Selected BBG polymorphisms in comparison to reference strain Sakai (CG-3).

aSakai strain (CG-3) chromosomal location, in silico BamHI fragments, and features present in the polymorphic region.bGenes cited are known Stx-associated bacteriophage insertion sites. In Sakai, Sp5 is the Stx2-associated bacteriophage inserted in wrbA and Sp15 is the Stx1-associated bacteriophage inserted in yehV; Sp = Sakai prophage; SpLE = Sakai prophage like elements.cBBG isolate(s) in which the polymorphism was detected; 1: E5880; 2: E3855; 3: E2039; 4: E6996.dStx-associated bacteriophage potentially involved in polymorphism based on optical maps.
