A case of iatrogenic myositis in piglest

Abstract

A case of infectious myositis due to yatrogenia was observed in weaning piglets. Six piglets from four litters were affected showing unilateral and bilateral hind limb, knuckling of the metatarsalphalangeal joint, inability to move, dog sitting position, and hyperflexion of the posterior digits.Necropsy findings showed: osteochondrosis, osteomyelitis, bubos increased more than 30 times the normal size and, abscesses between phalanges. Other conditions seen were: iron spots in semitendinous and semimembranous muscles, aqueous blood, paleness and splenomegaly. It was concluded that the skeletal disorders and the lameness with buboalgia seen in these pigs were caused by inadequate iron injections performed by unskilled workers at the farm.
