Unraveling clonal CD8 T cell expansion and identification of essential factors in γ-herpesvirus-induced lymphomagenesis.
or SH3 motifs (or both) were able to induce MCF, a recombinant virus expressing a mutated form of A10 unable to phosphorylate its tyrosine residues resulted in the lack of MCF and protected against ...
PRRSV-Vaccinated, Seronegative Sows and Maternally Derived Antibodies (II): Impact on PRRSV-1 Vaccine Effectiveness and Challenge Outcomes in Piglets.
Syndrome virus (PRRSV) is widely practiced in both sows and piglets. However, it has been shown that multivaccinated sows sometimes lack a detectable antibody response, testing seronegative in ELISA ...
PRRSV-Vaccinated, Seronegative Sows and Maternally Derived Antibodies (I): Impact on PRRSV-1 Challenge Outcomes in Piglets.
lacking PRRSV-specific MDA s might pose a risk for PRRSV infection and enhanced transmission in pig farms in young piglets. Health Topics: Santé animale Animal health Diergezondheid Service: Viral ...
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.
lacking, and no studies have assessed its seroprevalence in sheep. Serum samples of 480 sheep from all over Belgium and 831 wild boar hunted in Flanders (northern Belgium) were therefore screened for TBEV ...
Seroprevalence and risk factors related to small ruminant lentivirus infections in Belgian sheep and goats.
however exists, but less than 2% of the farmers participate to the program. The current lack of SRLV seroprevalence data and knowledge on risk factors related to SRLV seropositivity in this hobbyist sector ...
Evaluation of the kinetics of anti-NP and anti-HA antibody after infection of Pekin ducks with low pathogenic avian influenza virus
Dissimilar kinetics of the antibodies detected during the follow-up evaluation of the humoral immune responses in experimentally infected ducks may explain this lack of correlation. Indeed, anti- NP titres ...
Comparative Analysis of Different Serological and Molecular Tests for the Detection of Small Ruminant Lentiviruses (SRLVs) in Belgian Sheep and Goats.
status of all animals. Individual agar gel immunodiffusion (AGID s) kits lacked sensitivity, but interestingly, the combined use of both kits had a sensitivity and specificity of 100%. qPCRs detected SRLV ...
(Non-)Sense of Milk Testing in Small Ruminant Lentivirus Control Programs in Goats. Comparative Analysis of Antibody Detection and Molecular Diagnosis in Blood and Milk.
with a 10-fold higher analytical sensitivity of the ID screen test. In contrast to the overall good ELISA results, qPCR on milk cell pellets lacked sensitivity (81%) and specificity (88%), compared to ...
