A five-month old female Great Dane with a history of depression and convulsion was submitted to the Pathology and Diagnosis Reference Division of National Veterinary Research and Quarantine service. The dog had ingested concentrated antifreeze and died 12 days after the sudden onset of clinical signs. Main gross lesion was limited to swollen kidneys with diffusely fine granularity on the cut surface. Principle microscopic lesions were focused on the kidneys including dilated Bowman's space, thickened glomerular basement membrane, many light yellowish crystals, and proteinaceous casts in some tubules. Some neutrophils and lymphocytes were focally infiltrated in interstitium of the cortex and medulla. Crystals were angular or quite irregular in shape and arranged in sheave or rosette form. Under polarized light, the crystals were birefringent, which is typical of calcium oxalate crystals. Crystals were more concentrated in the cortex than in the medulla. A few crystals were also observed in the small blood vessels of the brain. Based upon the history of ingestion of antifreeze and the identification of calcium oxalate crystals in the tissue sections of the kidney and brain, this case was diagnosed as ethylene glycol toxicosis in a dog.

Pseudomonas aerusinosa infection was diagnosed in broiler chicks, and was submitted to the National Veterinary Research and Quarantine Service in Korea. The total mortality rate was about 1,500 birds out of 22,000 broilers. Clinically, affected birds showed clinical signs including depression and anorexia with lameness and trembling of the leg. At necropsy, the dead broilers appeared to have omphalitis, yolk sac infection, fibrinous epicarditis, and fibrinous exudates in liver with swollen hock joint. Microscopically, there were multiple necrotic foci in the liver, fibrinous exudates in the heart, and infiltration of heterophils into the joint spaces of the hock joint. Pseudomonas aerusinosa was isolated from the heart, liver and hock joint, and the isolate was named P-200. In effort to estimate the virulence of P-200, 1-day-old chicks were challenged intramuscularly and intrayolksacally with the isolate. On the basis of mortality rate, the isolate P-200 was found to be highly virulent. This is the first report of an occurrence of Pseudomonas aerusinosa infection in broilers in Korea.

We report septicemic colibacillosis accompanied by white-spotted kidney in a 30-day old female Holstein-Friesian dairy calf. Grossly, there were numerous white spots sized average 0.5cm in diameter in both kidneys. When sectioned sagittally, there were radially oriented gray streaks extending outward and reaching the renal cortex. The renal papillae were ulcerated, white to gray in color and very friable. Histologically, there was extensive purulent inflammation characterized by severe neutrophilic cellular infiltrations in the tubular lumens and interstitia. In addition, massive coagulative necrosis were found in the apices of papillae. Numerous Gram-negative bacterial colonies were detected in both of the renal and lung tissues. Beta-hemolytic Escherichia coli (E. coli) was purely isolated from the renal parenchyma, peritoneal surface and pleural surface. Based on the above results, we suggest that the generalized septicemia with pyelonephritis may be oriented from the lower urinary tract infection with E. coli in this case.

Gloeocercospora sorghi caused the zonate leaf spot on sorghum (Sorghum bicolor Moench) in fields in Korea. The zonate spots were conspicuous on sorghum leaves as circular, reddish purple bands alternating with tan or straw-colored areas, which formed a coarsely zonate pattern. The lesions often occurred in semicircular patterns along the margin of leaves. The fungus produced sporodochia on the surface of infected leaves in a moist chamber. The conidia, born in a pinkish to salmon-colored slimy matrix, were hyaline, elongate to filiform, straight or slightly curved, 3- to 17-septate, and of variable lenght (28-197 x 1.6-$3.4\mu\textrm{m}$). G. sorghi isolated from diseased leaves of sorghum caused characteristic reddish-brown water-soaked leaf spots when inoculated to seedlings.

The present studies were conducted to monitor radioactive contamination in dairy products imported from 16 countries located in the East Europe which were affected by the Chernobyl nuclear accident. The 556 samples such as butter, cheese, ice cream, whey protein and hydrolysed milk protein products were collected randomly and determined from 1999 to 2002. All sample were below the Koeran and CODEX maximum tolerance level of radioactivity for $^{131}I$, $^{134}Cs$ and $^{137}Cs$.

Feline panleukopenia, also known as feline infectious enteritis or feline distemper, is a highly contagious generalized disease of cats caused by feline panleukopenia virus (FPLV) [2]. The disease is most severe in young, unvaccinated kittens between 6 and 24 weeks of age and is characterized by sudden onset of pronounced depression, anorexia and fever. The mortality rate ranges from 25 to 90％ in the acute form [1, 2]. This study was reports for the enteritis caused by the infection of FPLV in imported cats. (omitted)

We report the electrocution of Korean native cattle by a fallen electric wire, which caused the death of thirteen animals. The owner of the cattle felt an electric shock on touching the steel pen and found a fallen 220-V wire on the roof of the barn; additionally, the roof was singed. Clinically, the animals developed spasm, difficulty breathing, and excessive salivation. Histopathologically, many visceral organs revealed severe congestion or hemorrhage, which is consistent with previous reports. This study revealed that the proper installation of electric wires on farms is essential to prevent economic loss by electrocution.

To investigate the development of a subunit vaccine against theileriosis in cattle, the DNA fragments encoding piroplasm surface protein (p33) of Theileria sergenti of a Korean isolate were expressed in baculoviruses. The expressed p33 was characterized by indirect fluorescent antibody (IFA) and western blotting analysis. The expression of p33 was mainly detected on the surface of infected Sf21 cells by IFA. The immunoblotting analysis revealed the presence of a same molecular weight protein band of p33. The antigenicity of expressed polypeptide was further examined through the inoculation of a guinea pig. The sera of guinea pigs immunized with p33 expressed cell Iysate showed similar fluorescent antibody patterns and reacted with the same molecular weight protein of T. sergenti in immunoblotting analysis, thus indicating that this protein can be a promising candidate for a subunit vaccine in the future.
