B.thetaiotaomicron or B. longum mono-association versus B. thetaiotaomicron/B. longum co-colonization, PR chow, NMRI

Genome wide transcriptional comparison of B. thetaiotaomicron or B. longum mono-association vs. B. thetaiotaomicron bi-association with B. longum. Cecal populations from 10d colonizations with NMRI gnotobiotic mice fed a standard-chow polysaccharide rich (PR) diet (n=5 samples/group) were profiled. Keywords: Mono-association vs. Bi-association, in vivo Total RNA was prepared from cecal contents of 10 day associated gnotobiotic mice and hybridized to B. thetaiotaomicron/B. longum GeneChips.
