Bubonic plague DNA in e.coli O104:H4?

From Food Freedom blog:

Food Freedom has deliberately refrained from posting any suggestion that Germany’s superbug is related to biowarfare, until further evidence emerged.

Various sources now corroborate this story, including The Atlantic:

“On Tuesday [May 31], the German newspaper Süddeutsche Zeitung reported that [leading German E. coli researcher Helge] Karch had discovered that the O104:H4 bacteria responsible for the current outbreak is a so-called chimera that contains genetic materia from various E. coli bacteria. It also contains DNA sequences from plague bacteria, which makes it particularly pathogenic.”
