Gram Negative Bacilli
Verocytotoxin is secreted by:
|A||Enterotoxigenic Escherichia coli|
|B||Enteroinvasive Escherichia coli|
|C||Enterohaemorrhagic Escherichia coli|
|D||Enteropathogenic Escherichia coli|
Verocytotoxin is produced by EHEC.
Its mechanism of action is similar to shiga toxin of S. dysenteriae, hence also called Shiga-like toxin.
It is a phage mediated toxin. It is the commonest cause of HUS.
