5 isolates out of 66 were excluded
from this work because of their poor DNA preparation quality. The
isolates were grouped into three main clusters (A, B and C) at 70%
similarity cut-off. Cluster B included 17 homology groups consisting
of 44 isolates, while cluster A contained 5 homology groups
including 16 isolates. The isolate cTY53 formed a homology group
on its own (cluster C), and has the most distantly related profile.
