摘要：

One hundred and twenty Vero cytotoxin-producing (VT+) strains of Escherichia coli O157 (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 O157. As the two exceptions were rare VT- strains of serotype O157:H7, we conclude that, although biochemical tests can aid the isolation of VT+ O157 strains, confirmation of VT production is necessary.
