterans and insect larvae. The performance of the laboratories was evaluated in terms of sensitivity and specificity ...
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 ...
