  • a Data sets A and B included 18 supergroup A strains and 17 supergroup B strains, respectively (Table 2).

  • b The percentage of variable sites was estimated by considering indels in each data set variable sites.

  • c Recombination inferences for data set ABDF refer to events that occurred between supergroups.

  • d The organisms in parentheses are hosts of putative recombinant strains.
