Foot-and-mouth disease vaccine potency testing in cattle using homologous and heterologous challenge strains: precision of the "Protection against Podal Generalisation" test.
Foot-and-Mouth Disease Virus Viral Vaccines Abstract: The level of protection conferred by foot-and-mouth disease (FMD) vaccines in primovaccinated animals primarily depends on the potency of the vaccine and the ...
An international inter-laboratory ring trial to evaluate a real-time PCR assay for the detection of bovine herpesvirus 1 in extended bovine semen.
the sensitivity and specificity of the real-time PCR test was greater than those of virus isolation (82.7% versus 53.6% and 93.6% versus 84.6%, respectively). A high level of agreement on PCR testing ...
Uncertainty of measurement for competitive and indirect ELISAs.
result when retesting the same sample. For the competitive ELISA any sample with a percent inhibition 4% above the cut-off value had an uncertainty level (probability of a negative result in the case of ...
Pivotal role of ChIFNgamma in the pathogenesis and immunosuppression of infectious bursal disease.
divided into in vivo, ex vivo and in vitro experiments. Two-week-old specific pathogen free chickens were inoculated with the 849VB very virulent strain of IBDV. The levels of systemic ChIFNgamma and ...
Intake of ochratoxin A and deoxynivalenol through beer consumption in Belgium.
levels in conventionally and organically produced beers in 2003-05. For the consumers of organic beers, the daily intake of OTA was 0.86 (in 2003), 1.76 (in 2004) and 0.72 (in 2005) ng kg(-1) body weight ...
DNA immunization with plasmids encoding fusion and nucleocapsid proteins of bovine respiratory syncytial virus induces a strong cell-mediated immunity and protects calves against challenge.
elicited low antibody levels but primed a strong cell-mediated immunity characterized by lymphoproliferative response and gamma interferon production in vitro and in vivo. Interestingly, this strong cellular ...
Contaminants in organically and conventionally produced winter wheat (Triticum aestivum) in Belgium.
Pesticide residues Triticum Abstract: A database has been compiled with the levels of important contaminants (mycotoxins, heavy metals and pesticides) measured from 2002 to 2005 in winter wheat (Triticum ...
Development of an M2e-specific enzyme-linked immunosorbent assay for differentiating infected from vaccinated animals.
negative for the M2 e ELISA s. Moreover, ducks inoculated with inactivated vaccine and challenged with a HPAI H5N1 seroconverted for antibodies to the M2 e peptide, with significantly different levels from ...
Identification of Burkholderia pseudomallei and related bacteria by multiple-locus sequence typing-derived PCR and real-time PCR.
molecular diagnosis of these species hard to guarantee with a maximal confidence level. This article describes fast molecular assays derived from compiled sequences of housekeeping genes determined in more ...
Kinetic and biologic properties of recombinant ChIFN-gamma expressed via CELO-virus vector.
vector was able to replicate in vitro in the loghorn male hepatoma (LMH) hepatocyte cell line and to produce detectable levels of recombinant cytokine in supernatant as early as 90 min post-infection. ...
