Representation of shared spacer sequences within the CRISPR region of epidemic ST209 isolates relative to the 435 strain that was recovered from Sweden in 2008. (Left) The ML phylogeny of S. zooepidemicus. (Right) The presence of shared spacer sequences, from 1 to 44, is indicated by colored boxes, with the date of isolation, farm, and horse number shown in the columns on the right side of the chart. The location of isolates recovered from farm 5 is highlighted in the right panel. An isolate from farm 17 that contained an additional three spacers in its genome sequence is highlighted in green in the right panel.
