Segments used to search the nr database.

aHits align over at least 50% of the query length.bp is the probability that a hit is EHEC.cIncludes Citrobacter rodentium ICC168, a strain that is known to have acquired EHEC and EPEC associated sequences from E. coli[21].dHits in bacteriophage genomes were not counted.ePlus sign indicates that length is ≥200 bp and p is >0.80. Segments indicated by + would be useful as PCR probes to detect EHEC strains.
