Malignant edema is a fatal infection of skeletal muscles and subcutaneous tissue of ruminants and other animal species, caused mainly by Clostridium septicum, but can occur in association with Clostridium chauvoei, Clostridium sordellii, Clostridium novyi type A and Clostridium perfringens tipo A. The definitive diagnosis of malignant edema must consider clinical data and necropsy lesions, microscopic features, isolation of the agent, direct immunofluorescence, immunohistochemistry and PCR. There are few reports in the literature concerning malignant edema in swine, and, the C. septicum, has been associated with most of the cases. This paper reports a case of myonecrosis and subcutaneous edema in a piglet caused by Clostridium septicum.
