Purified genomic DNA from strain B cereus Elc2 was analyzed for genes encoding protective antigen (pagA), edema factor (cya), and lethal factor (lef) encoded by plasmid pXO1 in B anthracis and pBCXO1 in B cereus strain G9241.
Plasmid X01 carries the three toxin genes coding for edema factor, lethal factor and protective antigen (3).
The pXO1 plasmid contains genes lef cya, and pag, which encode the toxin's lethal factor, edema factor, and protective antigen, respectively (3-5).
