Project description:Transcriptional profiling of Bacteroides thetaiotaomicron was performed on samples taken from (i) chemostat cultures (in vitro) and (ii) from the ceca of gnotobiotic monoassociated NMRI mice (in vivo). In vitro profiles were obtained from biological duplicate cultures taken at five timepoints from log to stationary phase in three types of media: (i) minimal media glucose (MM-G), (ii) minimal media maltotriose (MM-M), and (iii) rich media (TYG). In vivo profiling was performed on 12 mice, each colonized with B. thetaiotaomicron for ten days. The in vivo profiling was conducted in two separate experiments: (i) 6 male NMRI mice fed standard polysaccharide rich mouse chow and (ii) 3 male NMRI mice fed standard polysaccharide rich mouse chow and 3 male NMRI mice fed a simple sugar diet containing glucose and sucrose but deficient in polysaccharides.

Project description:Genome wide transcriptional comparison of B. thetaiotaomicron wild type vs. an isogenic mutant (BT2923::pGERM). Cecal populations of wt or BT2923::pGERM monoassociated 10d with B6 or NMRI gnotobiotic mice fed a standard-chow polysaccharide rich (PR) diet were profiled. Keywords: wild type versus knockout, in vivo
Project description:Genome wide trascriptional comparison of B. thetaiotaomicron wild-type vs. an isogenic mutant (BT3172::pGERM). Cecal populations of wt or BT3172::pGERM monoassociated 10d with NMRI gnotobiotic mice fed a standard-chow polysaccharide rich (PR) diet (n=5 samples/group) were profiled. Keywords: Wild-type versus Knockout, in vivo
