Production of verotoxin and distribution of O islands 122 and 43/48 among verotoxin-producing Escherichia coli O103:H2 isolates from cattle and humans.
This study investigated variations in the occurrence of markers of O islands 122 and 43/48 and in verotoxin 1 production in 91 verotoxin-producing Escherichia coli (VTEC) O103:H2 strains of bovine and human origins. None of the genes that were investigated appear to be virulence indicators for human O103:H2 VTEC.
