Although these genes may not significantly favor host susceptibility, they do not appear to be elicitors of an HR response either.
The coevolution of Agrobacterium and its plant hosts may favor the integration of transgenes into genomic loci that are transcriptionally active, which leads to its high level of expression [ 7].
As integrated elements prophages gain a benefit from polylysogeny through increased fitness of their host; therefore, it may be imagined that between-host selection may favor phages that accommodate superinfection.
Equally important is to determine the virulence of Salmonella strains which may favor systemic dissemination in the host.
Easy access to blood sources in any host – vector interaction can be of crucial epidemiological significance because increased frequency of host-biting may favor the spread of infectious disease present.
He postulates that cytokines secreted by the host during ARDS may favor the growth of some strains of bacteria and consequently explain the association between exaggerated and protracted systemic inflammation and the development of nosocomial infections [ 1].
Although selection may favor Neotyphodium genotypes that are strongly mutualistic for host plants, changes in the effectiveness levels induced by the host plant response to environmental heterogeneous conditions or changes in their genotypes are likely to break down the mutualism stability (Saikkonen et al. 2004; Thompson 2005).
Similarly, brood parasitism from Brown-headed Cowbirds may favor smaller nests if cowbirds use visual cues to detect host nests [52].
In so doing, selection may favor the acquisition or loss of certain genes depending on the host.
Therefore, PI4KCA is not required for evasion of lysosomal fusion, but it is essential for bacterial proliferation in the host cytosol, where many transduction pathways downstream of PI4KCA may favor intracellular replication of F. tularensis.
