Purulent osteomyelitis caused by Arcanobacterium pyogenes was diagnosed in
three pig; aged between 3 and 4 months by radiological and pathological fin
dings. Osteomyelitis was localized in methaphysis and/or epiphysis of limb
bones. The prevalence of osteomyelits in swine seems to be underestimated b
ecause adspection of limb bones is not a routine procedure neither at slaug
hter nor at necropsy. Osteomyelitis may also have consequences for meat cut
ting. Osteomyelitis can be controlled by prophylactic procedures.
