Cladogram of S. equi ssp. equi seM sequences using a Neighbour joining method, with 1000 bootstraps. The diagram indicates the division of the strains into three major clades based on alignments of the sequence of seM amplicon. The names of the groups are the same as those given in Table 1. For multi-strain groups the number of strains present in each group is given in parenthesis (Irish strains, UK strains). Irish and UK strains that are not identical to any other isolate are indicated with EI and UK respectively followed by a strain number. The percentages given on the horizontal lines are the bootstrap values for the adjacent branch point on the right.
