Sentence examples for virulence vector from inspiring English sources
But many other factors also contribute to this difference, such as the type of parasite and its level of virulence, vector control measures, rates of host immunity, access to healthcare and other socioeconomic factors.
The same virulence vectors may affect in future the environmental and conditionally pathogenic Mycobacteria.
In addition, LACV isolations are needed so West Virginian virus strains can be compared with virus strains from other regions to determine if differences exist in virulence and vector competence.
In addition, a coupling of viral fitness and vector virulence could add further to this evolutionary constraint.
The notion that individual strain fitness and vector virulence may be coupled, as predicted by the trade-off hypothesis and demonstrated here, could fundamentally change our understanding of how vector-virus interactions work to shape the evolutionary trajectories of arboviruses and other vector-borne pathogens.
Optimization of the vector included virulence attenuation and determination of the N-terminal sequence allowing translocation of fused antigens into cells.
The insertion of either version of the HA ORF did not increase the virulence of the rNDV vector.
Because expression of the H5 HA protein of a highly pathogenic HPAIV, and in particular its incorporation into the NDV virion, may alter the virulence of the NDV vector, we examined the pathogenicity of the recombinant viruses by the MDT method in embryonated chicken eggs [32].
This method allowed to avoid issues related to the immunogenicity and virulence of the viral vector in the virus-based transfection.
Additionally, changes in virus strain virulence, the distribution of vector species, land use patterns, forest succession and/or increased human encroachment into enzootic foci could also be contributing factors.
In addition, for those vertebrate pathogens that are vectored by arthropods, selection by the invertebrate innate immune system could shape the virulence of vertebrate pathogens vectored by invertebrates [ 16].
