The O-antigen (rfb) operon and related genes of MA6, an O rough:H7 Shiga-toxigenic Escherichia coli strain, were examined to determine the cause of the lack of O157 expression. A 1,310-bp insertion, homologous to IS629, was observed within its gne gene. trans complementation with a functional gne gene from O157: H7 restored O157 antigen expression in MA6.
