PvuII ribotype patterns found within EcoRI ribogroups, which contain multiple serotypes. (a) PvuII ribogroups for DUP-1042 isolates. (b) PvuII ribogroups for DUP-1052 isolates. (c) PvuII ribogroups for DUP-1030 isolates. (d) PvuII ribogroups for DUP-1039 isolates. The ribotype patterns shown represent normalized data, and gels were run from left to right. Ribotype patterns within each letter grouping (A to I) are considered the same.
