  • a There are a further 13 clonal groups with two STs per group, meaning that founders cannot be ascribed. Fifty-one singleton STs were also identified. Each ST was represented by one isolate.

  • b The predicted founder was ST162. The predicted founder of group 2 was ST433. Multiple candidates were predicted to be founders for groups 3 and 4. The predicted founders of groups 6 and 9 were ST66 and ST218, respectively. Multiple candidates were predicted to be founders of groups 5, 7, and 8.
