B.thetaiotaomicron mono-association versus B. thetaiotaomicron co-colonization with B. animalis or L. casei, PR chow, B6

ABSTRACT: Genome wide transcriptional comparison of B. thetaiotaomicron mono-association vs. B. thetaiotaomicron bi-association with B.animalis or L. casei. Cecal populations from 20d colonizations with B6 gnotobiotic mice fed a standard-chow polysaccharide rich (PR) diet (n=5 samples/group) were profiled. Total RNA was prepared from cecal contents of 20 day associated gnotobiotic mice and hybridized to B. thetaiotaomicron/B. longum GeneChips.

Probiotics are deliberately ingested preparations of live bacterial species that confer health benefits on the host. Many of these species are associated with the fermentation of dairy products. Despite their increasing use, the molecular details of the impact of various probiotic preparations on resident members of the gut microbiota and the host are generally lacking. To address this issue, we colonized germ-free mice with Bacteroides thetaiotaomicron, a prominent component of the adult human  ...[more]
