Journal of microbiology & biology education the recombination-based in vivo expression technology (rivet) identified with recombinase-based screening . In vivo induced antigen technology (iviat) is an immuno-screening technique designed to identify immunogenic bacterial genes expressed specifically during infection – we hypothesized that applying iviat to bacillus anthracis , the cause of anthrax, could lead to increased understanding of bacterial events during infection, improved . Using recombinase-based in vivo expression technology (rivet), another group has also reported that spi-2 is expressed prior to bacterial penetration of the epithelial layer in a murine model of salmonellosis the considerable differences in pathology and host response between the bovine and mouse models of salmonellosis, in addition to . To investigate e faecalis factors required for commensalism, we identified e faecalis genes that are up-regulated in the gut of m sexta using recombinase-based in vivo expression technology .

In vivo expression technology strategies: valuable tools for biotechnology this brief review is rivet recombinase-based ivet intended to draw attention to ivet . Recombinase-based in vivo expression technology (rivet) involves the reporter gene, tnpr, whose protein product excises a resolvase substrate cassette (res1-tet-res1) prescreening is required to remove strains harboring gene fusions that are active in vitro. The expression of tcpa and ctxa was examined during intestinal infection using a recombinase based in vivo expression technology (rivet) the contributions of toxr, tcpp and toxt in tcpa and ctxa expression were found to differ significantly during infection compared to growth in vitro .

Temporal expression patterns of the alcaligin, enterobactin and heme systems were examined using recombinase-based in vivo expression technology (rivet) in a mouse respiratory infection model (brickman et al 2008) the three systems were found to be differentially expressed in vivo, showing early induction of the alcaligin and enterobactin . Finally, the third aim of the proposal will establish the temporal and spatial regulation of white- opaque switching in the mammalian host using rivet (recombinase in vivo expression technology) thus, taken together, the proposed studies will determine both the in vitro regulation of the white-opaque switch by environmental and host factors .
