Role of the Bacteroides fragilis EcfO regulon during oxidative stress.

Genome expression study of Bacteroides fragilis strain 638R comparing an ecfO null mutant with an empty vector to a reo (anti-ecfO) null mutant containing the ecfO gene on a plasmid under the control of an IPTG inducible promoter. Seven chip study with 8 technical replicates (i.e. Each probe replicated 8 times on the chip) on each chip comparing the ecfO overexpressing strain in a reo (anti-ecfO) mutant to an empty vector control in an ecfO null mutant.
