Influence of temperature, oxygen and bacterial strain identity on the association of Campylobacter jejuni with Acanthamoeba castellanii.
sources of poultry. In this study, the ability of five Campylobacter jejuni strains with different invasion potential towards Caco-2 cells to survive and replicate in the protozoan Acanthamoeba castellanii ...
The positive adjuvant effect of chitosan on antigen-specific cell-mediated immunity after chickens vaccination with live Newcastle disease vaccine.
It has been demonstrated to be an effective absorption enhancer to improve mucosal delivery of peptide and protein drugs in human and mice. In poultry, mucosal administration of live vaccine has been ...
Passive protection afforded by maternally-derived antibodies in chickens and the antibodies' interference with the protection elicited by avian influenza-inactivated vaccines in progeny.
plan that could be applied nationwide to all commercial and backyard poultry. However, after several months of vaccination in enzootic areas, maternally derived antibody (MDA) is present in young chicks, ...
Identification of a dominant epitope in the hemagglutinin of an Asian highly pathogenic avian influenza H5N1 clade 1 virus by selection of escape mutants.
Molecular Mutation Neutralization Tests Viral Proteins Abstract: H5N1 avian influenza virus has caused widespread infection in poultry and wild birds, and has the potential to emerge as a pandemic threat to ...
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.
Immunosorbent Assay Influenza A virus Influenza in Birds Poultry Reagent Kits, Diagnostic Sensitivity and Specificity Seroepidemiologic Studies Abstract: Since the emergence of the highly pathogenic avian ...
Evaluation of different serologic markers for the early detection of avian influenza infection in chickens.
Biomarkers Chickens Influenza A virus Influenza in Birds Specific Pathogen-Free Organisms Abstract: Viruses of all subtypes may be introduced into domestic poultry, but only H5 and H7 low pathogenicity avian ...
Improved vaccination against Newcastle disease by an in ovo recombinant HVT-ND combined with an adjuvanted live vaccine at day-old.
fatal Newcastle disease (ND) in commercial poultry flocks demonstrate that current vaccination strategies are not fully efficacious and should be improved by new generation of vaccines. In this context, ...
Characterization of pathogenic and resistant genome repertoire reveals two clonal lines in Salmonella enterica subsp. enterica serovar Paratyphi B (+)-tartrate positive.

The role of the legal and illegal trade of live birds and avian products in the spread of avian influenza.
guidelines. Nevertheless, the balance between acceptable risk and safe trade is difficult to achieve. Since the movements of poultry and birds are sometimes difficult to trace, the signature or ‘identity card’ ...
