Abstract

Multidrug resistance to streptomycin, sulfonamide, and tetracycline (AMR-SSuT) was identified in 156 of 171 isolates of Escherichia coli O157:H7 of phage types 23, 45, and 67. In 154 AMR-SSuT isolates, resistance was encoded by strA, strB, sul2, and tet(B), which in 59 of 63 tested isolates were found clustered together on the chromosome within the cdiA locus.
