Assessment of genetic, antigenic and pathotypic criteria for the characterization of IBDV strains.
indicate the probable existence of differences in virulence within IBDV lineages determined on the basis of antigenic typing using monoclonal antibodies and the alignment of the VP2 sequences. This indicates ...
Phylogenetic analysis of fowl adenoviruses.
United States Abstract: The sequences of the L1 loop of the hexon protein from representative fowl adenovirus (FA dV) strains of the different European and American collections were determined and ...
Decision support tools for clinical diagnosis of disease in cows with suspected bovine spongiform encephalopathy.
25 signs, was made between all 30 BSE cases, confirmed in Belgium before October 2002, and 272 suspected cases that were subsequently determined to be histologically, immunohistochemically, and ...
Protein growth rate in rainbow trout (Oncorhynchus mykiss) is negatively correlated to liver 20S proteasome activity.
We selected fish for high and low growth efficiencies. Protein degradation was estimated from the difference between protein synthesis (determined by 15N flux) and protein growth. We found that protein ...
Evaluation of virulence of Mycoplasma hyopneumoniae field isolates.
genetic differences as determined by randomly amplified polymorphic DNA (RAPD) analysis. Ninety, conventional M. hyopneumoniae-free piglets were inoculated intratracheally with the field isolates, ...
Assessment of the clinical and virological protection provided by a commercial inactivated bovine viral diarrhoea virus genotype 1 vaccine against a BVDV genotype 2 challenge.
carried out to determine the cross-protective efficacy of a commercial inactivated vaccine containing a BVDV-1 strain. A group of five BVDV-free calves was vaccinated twice and a second group of five calves ...
Worker caste polymorphism has a genetic basis in Acromyrmex leaf-cutting ants.
resulting from interplay between nurture and nature. Unlike the few other recently discovered examples of a genetic influence on caste determination, the present result does not relate to any rare or ...
Dual labeling of Pseudomonas putida with fluorescent proteins for in situ monitoring of conjugal transfer of the TOL plasmid.
discriminated on the basis of their fluorescence by using confocal laser scanning microscopy. Conjugal plasmid transfer frequencies on agar surfaces and in sludge microcosms were determined microscopically ...
Development of a capture ELISA for the detection of antibodies to enteropathogenic Escherichia coli (EPEC) in rabbit flocks using intimin-specific monoclonal antibodies.
positive controls. These were used to determine a cut-off value for a positive cELISA result. The value selected gave the test a sensitivity of 80.0% and a specificity of 98.4% on an individual level. At ...
Patterns of Mycoplasma hyopneumoniae infections in Belgian farrow-to-finish pig herds with diverging disease-course.
determine the infection pattern of Mh and the clinical course of the infection. Health Topics: Animal health Category: A1 FOS Classification: 4.03 Veterinary science ...
