Project description:Regulation of EHEC gene expression by the gut commensal bacterium B. thetaiotaomicron. EHEC is a human pathogen that colonizes in the colon where B. thetaiotaomicron is a predominant commensal. We used microarrays to evaluate global regulation of EHEC when cultured with B. thetaiotaomicron.

EHEC is a human pathogen that colonizes in the colon where B. thetaiotaomicron is a predominant commensal. We used microarrays to evaluate global regulation of EHEC when cultured with B. thetaiotaomicron. EHEC and B. thetaiotaomicron were co-cultured in vitro under strict anaerobic conditions in low-glucose Dulbecco's modified Eagle's medium (DMEM). Total RNA from bacteria grown to mid-logarithmic phase was extracted and hybridized to an Affymetrix E. coli 2.0 gene chip according to manufacturer's specifications: http//www.affymetrix.com/support/technical/manual/expression_manual.affx
