The combination of attenuated Newcastle disease (ND) vaccine with rHVT-ND vaccine at 1 day old is more protective against ND virus challenge than when combined with inactivated ND vaccine.
the same age in commercial layer chickens. The humoral, cell-mediated and local immunity were followed weekly and birds were challenged with a viscerotropic velogenic ND virus strain at 6 and 10 weeks ...
Characterization of methicillin-resistant Staphylococcus aureus from healthy carrier chickens.
livestock including poultry, little is known about the epidemiology of MRSA in broiler and layer chickens. We therefore investigated 372 poultry farms in Belgium. We also compared the isolation method ...
Accuracy profiles assessing the validity for routine use of high-performance thin-layer chromatographic assays for drug formulations
thin-layer chromatography (HPTLC) methods, which initially were validated using the classic approach. The first method assayed sulfamethoxazole and trimethoprim, and the second lamivudine, stavudine and ...
Efficacy of rHVT-AI vector vaccine in broilers with passive immunity against challenge with two antigenically divergent Egyptian clade 2.2.1 HPAI H5N1 strains.
H5N1 Subtype Influenza in Birds Influenza Vaccines Vaccines, Inactivated Abstract: In countries where avian influenza has become endemic, early vaccination of layer pullets or broilers with classical ...
Polyphasic characterization of Salmonella Enteritidis isolates on persistently contaminated layer farms during the implementation of a national control program with obligatory vaccination: a longitudinal study34033
Enteritidis isolates on 5 persistently contaminated Belgian layer farms and to examine the potential sources and transmission routes of Salmonella Enteritidis contamination on the farms during successive laying ...
Molecular characterization of Salmonella Enteritidis: comparison of an optimized multi-locus variable-number of tandem repeat analysis (MLVA) and pulsed-field gel electrophoresis.
Wallace coefficient (W) was calculated to assess the congruence of the typing methods. Selection of epidemiologically unrelated isolates and more related isolates (originating from layer farms) was also ...
Potential impact of fertilization practices on human dietary intake of dioxins in Belgium.
1 and 3 ng TEQ /m² and sludge or compost bring more than 3 ng TEQ /m². The use of solid fertilizers could potentially increase the dioxin levels in the 30 cm agricultural soil layer by 0 to ~1.5% per year ...
Skin mucus of Cyprinus carpio inhibits cyprinid herpesvirus 3 binding to epidermal cells.
where the mucus was removed with or without associated epidermal lesion. To investigate whether skin mucus inhibits CyHV-3 binding to epidermal cells, tail fins with an intact mucus layer or without mucus ...
Comparison of Salmonella enteritidis phage types isolated from layers and humans in Belgium in 2005.
(2004/665 EC) on Salmonella in layers in 2005, as well as the results of the monthly outbreak reports of Salmonella Enteritidis in humans in 2005 to identify a possible statistical significant trend in ...
Aggregate size and architecture determine microbial activity balance for one-stage partial nitritation and anammox.
Large reactor B aggregates were thin film-like nitrite sinks (NARR, <0.5) in which AnAOB were not shielded by an AerAOB layer. Voids and channels occupied 13 to 17% of the anoxic zone of AnAOB-rich ...
