Production of Verotoxin and Distribution of O Islands 122 and 43/48 among Verotoxin-Producing Escherichia coli O103:H2 Isolates from Cattle and Humans

摘要

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.
