Sampling strategy, occurrence and diversity of free-living protozoa in domestic refrigerators.
seeded with representatives of FLP were swabbed with cotton wools. The recovery efficiency was the highest for Chilomonas paramecium, followed by Tetrahymena pyriformis and the lowest for Acanthamoeba ...
Classical swine fever: comparison of oronasal immunisation with CP7E2alf marker and C-strain vaccines in domestic pigs.
vaccine candidate (CP7E2 alf) has been recently developed (Reimann et al., 2004). This communication reports the comparison of CP7E2 alf and C-strain virus vaccines during 98 days following oronasal ...
A proposed validation method for automated nucleic acid extraction and RT-qPCR analysis: an example using Bluetongue virus.
Transcriptase Polymerase Chain Reaction Validation Studies as Topic Abstract: This study proposes a validation strategy for an automated extraction procedure, followed by RT-qPCR analysis. To avoid false-negative ...
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.
screening tool to test all the poultry sera, followed by confirmation by H5 and H7 HI test subtyping. Health Topics: Animal health Category: A1 FOS Classification: 4.03 Veterinary science ...
Development of specific enzyme-linked immunosorbent assays to evaluate the duck immune response after experimental infection with H5N1 and H7N1 low pathogenic avian influenza viruses.
developed tools. In the two studies, systemic and mucosal AIV-specific duck IgY, Ig (light chain), IgY (heavy chain), IgA, and IgM were detected and followed. Therefore, the developed ELISA s proved to be ...
Evaluation of different serologic markers for the early detection of avian influenza infection in chickens.
evaluation of the degree of adaptation and the timing of infection. Therefore, several experimental infections of specific-pathogen-free chickens were conducted to follow the kinetics of antibody responses ...
The most likely time and place of introduction of BTV8 into Belgian ruminants.
a large anonymous, random postal survey of cattle herds and sheep flocks; a random historical milk tank survey of samples tested with an indirect ELISA and a follow-up survey of non-specific health ...
Induction of Mx and PKR failed to protect chickens from H5N1 infection.
response in chickens after hpH5N1 infection, or how the virus is evolving to modify and evade host protective responses. Therefore, to better understand the chicken immune response following hpH5N1 ...
Experimental reproduction of bluetongue virus serotype 8 clinical disease in calves.
Transcriptase Polymerase Chain Reaction RNA, Viral Viremia Abstract: Cattle are commonly subclinically infected following natural or experimental infection with bluetongue virus (BTV). The introduction of BTV ...
Type and frequency of contacts between Belgian pig herds.
number of onto-farm movements according to herd size and herd type. Piglet multipliers followed by finishing herds were predicted to have the most onto-farm movements. Farrow-to-finishing herds made less ...
