Prime-boost vaccination with a fowlpox vector and an inactivated avian influenza vaccine is highly immunogenic in Pekin ducks challenged with Asian H5N1 HPAI.

a synthetic HA gene from an Asian H5N1 isolate (A/chicken/Indonesia/7/2003). Full protection against clinical signs and shedding was induced by the different vaccination schemes. However, the broadest antibody ...

Some guidelines for determining foot-and-mouth disease vaccine strain matching by serology.

of foot-and-mouth disease (FMD) virus can be assessed in vivo or by serological r-value determination. Sera from animals involved in vaccine potency and cross-protection trials performed using the ...

Prevaccination distribution of human papillomavirus types in women attending at cervical cancer screening in Belgium.

the expected and theoretical levels of vaccine protection offered as vaccinated girls gradually age into the groups from which our observations stem. Further periodic laboratory-based surveys, including ...

Immunogenicity and protective efficacy of tuberculosis subunit vaccines expressing PPE44 (Rv2770c).

intratracheal challenge with M. tuberculosis resulted in a protective efficacy comparable to the one afforded by BCG. Taken together these results indicate that PPE44 of M. tuberculosis is a protective antigen ...

The polymeric stability of the Escherichia coli F4 (K88) fimbriae enhances its mucosal immunogenicity following oral immunization.

available against intestinal infections since the induction of a protective intestinal immune response is difficult to achieve. For instance, oral administration of most proteins results in oral tolerance ...

Immunogenicity and protective efficacy of DNA vaccines encoding MAP0586c and MAP4308c of Mycobacterium avium subsp. paratuberculosis secretome.

identified. Finally, MAP infected mice generated strong MAP0586 c-specific T cell responses and MAP0586 c DNA vaccination could protect BALB /c but not C57BL /6 mice against MAP challenge mice to the same ...

Indirect foot-and-mouth disease vaccine potency testing based on a serological alternative.

serum titres of primo-vaccinated cattle and protection against infection have been proposed, but none have been accepted by the European Pharmacopoeia (Ph.Eur.) due to the lack of statistical power and ...

protection réglementation risques santé santé publique SBB Technique Type website Abstract: Ce document a pour but de donner un aperçu des critères de décision qui mènent au choix d’uneprotection respiratoire ...

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 ...
