The basic principle here relies on creating conditions that stimulate natural selection for SRE at the expense of other (saprophytic) bacteria.
This result can be explained by the fact that gradual increase in salinity will stimulate the selection of dense flocs with minimum washout (as observed in SBR1), while sudden salt increase (as performed in SBR2) enhances water density, which can cause excessive washout of biomass (Moussa et al. 2006).
The beefed-up Literature & Fiction section projects something of a salon feel, with a stimulating selection of writers naming their favorites books of the year.
This approach should stimulate the self-selection of workers into either early retirement or job search, even in a world of imperfect observability.
As in S. dozieri, the repertoire of sexual behaviour which all these species display has yet to be characterised but such examples will hopefully stimulate interest in sexual selection in species such as these.
It then goes on to recount a brief history of vaccination, outlines factors likely to influence the outcome of vaccine administration and describes the immune response stimulated by a selection of commercial and experimental vaccines.
Among all biomaterials targeted for phage display selection, directly using whole cells as selection target has many advantages: 1) it needs no further information about cell surface molecules or purification of these molecules; 2) the surface molecules are most likely in their original state; 3) the selection stimulates the native binding environment where other macromolecules coexist.
To address this question, we performed in vitro co-culture experiments with mouse and human epithelial cell lines stimulated with a selection of Helicobacter spp., including known pathogenic species as well as ones for which the pathogenic potential is less clear.
We sought to address this question by studying NF-κB and/or CXC chemokine responses in epithelial cell lines stimulated with a selection of intestinal Helicobacter spp. This work has allowed us to identify, for the first time, the contribution of two PRMs, TLR2 and NOD1, in innate immune recognition of a commensal Helicobacter sp. of the normal rodent flora.
These data show that some M. tuberculosis strains persist longer than others after transient exposure to low concentrations of rifampin, which could create a wider window for the (possibly stimulated) generation and selection of resistant mutants.
