As it was suggested by Kat Holt (http://bacpathgenomics.wordpress.com/2011/06/05/ehec-genomes-snp-locations/) and others a plasmid very similar to pEC_Bactec is a part of the genome of the recently sequenced EHEC H112180280 strain.
The figure displays a simple alignment obtained using MAUVE Move Contigs tool between pEC_Bactec plasmid (above) and the scaffolds 7 and 13 of H112180280 genome (below):
Scaffolds 7 and 13 cover practically all pEC-Bactec plasmid sequence. The two white
pEC-Bactec regions that hasn’t associated similar regions in
H112180280 correspond to the genes:
TnpA OrfB IS66(the left white region into the red similarity block)
TnpA IS26transposase (The white patch into the blue block)
H112180280 sequence regions without any similarity conexion with
pEC-Bactec flanking the two little green blocks correspond to N regions that remain undefined in the
H112180280 sequence obtained with paired end 454 technology.
