Quantitative characterization of agglomerates and aggregates of pyrogenic and precipitated amorphous silica nanomaterials by transmission electron microscopy.
characterize the aggregates and agglomerates of precipitated and pyrogenic synthetic amorphous silicon dioxide (SAS), or silica, NM. RESULTS: Bright field (BF) TEM combined with systematic random imaging and ...
Viral RNA load in semen from bluetongue serotype 8-infected rams: relationship with sperm quality.
be predictive of sperm quality. Semen samples were collected on six occasions from 93 BTV-8 infected rams involved in two longitudinal (n=12 and 27, respectively) and one cross-sectional (n=54) field ...
Potential impact of fertilization practices on human dietary intake of dioxins in Belgium.
contamination data taken from the literature, we estimated that fertilization accounts for approximately 20% of the dioxin inputs on agricultural soils at country scale. For the estimations at the field scale, ...
Development and inter-laboratory validation study of an improved new real-time PCR assay with internal control for detection and laboratory diagnosis of African swine fever virus.
Africa. Compared to the OIE-prescribed conventional and real-time PCR assays, the sensitivity of the new assay with internal control was improved, as demonstrated by testing 281 field samples collected in ...
Nucleotide polymorphism-based single-tube test for robust molecular identification of all currently described Brucella species.
(MLST) database that has been extensively validated on hundreds of different Brucella strains. When assayed on both reference and field strains, the method yields characteristic capillary electrophoresis ...
Capsid proteins from field strains of foot-and-mouth disease virus confer a pathogenic phenotype in cattle on an attenuated, cell-culture-adapted virus
cDNA was derived from the cell-culture-adapted O1K aufbeuren B64 (O1K B64) strain. Chimeric viruses, containing capsid coding sequences derived from the O/ UKG /34/2001 or A/Turkey 2/2006 field viruses, ...
Classical swine fever: comparison of oronasal immunisation with CP7E2alf marker and C-strain vaccines in domestic pigs.
replication site of CP7E2 alf vaccine virus was found to be the tonsils as in the C-strain and virulent field strains. Persistence of CP7E2 alf in the tonsils was also demonstrated up to 63dpv. Both vaccines ...
Fine quantification of avian influenza H5N1 escape mutant quasispecies populations using mutation-specific real-time PCR.
detection of critical changes in the field situation. Health Topics: Animal health Category: A1 FOS Classification: 4.03 Veterinary science ...
Evaluation of different strategies for the use of ELISA tests as first screening tools for serologic surveillance of low pathogenic avian influenza in the Belgian poultry sector.
were then tested using approximately 800 field sera representative of different poultry species, and a simulation was done to determine the best strategy for screening. The first strategy was testing ...
Evaluation of different serologic markers for the early detection of avian influenza infection in chickens.
influenza viruses can mutate during circulation in poultry and emerge as high pathogenicity avian influenza variants. It is therefore essential to monitor the field situation continuously to detect low ...
