I am looking for basic references about E. coli O157:H7 strains that
do not have stx1 nor stx2. I would be grateful if someone could give
me some hints on where to start my literature search.
If E. coli O157:H7 negative for stx1 and stx2 is present, are strains
of E. coli O157:H7 likely present in the same sample?
Have strains of E. coli O157:H7 that do not have stx1 and stx2 been
implicated in illnesses?
Thanks in advance for your assistance.
