  • An eight years old female barbary sheep (Ammotragus lervia), which bred at the Gwangju Uchi Park Zoo had shown anorexia, depression, respiratory problem for several weeks after parturition. In necropsy, extensive necrotizing pneumonia was found with severe immunocytes infiltration in the alveolar spaces and bronchioles. Pulmonary pleura were thickened with fibrin and inflammatory cells. Bacteria were isolated from lung and identified as Streptococcus equi subsp. zooepidemicus (SEZ) by biochemical tests and PCR on sodA and gusA genes, though seel gene was not detected. Isolation of zoonotic SEZ in public place such as a zoo should be emphasized for the public health mangagement.

  • A 3-year-old, intact female, Shih-tzu dog was presented with a 15-day history of vomiting,depression, and anorexia. On physical examination, systolic ejection murmurs with precordial thril atthe left heart base were detected. A diagnosis of congenital pulmonic stenosis (PS) was made mainlyfrom the thoracic radiography, electrocardiography, and echocardiography. On complete blood counts andconfirmed that main pulmonary artery was tremendously buldged and electrocardiography was suggestiveof severe right ventricular hypertrophy. Echocardiographic findings revealed the pulmonic valve stenosiscontaining valvular dysplasia and poststenotic dilation. On Doppler echocardiography, ejection velocityof the lesion accounted for 3.38 m/sec, meaning mild velocity through the stenotic area. The dog'sproblem and resulted in death. However, there has been no reliable relation between PS and CRF. Primarymalformation of pulmonic valve was confirmed at necropsy after death.

  • A 14-month-old, neutered female Miniature Pinscher was referred due to severe renal failure. The dog was treated with hysterotomy and followed by ovariohysterectomy (OHE) 6 days before the presentation. Excretory urographic and ultrasonographic studies revealed bilateral hydroureter and hydronephrosis. Postmortem necropsy revealed that ligatures were placed around the caudal portion of bilateral ureters in front of entrance into the bladder. This case shows that identifying and protecting the ureters are important during hysterotomy with OHE as well as OHE.

  • A one-year-old female sika deer died suddenly with no preliminary signs during exhibition at a zoo. At necropsy, the carcass was emaciated and had dried fur. Examination of the thoracic cavity revealed a diaphragmatic rupture measuring 2 cm in diameter and a fracture in the middle of the right eighth rib. The liver and lungs had irregular circular discolorations caused by diaphragmatic rupture and subsequent herniation. Dark-brown-colored ascitic fluid, hydrothorax, and yellowish hydropericardium were also observed. The cause of death was determined to be diaphragmatic rupture caused by a rib fracture, which led to respiratory imbalance and circulatory disorders.

  • The intestines and hearts of dogs were examined for Toxocara canis, Toxascaris leonina, and Dirofilaria immitis, after necropsy between June 26 and September 29, 2004 in Chuncheon, Korea. Of the 662 dogs examined, 6 were infected with T. canis $(0.9\%),\;86\;with\;T.\;leonina\;(13.0\%)$. Fifty dogs were infected with D. immitis among 500 dogs examined $(10.0\%)$. Five were co-infected with T. canis and T. leonina, and three were co-infected with T. leonina and D. immitis. The cumulative positive infection rate for three species was $134/662(20.2\%)$. Considering previously reported seropositive rates of T. canis excretory-secretory antigen, i.e., $5\%$ in the adult population in Korea, the possibility of toxocariasis caused by T. leonina should be reevaluated.

  • A case of chronic cholangiohepatitis associated with Eimeria spp. is reported in a 6-month-old, male, native Korean goat. The goat died after having a 1-week history of diarrhea, anorexia and weight loss. At necropsy, numerous multifocal to coalescing, pale and mottled red foci were present throughout the liver. Histologically, numerous coccidian parasites in both sexual and asexual stages were found in the intrahepatic biliary epithelia and bile duct lumens. Based on the light microscopic and ultrastrastructural features, the parasites present in the liver were compatible with the genus Eimeria ; however, the species was not speciated.

  • Twelve colostrum-deprived piglets were inoculated oral1y with porcine epidemic diarrhea virus isolated from Korea. The piglets were euthanatized from at 12 hour postinoculation(PI) at 6-hour intervals. At 24 to 36 hours PI, all infected piglets showed severe yellowish to watery diarrhea, dehydration, depression, and anorexia. At necropsy, the intestinal wall looked thin, mesenteric vessels congested, and mesenteric lymph nodes edematous. The histological findings showed marked villous atrophy and fusion, severe degeneration of enterocytes and monomuclear cell infiltration in the lamina propria. On electron microscopy, villous epithelial cells of infected jejunum contained viral particles at 18 hour PI. The viral particles were pleomorphic spheres with a mean diameter of 95∼180nm including 18nm projections.

  • Aspergillosis, caused by infection with Aspergillus fumigatus and less commonly by other Aspergillus species, is a prevalent and costly respiratory disease of poultry, In a flock of chicks, the number of birds, 4∼5 months old, had become gradually emaciated and subsequently died. Gross necropsy revealed multiple granulomatous masses on the abdominal serosa. The masses, 4∼15 mm in size, were attached on mainly intestinal wall. Also, the smaller masses in size were on mesentery and pancreas. However, only a few small white nodules were scattered throughout liver and lung in few samples. Microscopically, the mass were granulomatous with a central area of necrosis containing numerous septate, branched fungal hypae consistent with Aspergillus sp. These were surrounded by macrophages, giant cells, lymphocytes and fibrous tissues. Nodular lesions of liver and lung were seemed to spread hemotogenously from intestine and the possible route of infection was speculated by oral. This report is a Aspergillus-induced granuloma limited to the serosa of abdominal cavity, especially of intestinal wall.

  • A male badger which showed depression and bloody diarrhea was submitted to Iksan Branch of Chonbuk Veterinary Service Laboratory for necropsy on May 1998. Grossly, paleness of the mucous membranes was observed and the small intestinal contents were hamorrhagic. The numerous tiny hookworms, sized in 5-10 mm and greyish-white in color, attached to the intestinal mucosa. Male bursa was well developed. Histologically, intestinal lumen was filled with hemorrhagic contents, which contained worms. The epithelial cells of the villi were underwent degeneration and lamina propria was infiltrated by lymphocytes and plasma cells, and goblet cells were hyperplastic. There were rounded cutting plates in the funnel-shaped buccal capsule and transverse striation on sheath in hookworm, ultrastructurally, which were consistent with Uncinaria sp. The shape of eggs were ellipsoidal and morula, and some eggs contained a mobile larva. It was concluded that this badger was infected with Uncinaria.

  • A female slaty-backed gull (Larus schistisagus) died suddenly without apparent clinical signs. At necropsy, well demarcated 7 to 10 mm yellow to white nodules were presented at the lungs and thoracic cavity. Microscopically, multifocal necrotic granulomas were observed in the lung tissue and amorphous acidophilic fibrin were accumulated in the granuloma and normal alveolar space. Periodic acid-Schiff (PAS) staining demonstrated numerous pinkish red branched hyphae embedded in the center of these granulomas. According to fungal culture using Sabouraud's dextrose agar plate, Aspergillus fumigatus was isolated from lung lesions. This is the first report for pulmonary aspergillosis of wild slaty-backed gull in Korea.
