Complete Genome Sequencing of the Mouse Intestinal Isolate Escherichia coli Mt1B1

ABSTRACT Escherichia coli Mt1B1, a mouse isolate, is a facultative anaerobic bacterium which was shown to counteract Salmonella enterica serovar Typhimurium infection in a mouse model. In the present study, we describe the complete genome sequence of E. coli Mt1B1, composed of a 5.1-Mb chromosome and a 62.6-kb plasmid.
