^aOnly those carbon sources that were oxidized at an average rate of at least 2 times the negative control value (60 out of 192 carbon sources) are shown. Numbers in boldface indicate a standard deviation of catabolic activity larger then 1, indicating considerable diversity among the E. coli O157 isolates.
