Evaluation of tests for antibodies against bovine herpesvirus 1 performed in national reference laboratories in Europe.
Neutralization Tests Quality Control Reference Values Sensitivity and Specificity Vaccination Viral Proteins Viral Vaccines Abstract: Sets of serum and milk samples were collected from various countries and ...
Assessment of the cell-mediated immune response in chickens by detection of chicken interferon-gamma in response to mitogen and recall Newcastle disease viral antigen stimulation.
potential of a capture enzyme-linked immunosorbent assay (ELISA) specific for chicken interferon-gamma (ChIFN-gamma) has been evaluated as a tool to assess cell-mediated immunity (CMI) in the chicken. In ...
Molecular analysis of the capsid coding region of a virulent encephalomyocarditis virus isolate after serial cell passages and assessment of its virulence.
Cells, Cultured Encephalomyocarditis virus Genome, Viral Models, Molecular Mutation Serial Passage Swine Vaccines, Attenuated virulence Abstract: EMCV has been recognized as a worldwide-shared pathogen in ...
Development of a capture ELISA for the detection of antibodies to enteropathogenic Escherichia coli (EPEC) in rabbit flocks using intimin-specific monoclonal antibodies.
enzyme-linked immunosorbent assay (cELISA) was developed using intimin-specific monoclonal antibodies to detect specific antibody in rabbits that have been in contact with enteropathogenic Escherichia coli ...
Diagnosis of foot-and-mouth disease by RT-PCR: use of phylogenetic data to evaluate primers for the typing of viral RNA in clinical samples.
to different topotypes within each serotype. These interpretations were qualified by using a universal (FMD virus group) specific primer to confirm that FMD virus RNA had been extracted from the ...
Necrotoxigenic Escherichia coli type-2 invade and cause diarrhoea during experimental infection in colostrum-restricted newborn calves.
been developed with NTEC strains producing the cytotoxic necrotising factor 2. In all, 14 colostrum-restricted calves were orally challenged with two strains isolated from the faeces of a diarrheic calf ...
Molecular epidemiology of a large classical swine fever epidemic in the European Union in 1997-1998.
outbreaks were related and caused by a virus belonging to the genetic subgroup 2.1. As this type of virus had been reported infrequently in Europe and not at all since 1993, we postulate that it was newly ...
Classical swine fever virus: a ring test to evaluate RT-PCR detection methods.
coded samples were prepared by serial dilution of positive samples and then distributed to each of the laboratories. One set comprised 34 samples of random primed cDNA. These had been synthesised from ...
Clinical signs, reproduction of attaching/effacing lesions, and enterocyte invasion after oral inoculation of an O118 enterohaemorrhagic Escherichia coli in neonatal calves.
any of the three calves, nor were any lesions in the internal organs, which may have been related to the production of a verotoxin whose role is still unknown in cattle. Health Topics: Animal health ...
Diagnosis of foot-and-mouth disease by RT-PCR: evaluation of primers for serotypic characterisation of viral RNA in clinical samples.
Serotyping virology Abstract: Multiple primers designed from the 1D and 2AB regions of the foot-and-mouth disease (FMD) viral genome were evaluated extensively for the detection of all seven serotypes of the ...
