Abstract
The Salmonella enterica smpB-nrdE intergenic region contains about 45 kb of DNA that is not present in Escherichia coli. This DNA region was not introduced by a single horizontal transfer event, but was generated by multiple insertions and/or deletions that gave rise to a mosaic structure in this area of the chromosome.
