The histopathological changes in various organs of Cynoglossus semilaevis Günther infected with red abdominal shell disease were observed by dissection and HE staining. In the ill C. semilaevis, the body surface was congestive and bleeding;the skin in the blind side ulcerated with extravasated blood; the gill filaments ulcerated with a lot of mucus; the liver, pancreas and spleen were swelling and bleeding with extravasated blood; the small intestine was congestive and bleeding. Degeneration and necrosis, and submucosal bleeding occurred in the skin of C. semilaevis infected with red abdominal shell disease. There was red blood cell infiltration and deposition in the space among muscle fibers. Epithelial degeneration and necrosis occurred in the parotid gland. The efferent branchial artery was congestive. The myocardial fibers had a loose structure, and a large area of fracture appeared. The liver cells were swelling with degeneration and necrosis and concentrated nucleus. A large area of the renal interstitial was broken down and necrotic.
