seems consequently to be within the upper range of cereulide
amounts reported in foods implicated in outbreaks.
Further characterization of the three isolates was performed
using repetitive sequence-based PCR (rep-PCR) and pulsed-
field gel electrophoresis (PFGE) (10, 11, 25) of genomic DNA.
All three strains displayed the same rep-PCR and PFGE pro-
files (data not shown).
