RFLP of phage from stx2-positive and stx-negative isolates.
EcoRI restriction fragment length polymorphism analysis of Stx2 phage and stx-negative phage in EHEC O103:H25 NOS and E. coli O103:H25 NVH-848, respectively. The arrow indicates the EcoRI fragments that are indistinguishable between the strains, arrowhead indicates the EcoRI fragment of E. coli O103:H25 NOS where the stx2 gene is located.
