Characterisation of the pO157 plasmid in STEC
The pO157 plasmid in STEC isolate Sakai encodes a type 2 secretion system along with putatively secreted toxin genes and proteases. Here we cured isolate Sakai of the pO157 plasmid in order to determine whether any of the genes on the plasmid played a role in plant-microbe interactions.
