Abstract

A 6-month-old female slaughter pig clinically showed pyrexia, polypnea and dysstasia with a deep stab wound in the muscles around the right scapula. Autopsy revealed that the affectedmuscles of the right shoulder to the back were dark reddish-brown in color, which were spongy with numerousgas bubbles and a rank odor. Histologically, coagulation necrosis was observed in the affected muscle fibers, and grampositive large bacilli were seen in the interstitium with edema and thrombophlebitis. An obligatory anaerobic rod was isolated from the affected muscles and lymph nodes, and the isolate was identified asClostridium novyitype A by physiological and biochemical characteristics.
