Studies from G.H. Wu and colleagues yield new information about Escherichia coli

Among 26 test strains, 24 (including both Shiga toxin [Stx]-positive and -negative strains) were found to be related to the two sequenced E. coli 0157:117 strains, EDL933 and Sakai." "However, these strains showed much greater genetic diversity than those reported previously, and most of them could not be categorized as either lineage I or H. Some genes were...
