Abstract
Necrotizing infectious enteritis provoked by CI. perfringens type C has been diagnosed with increasing frequency among piglets in Danish herds since 1963. On a clinical basis the disease is difficult to differentiate from other enteric diseases (Høgh 1967). In the small intestine, the infection gives rise to postmortem findings which, under Danish conditions, have not been observed in any other disease affecting baby pigs. The aim of the present study is to describe the patho-anatomical and histo-pathological changes which occur in spontaneously infected pigs.
