  1. aSome data from these pigs have been published previously: pigs 1–3 [14, 15], pigs 5–8 [16], and pigs 1–9 [40, 41]
  2. bPigs 8 and 20 were diagnosed with osteomyelitis by necropsy and/or histology disclosing affection of the proximal and intermediary phalanges of toe no. IV in pig 8 and the intermediary and distal phalanges of toe no. V in pig 20; by scanning, only one of the lesions in each of the pigs was identified
  3. cS. aureus identified by cultivation from a periosseous abscess (pigs 2, 3, 9–12, 14, 17–18), from an arthritic lesion (pig 8), from an inoculation site abscess (pig 19), and by immunohistochemistry (pigs 5 and 20)
