Map of Genome Sequence for E. coli Strain (image) University of California - San Diego Caption UC San Diego bioengineers have completed the genome sequencing of a particularly harmful strain of E. coli that has been tied to outbreaks of food poisoning. The circular map shows the completed sequence with lighter color regions representing gaps in a 2001 sequencing of the strain that have now been completed with current technology.
