Email Correspondence 7

Email correspondence 7/8/05 from Dayna Ferguson, MD, CDC Epidemic Intelligence Service Officer, CDPHE regarding the E.coli o157:MN outbreak in Georgia, 2004

Dear Mr. Rust:

“Thanks for your interest in the article.  I’ve attached a pdf copy per your request.  We did PFGE match the E. coli O157 isolates from Colorado and Minnesota.  The seed lots in these two outbreaks were different although they both traced back to seeds from the same producer in Australia.

Although the isolates from Georgia were also a PFGE match, Georgia was not included in this report.”

Dayna Ferguson
