The German Consiliary Center for EHEC
has identified EHEC
producing Shiga toxin 2 (Stx2), as the causative agents.

O157 lacks diversity in its housekeeping genes (21,22), which hampers phylogenetic analysis of EHEC

There is no specific medium for detection of non-O:157 strains of EHEC
, but plates can be submitted to public health laboratories, which are equipped for isolation and strain typing of these organisms.
LIMITATIONS: Recognised classes of Escherichia coli (EPEC, ETEC, EHEC
, EAEC and EIEC) were not isolated due to lack of facility in the institution.
At present there is no proven active treatment for EHEC
infection or HUS.
coli (EPEC) shares several key virulence determinants with the most common varieties of EHEC
but neither produces shiga toxins nor causes HC or HUS.
EF-P plays a crucial role in the production of proteins that are essential for the virulence of EHEC
