Enterohemorrhagic Escherichia coli Exploits EspA Filaments for Attachment to Salad Leaves

Abstract
Enterohemorrhagic Escherichia coli (EHEC) strains are important food-borne pathogens that use a filamentous type III secretion system (fT3SS) for colonization of the gut epithelium. In this study we have shown that EHEC O157 and O26 strains use the fT3SS apparatus for attachment to leaves. Leaf attachment was independent of effector protein translocation.
