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

Correlation Coefficient of 0.3 (P < 0.001) was found, indicating that the correlation between two animals within a herd with respect to their serological status was high. Those results corroborate the ...

Electron tomography of negatively stained complex viruses: application in their diagnosis.

of representative examples of parapoxviruses and paramyxoviruses was combined with electron tomographic analysis. RESULTS: Digital sectioning of reconstructions of these viruses at a selected height ...

Application of a Commercial Real-Time RT-PCR Assay for Surveillance of Classical Swine Fever: Evaluation by Testing Sequential Tissue and Blood Samples

to compensate the lower viral load observed in blood. Based on these results, testing of blood can be proposed as an acceptable alternative to tonsils for herd surveillance with the TaqVet CSF kit, ...

Monitoring of pigeon paramyxovirus type-1 in organs of pigeons naturally infected with Salmonella Typhimurium.

organs of inoculated or contact pigeons naturally infected with Salmonella Typhimurium. With two exceptions, both groups presented similar results. Typical nervous signs and a green diarrhoea were ...

Development of immunocompetence of broiler chickens.

of age. These findings indicate that vaccination at 1 day of age does not activate the B-cell response resulting in antibody production and support the idea that the immune function of the late ...

High-level expression of Chlamydia psittaci major outer membrane protein in COS cells and in skeletal muscles of turkeys.

the cytoplasm of transfected COS7 cells as well as in the plasma membrane and was immunoaccessible. Intramuscular administration of pcDNA1/ MOMP in specific-pathogen-free turkeys resulted in local ...

Comparative Analysis of Different Serological and Molecular Tests for the Detection of Small Ruminant Lentiviruses (SRLVs) in Belgian Sheep and Goats.

infection before seroconversion at two weeks post infection and showed a specificity of 100%. Sensitivity however remained suboptimal at 85%. These results allow to propose a faster and cheaper diagnostic ...

(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 ...

Transmission of Bluetongue Virus Serotype 8 by Artificial Insemination with Frozen-Thawed Semen from Naturally Infected Bulls.

and this had a significant impact on the infection rate, the time of onset of viraemia post artificial insemination, and the gestational stage at which pregnancy loss occurred. These results, which ...

Development and evaluation of a core genome multilocus sequence typing scheme for Paenibacillus larvae, the deadly American foulbrood pathogen of honeybees.

a country-wide beekeeping operation. cgMLST greatly enhances the power of a traditional typing scheme, while preserving the same stability and standardization for sharing results and methods across ...
