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.
combination. Therefore, broilers carrying MDA s against both HVT and Asian H5N1 HPAIV were vaccinated on the first day of age with rHVT- H5, with or without boosting vaccination by an inactivated vaccine after ...
Potency of a recombinant NDV-H5 vaccine against various HPAI H5N1 virus challenges in SPF chickens.
viruses. Obtained protections were dependent on the age of the chickens, on the constructs and, in particular, on the homology between the HA that was inserted and the challenge strains. The objective of ...
Spatiotemporal dynamics of Puumala hantavirus in suburban reservoir rodent populations.
vole density, vole weight (a proxy for age), and capture site but not by year or sex. Moreover, voles with large maximal distance between two captures had a high probability for Puumala seropositivity. ...
Risk factors associated with brucellosis seropositivity among cattle in the central savannah-forest area of Ivory Coast.
Abstract: Serological results obtained from 907 serum samples collected from unvaccinated cattle of at least 6 months of age in the savannah-forest region of Ivory Coast were used to investigate risk factors ...

Efficacy of marker vaccine candidate CP7_E2alf in piglets with maternally derived C-strain antibodies.
vaccinated once intramuscularly with C-strain vaccine 4 weeks before farrowing. Thus, these piglets were vaccinated intramuscularly with CP7_E2alf at the age of 5 or 8 weeks. Subsequently, the piglets and ...
Bluetongue sentinel surveillance program and cross-sectional serological survey in cattle in Belgium in 2010-2011.
expected prevalence of 2% and 95% confidence level. The study of the maternal antibodies in non-vaccinated animals showed that by the age of 7 months maternal antibodies against BTV had disappeared in most ...

Sero-epidemiological study of the presence of hantaviruses in domestic dogs and cats from Belgium.
of the owner’s address as well as pet gender and age on hantavirus status. Hantavirus antibodies were found in both species with a significantly higher seroprevalence in cats than in dogs (16.9% vs. ...
Effect of coated and non-coated fatty acid supplementation on broiler chickens experimentally infected with Campylobacter jejuni.
period (1-42 days), the chickens were fed a diet supplemented with 0.25% caprylic and capric acid (1:1), coated or non-coated. At the age of 14 and 28 days, chickens were orally challenged with C. jejuni. ...
