A brief L.A. Times article came out yesterday on the atypical and difficult to trace E. coli outbreak that ran from May to July 2011 in Germany, which has been identified as a new strain (the article was featured by the Center for Infection and Immunity, who provides a lot of great reading in this area). If nothing else, getting fact-based information out there after the fact is important; there was a lot of misinformation going around on this one (the E. coli wound up coming from sprouts from Egypt). The information comes from a recently published article on the outbreak in the New England Journal of Medicine. A great quote from Dr. Martin J. Blaser in a related editorial:
This O104:H4 strain was well armed for mayhem and reminds us that evolution is a constant.
