Epidemiological study of bovine norovirus infection by RT-PCR and a VLP-based antibody ELISA.
diarrhoeic calves screened by RT- PCR. Nucleotide sequencing performed on the polymerase region classified all the norovirus amplicons in the bovine norovirus genotype 2. Rather surprisingly, some rotavirus ...
Vaccination of birds other than chickens and turkeys against avian influenza.
of serological data. Whenever experimental challenge was performed in birds other than chickens and turkeys, vaccination using inactivated vaccines always protected against disease and mortality, ...
The major portal of entry of koi herpesvirus in Cyprinus carpio is the skin.
further demonstrate the role of the skin as the KHV portal of entry, we constructed an original system, nicknamed “U-tube,” to perform percutaneous infection restricted to the posterior part of the fish. ...
Technical note: Flow cytometric identification of bovine milk neutrophils and simultaneous quantification of their viability.
iodide was used to determine milk PMNL viability. Thirty milk samples were run in parallel to assess the repeatability of the immunoassay and 6 repeated measurements per sample were performed to assess the ...
Some guidelines for determining foot-and-mouth disease vaccine strain matching by serology.
of foot-and-mouth disease (FMD) virus can be assessed in vivo or by serological r-value determination. Sera from animals involved in vaccine potency and cross-protection trials performed using the ...
Comparison of classical serotyping and PremiTest assay for routine identification of common Salmonella enterica serovars.
Salmonella kit uses a multiplexed DNA typing test aimed at identifying common serovars of Salmonella enterica. It was used in assays over a 9-month period in the Belgian reference laboratory that performs the ...
Vaccination of calves using the BRSV nucleocapsid protein in a DNA prime-protein boost strategy stimulates cell-mediated immunity and protects the lungs against BRSV replication and pathology.
in cattle. This was performed according to a DNA prime-protein boost strategy. The results showed that DNA vaccination primed a specific T-cell-mediated response, as indicated by both ...
Indirect foot-and-mouth disease vaccine potency testing based on a serological alternative.
(FMD) vaccine potency testing has historically been performed by experimentally infecting vaccinated cattle. A few alternative approaches to the in vivo challenge test based on the correlation between ...
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 ...
Occurrence and genetic diversity of Bacillus anthracis strains isolated in an active wool-cleaning factory.
Industrial Waste Industry Minisatellite Repeats Sheep wool Abstract: Culturable microorganisms from various samples taken at an active factory performing wool and goat hair cleaning were isolated and analyzed. ...
