FIG 2.

S. aureus isolates from a single rainbow trout purchased from a fish farm in London, England, fall within the diversity of CC45. Shown is a maximum likelihood phylogeny of 68 isolates of CC45 based on an LGA251 reference-mapped alignment with recombination removed and rooted using an outgroup from CC398 (with branches with a bootstrap support of <70 collapsed). Outer rings describe the host groups (a) and countries (b) from which isolates were sampled and the presence and absence of AMR genes (c), φSa3 prophage functional genes (d), and enterotoxin genes (e).
