Abstract

One hundred and twenty Vero cytotoxin-producing (VT + ) strains of Escherichia coli 0157 (of H type 7 or non-motile) isolated in the UK, failed to ferment sorbitol after 24 h or to hydrolyse 4-methylumbelliferyl-beta-D-glucuronide (MUG).This combination of properties was not found in 167 of 169 other E. coli strains, including VT + strains of other serogroups and VT − strains of serogroup 0157. As the two exceptions were rare VT − strains of serotype 0157:H7, we conclude that, although biochemical tests can aid the isolation of VT + 0157 strains, confirmation of VT production is necessary
