Distribution of detected antimicrobial resistance and virulence genes. Isolate IDs consist of the horse ID, followed by “P” for pastern samples or “N” for nasal samples. Key for column ‘group’: “A” = horse affected by EPD, “C” = control horse. In the column ‘pretreatment’, the type of pretreatment of the affected pasterns is disclosed: “no” = no antibacterial pretreatment, “dis” = disinfectant, “ab” = antibiotic. Further details on the clinical data can be found in the supplementary material. For a detailed key of the depicted genes please refer to the caption of Fig. 6
