Surveillance épidémiologique des infections invasives causées par les streptocoques du groupe A S. pyogenes- 2017 à 2023
aussi un génotype plus virulent. • Les groupes d’âge les plus touchés sont les enfants de moins de 5 ans et les adultes de plus de 65 ans. • Il s’agit d’infections graves qui nécessitent presque toujours ...
Cytokine and immunoglobulin isotype profiles during CP7_E2alf vaccination against a challenge with the highly virulent Koslov strain of classical swine fever virus.
isotype-specific antibody profiles were investigated in CP7_E2alf vaccinated pigs before and after challenge with the highly virulent CSFV strain “Koslov” at 14 days or 6 months post-vaccination. The interference of ...
Efficacy of marker vaccine candidate CP7_E2alf against challenge with classical swine fever virus isolates of different genotypes.
usually carried out using highly virulent CSFV strains of genotype 1 that do not mirror the current field situation where strains of genotype 2 predominate. To prove that CP7_E2alf also protects against ...
Interaction of Aspergillus fumigatus conidia with Acanthamoeba castellanii parallels macrophage-fungus interactions.
avian macrophages. This suggests that A. fumigatus virulence mechanisms to evade macrophage killing may be acquired by co-evolutionary interactions among A. fumigatus and environmental amoebae. Health ...
Infectious Bursal Disease: a complex host-pathogen interaction.
virus, IBDV has a high mutation rate and may thus give rise to viruses with a modified antigenicity or increased virulence, as emphasized during the last decades. The molecular basis of pathogenicity and ...
Setting up a SPF chicken model for the pathotyping of West Nile virus (WNV) strains.
West Nile Fever West Nile virus Abstract: Birds play a central role in WNV epidemiology by spreading and amplifying the virus. Increasing numbers of WNV isolates are detected in Europe, and the virulence ...
