E. coli outbreak in Oklahoma

Over 42 instances of infections with pathogenic Escherichia coli have been reported in NE Oklahoma recently. Samples have been sent to the CDC, so the strain responsible should be known shortly.

Though it doesn't say specifically, the symptoms sound like this is caused by a enterohemmorhagic (EHEC) strain of E. coli. The strain O157:H7, often referred to as the "Jack in the Box" strain, is an EHEC strain.
