Emergence of a novel Shiga toxin-producing Escherichia coli O serogroup cross-reacting with Shigella boydii type 10

Abstract

This is the first report of the isolation of Shiga toxin-producing Escherichia coli (STEC) strains whose O antigens were genetically and serologically identical to those of Shigella boydii type 10, from human feces. The novel STEC O serogroup may be widespread in Japan and associated with diarrhea and hemorrhagic colitis.
