PFGE is used to create a DNA "fingerprint" to
detect and track bacterial strains associated with foodborne outbreaks
at the state and national levels. When an E. coli 0157:H7, Shigella,
or Salmonella is identified, it is "fingerprinted" by
PFGE and its pattern is compared to other patterns from that same
serotype throughout the state
, and nation. Any
pattern matches within a similar time frame are brought to the
attention of the State Epidemiologist and the Centers For Disease
Control and Prevention in Atlanta, GA.
Additional information on PFGE can be found at http://www.cdc.gov/pulsenet/.
