This is a case report that 24 heads of cattle suddenly died without clinical signs in a Hanwoo farm. The cause of death was Clostridium perfringens enterotoxemia resulted from them with feeding leftover food. The clinical signs were observed just before the death; increase of heart rate, shallow and rapid respiration, amyostasia, spasm and so forth. In autopsy, blood coagulation disorder, a little abdominal inflation, hepatomegaly and different size of red spots, congestion hemorrhage and undercurrent of bloody exudation were observed in the entire parts of small and large intestines. C. perfringens were isolated from the substantive organs, and a unique fragment of 405bp C. perfringens was amplified by PCR. Therefore, this case was diagnosed as enterotoxemia caused by -toxin of C. perfringens A type.
